    1.0 INTRODUCTION TO OPUS

    Gidday!

    Welcome to Opus, the Computer-Based Conversation System.

    You are given a limited licence to use the Opus-CBCS program as long
    as you use it in a LAWFUL and FRIENDLY manner. This is NOT public
    domain software and you are required to to follow the two licence
    requirements. There is no monetary fee.

    You may freely distribute the Opus-CBCS program, but it is not to be
    sold. If your system has a user fee, for example, you may not have
    Opus-CBCS online for download unless anyone who has not paid the fee
    can also download Opus-CBCS. Nobody is ever to make money from the
    distribution of the Opus-CBCS software.

    If you bought Opus-CBCS on diskette or by download, demand your money
    back in some lawful but unfriendly manner and report the vendor to
    your nearest Opus-Info system.

    If you need, or want, to say thanks for this system in some monetary
    way, you can send $50 to AmFAR/5900 Wilshire Boulevarde/Second Floor,
    East Satellite/Los Angeles, California 90036-5032/USA. AmFAR is the
    Americcan Foundation for AIDS Research, a non-profit, non-political,
    and non-affectational organisation that funds hundreds of AIDS
    research projects throughout the world.

    The Opus-CBCS program is copyright software. The copyright is held by
    Wynn Wagner III. The sole purpose of the copyright is to ensure that
    the Opus-CBCS program remains available for no money. The copyright is
    enforced.

                         +----------------------------------------+
                         | Free?  Does this mean I can't          |
                         | get a discount?                        |
                         |                                        |

                         +----------------------------------------+

    Because no money is charged, Opus sysops are not consumers.  Opus is a
    community effort.

    1.1 GUARANTEE

    You have to be kidding!

    Opus-CBCS carries only one guarantee: if you break it, you own all the
    parts. To put it another way, if you run Opus, you do so entirely at
    your own risk.

    The Opus-CBCS program may or may not work under your particular
    circumstances. If it does work, it is possible somebody will invent a
    way to destroy everything on your system. Opus contains lots of
    security features, but those features don not come with any sort of
    guarantee.

    However, you are most definitely not on your own. The Opus Community
    throughout the world are always willing to help, provided you observe
    the lawful and friendly Opus-CBCS licence requirements. Your best
    source of information and help is the FidoNet MEADOW echomail
    conference. There are also Opus-Info help systems in the USA, Europe,
    Taiwan and Australia.



    1.2 USING OPUS

    Lawful and Friendly are the important words.  The original author, and
    copyright holder, of this software takes the license quite seriously,
    and if you use Opus you have to do so in a lawful and friendly manner.



    1.3 CREDIT AND GRATITUDE

    The following folks have gone out of their way to help the Opus
    project. This is the "Opus: Sine Qua Non" (the list of folks, without
    whom there would be no Opus):

    WYNN WAGNER III     First Opus-CBCS author. Opus-CBCS copyright
                        holder. He came, he coded, he produced Opus-CBCS.

                        standard.

    GEORGE STANISLAV    The first Opus V1.03 to V1.10 author or "LCD"

    DOUG BOONE          The second Opus V1.10 author; he pushed, coded,
                        and kicked the Opus V1.10 release out the door
                        when the world was wondering  "Will Opus V1.10
                        ever be ready?". Also responsible for Opus V1.11
                        through V1.14.

                        Not knowing the meaning of the word "quit", and
                        ever a glutton for punishment, Doug also coded

    JOHN VALENTYN       The Opus V1.70 files database coder, and adoptive
                        parent of Doug's Opus File Area Manager (OPUS-FAM)

    ULF NILSSON         Opus V1.70 Language Coordinator, managed to find a
      and               group of people to keep their translations current
    TRANSLATORS         while Opus V1.70 was in development AND put up
                        with the "normal" American Anglocentric attitudes
                        and misconceptions. Providing full language
                        support would have been impossible without all
                        your help.

    THOMAS SUNDBLOM     Who provided the idea for the automatic character
                        set translation and gave us permission to use his
                        table of character sets.

    TREVOR ROYDHOUSE    Opus V1.70 Document editor and author. Who did
                        more typing?

    PAUL KELLY          Three Opus V1.70 beta testers who seemed to find
    MICHAEL MASTERSON   an unlimited number of bugs, quirks and oddities.
    BEV FREED           And provided an unlimited supply of suggestions.


    In addition to the active participants, the following should be
    mentioned for doing things without which we would have no Opus:

         Ward Christensen    He thought up both XModem and bulletin
                             board systems.

         Tom Jennings        He originated the worldwide amateur
                             electronic mail network now known as
                             FidoNet <tm>.

         Chuck Forsberg      He designed ZModem, the fastest and most
                             reliable streaming file transfer protocol
                             available.



    1.4 DOCUMENTATION, CREDITS

    The Opus CBCS Sysop Operations Manual is intended to be a practical
    "how to" guide to setting up, customising and operating Opus V1.70.

    This manual is not the place to look for highly technical information
    on Opus V1.70; for that you should refer to the Opus Technical
    Reference Manual. Nor was it written as an installation or conversion
    manual for Opus V1.70 (although it may help); for those you should
    refer to the Doug Boone's STARTUP.DOC and CONVERT.DOC files.

    No document would be complete without giving credit to those who
    contributed to the effort. First and foremost, I want to thank DOUG
    BOONE. Again. Heaven only knows how he found the time, but he was
    always there to answer my questions and look over the documentation,
    even at the eleventh hour. I also have to thank my wife, Adrienne, who
    has put up with my living in front of this screen and keyboard for
    the last couple of weeks and more than usual anti-social behaviour.

    Others who contributed to this documentation included (in
    alphabetical order): Bob Davis, Beverley Freed, Dave Hatch, Tom
    Kashuba, Paul Kelly, Robert Lilly, Robert Michal, Graham Stair, George
    Stanislav, John Valentyn, and Wynn Wagner III.

    Who were the rest?  Maybe you?  How?  I cannot stress enough how
    valuable a resource the MEADOW echomail conference is when it comes to
    information about Opus. I have been an avid reader of the conference
    since it first became available in Australia in 1987. If you do not
    regularly read the MEADOW, you are most definitely missing out on part
    of Opus and the sense of Opus community.

    2.0 OPUS V1.70 OVERVIEW

    Opus is an evolving computer-based conversation system that combines
    simplicity with configurability.  Simplicity, in that a novice can
    have a rather nice bulletin board up and running very quickly.
    Configurability, in that an advanced sysop can turn the customization
    of the board into an art form.  It is entirely up to you!

    Therein lies Opus's charm: it has all the power an advanced sysop
    demands, while still being easy for both the user and the system
    operator.

    Opus provides a feature-rich electronic messaging system, wide choice
    of file upload and download protocols, plus access to the world's
    premier amateur electronic mail network.  Clearly, it would be a
    bargain at twice the price!



    2.1 WHAT IS NEW IN OPUS V1.70

    Opus 1.70 is a major internal structural change that is moving towards
    more of a database design instead of having tons of little files out
    there with which to deal. And yes Virginia, we are still in the small
    memory model.

    One important point to realize is that you can throw out nearly all the
    limitations that were in Opus 1.14.

    2.1.1 SYSTEM FILES

          The SYSTEM*.DAT files are gone, replaced by a mini-file area
          database and mini-message area database and five index files.
          These index files are true buffered Bplus trees which will give
          you very fast lookups.



    2.1.2 USER AND EVENT FILES

          * The event file is largely the same as Opus V1.14. There is
          some new information in the header of the schedule file to track
          the ID's of new users;

          * In the user file there is some new information added (see
          configuration & history menu details below);

          * the lastread pointers stored in the user file are superseded
          by individual last read pointer files in each message area. Opus
          now keeps track of the highest message read and the last message
          read separately;

          * The user file is indexed using a buffered Bplus tree to give
          fast lookups;

          * Opus is also tracking the total number of messages that a user
          has read and the total number of messages that they have
          entered.



    2.1.3 USER KEYBOARD MACROS

          * Opus will store 3 user keyboard macros (message, file macro
          and default) of up to 15 characters in the user record.

          * Opus will choose the macro that matches where the user is in
          the menu structure. If the user presses the macro key in the
          message menu, Opus will execute the message macro. Opus will
          execute the default macro at any menu except the message and
          file menus.



    2.1.4 MENUS

          * In HiTech the '>' after MORE in HiTech is blue and will
          flash, which hopefully will draw people's attention to it;

          * You can substitute your own menu prompts;

          * Users can choose to have the number of minutes remaining
          displayed as part of the menu prompts;

          * NACL will allow '*', '@' and '&' for menu options;

          * You can define a file to be displayed to users as fancy, slow
          ASCII graphics menu at the MAIN / CONFIG / SYSOP / SECTION /
          CUSTOM menus if the user has graphic (ASCII) menus turned on.
          The Opus menu will follow unless the user's help level is
          "expert".

          * The echomail and matrix menus have been eliminated. Instead
          there is one, single message menu for all areas.

          SECTION MENU

          * Sections are used to break an Opus into "sub-boards" or
          "sigs". You might have a "Programming Section". File and message
          areas that relate to programming would all list that as their
          section, and underneath that you might have a "C Section" and a
          "Modula 2 Section" and so on. When a user goes into a section
          they only have access to other areas that match that section.
          Message Scan and file Locate for example would be narrowed down
          by going into a section.

          * Sections are selected/used like locks and keys, except that
          users can directly change their sections.

          * Users can make their own selection of message and file areas
          to be included in user defined sections. Opus remembers users'
          sections next time they logon. Users can choose to unselect
          their user defined, or sysop defined, section and revert to
          none.

          CONFIG MENU

          New configuration options allow users to:

          * always return to their last menu after logging on, AFTER going
          through the usual logon procedure. The only difference is that
          instead of the MAIN menu being the menu where users are dumped,
          it will be the last menu they used on their last call;

          * select what type of graphics to use every logon, right after
          giving their password;

          * have hotkeys at all help levels;

          * get long, tedious graphic (ASCII) menus in addition to the
          Opus menus;

          * display the number of minutes left online for this session as
          part of the menu prompt;

          * turn on/off being interrupted by other users on a multiline
          system with multiline chat available;

          * set a default file transfer protocol. ***WARNING*** This may

          mess up the Zmodem "R)Zupload" that a lot of us use.

          HISTORY MENU

          * The configuration menu has been split into a "history menu",
          which is information about the user (eg password, city,
          language, telephone, alias, street address, birthday, and how
          listed in the user list) and a configuration menu which is how
          the user sees Opus.

          * Users can now change their logon name.

          * Users can now change their alias.

          * The history menu can be added to any menu, eg the main menu or
          the configuration menu, or both.

          MESSAGE MENU

          New options allow users to:

          * search forward from the next message to the last message
          looking for messages that are To: the current user. When it
          finds one, Opus stops and displays the message;

          * search forward from the current message looking for a match to
          a string that the user provides, then displays the messages it
          finds. This command remembers the last search string that a user
          asked for, so hitting a return will allow a user to continue a
          search without having to type in the string for each match;

          * review the rules at any time, even after reading messages. It
          is a "smart" menu item which only appears on the menu if
          RULES.BBS or RULES~.BBS exist in the message path;

          * allow users to enter a message to Sysop from wherever the
          option is available. It is a variant of the logoff message in
          that users are not asked for names or subject or anything.

          FILE MENU

          New menu options added to allow for:

          * searching the entire files database for files added since the
          user's last call, or the user can override it and specify a
          number of days;

          * downloading and automatically disconnecting if Opus thinks the
          download went successfully;

          * H)urling files across drives if there is enough room on the
          target drive;

          * setting a temporary upload/download path. Opus will not ask
          for descriptions for files uploaded in the temporary directory
     
     
    OPUS V1.70 OVERVIEW                                          Page 17 
     
     
          and they will not be included in files database.

          * adding files to the files database from the keyboard.

          CUSTOM MENUS

          * Opus V1.70 allows the sysop to create up to 6 different custom
          menus. These menus may be attached anywhere. There is a
          limitation: only "global" menu commands can be attached to
          custom menus (refer to section 3 of the Opus V1.70 Technical
          Reference Manual).

          LORE/OPED MENU

          * New editor command to have Opus ask for a filename. If you
          have started editing a message, it is lost, only the file is
          saved;

          * The LORE help file will be shown the first 2 times the user
          enters a message via LORE, instead of during the first 5 calls.



    2.1.5 VERSION 7 NODELIST SUPPORT

          * Uses less than 70% of the disk space needed for the Version 6
          nodelist, includes Sysop names, will insert Sysop name in net
          mail. Use of the Version 7 nodelist is optional, Opus still
          supports the outdated Version 6 nodelist.

          * If you do use the Version 7 nodelist then Opus will list the
          Sysops when listing boards.

          * When Polling between callers, Opus will accept either an
          address or a Sysop name.

          * You can set the privilege needed to see who the Sysops are for
          the boards when listing boards in netmail or from the Matrix
          Menu.



    2.1.6 SYSTEM SECTION

          * Opus will optionally answer the phone itself instead of
          relying S0=1 in the modem initialization string.

          * Opus will support the new HST/DS HST modem CONNECT 14400
          connect message.

          * You may specify the path to find/put echotoss.log and also
          the name of your echotoss.log. Opus now uses echotoss.Log for
          its internal echomail scanner, so external programs that use the
          echotoss.log will be picked up by Opus.



    Page 18                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


          * Enable multiline chat ... this is not a real multiline chat,
          but at least messages can be sent between tasks.

          * Tell Opus that its being run on a LAN and it should behave
          like a multitasker was being run (ie create INMAIL##.$$$ files).



    2.1.7 LANGUAGE SECTION

          * Opus supports the multiple character sets as set out in the
          file FSC-0050 and as implemented in the program OPMED 3.0;

          * The number of user-defined languages has been expanded from 6
          to 12;

          * Option to change the IBM line-drawing characters in Opus to
          lotek ASCII characters instead of the high-bit characters.



    2.1.8 EQUIPMENT SECTION

          * Rudimentary MOUSE support (sysop configurable on/off)

          * Four configurable predial strings for dialling outbound calls.
          Opus will check the Modem byte in the nodelist, and if it is set
          to one of these values Opus will use the predial string that
          corresponds to the first match. If no modem flag has been set
          for a node, Opus will use its default dial prefix string.



    2.1.9 MATRIX AND ECHOMAIL SECTION

          * You can increase a user's Matrix Credit while a user is
          online;

          * A new option to tell Opus that if it cannot find an address in
          the nodelist to send the mail to the Net Host instead of marking
          it as "undialable". (This only works with the Version 7
          nodelist);

          * New options to ask users of the specified privilege and above
          whether the message is a file request or an update file request.

          MULTI-ZONE SUPPORT

          * Opus will handle multi-zone holding areas (ie zoned outbound
          directories: outbound.###).  You can still put everything in a
          single outbound directory, but if they exist Opus will use the
          outbound.### directories;

          * If you give an address in the definition of an echomail area,
          Opus will use that address in your messages from that area;
     
     
    OPUS V1.70 OVERVIEW                                          Page 19 
     
     
          * If you have multiple zone / net /node addresses, Opus will
          use its "best fit" address for the calling/called node in the
          YooHoo packet instead of the first (primary) address.

          POINTNET SUPPORT

          * Opus will run as a BOSS node and strip off a point's SEEN-BY
          and Origin lines and put on yours;

          * Opus will also run as a point;

          * You can either be a BOSS or a POINT, but not both.

          EXTERNAL MAILER HOOKS

          If you give the CTL file an External Mailer string to look for,
          if Opus sees that string at the name prompt it will create a
          "MAILER.BAT" file and exit with the specified DOS errorlevel.

          UUCP SUPPORT

          * When forwarding messages to the netmail area, if the message
          is "To: uucp", Opus will not insert the From/To/Date stuff at
          the head of the text of the message so the UUCP address will be
          preserved as the first line in the message;

          * UUCPlist is like FidoUser.Lst, except it is a list of UUCP
          addresses, not FidoNet addresses. If this option is on, you
          simply enter Netmail messages with the person's name on the
          address line;

          * If a message has a UUCP address on it, you can set a privilege
          level for a new command that will allow some people to delete
          the UUCP address that has been read out of the original message;

          * When entering a message to "UUCP", Opus will put in the
          address of your UUCP gateway automatically;

          * In the MATRIX section of the CTL file you can specify an
          address so that if Opus is sending a reply back to a UUCP
          address, the message will be routed to this address
          automatically instead of wherever it entered FidoNet.



    2.1.10 SESSION SECTION

          New options added to:

          * use/update LASTREAD for the Sysop who uses an external message
          editor;

          * define the file to be displayed if user does not get the
          password right;



    Page 20                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


          * define a file where all downloads will be logged;

          * define a file where all uploads will be logged;

          * encrypt the users' passwords in the user file (they cannot
          then be unencrypted);

          * control the privilege needed to download or check the contents
          of files that are not listed in the files database.

          USER LOGON

          New options added to:

          * prompt new users for either their ALIAS or REAL name at first
          logon after they have entered their name the first time;

          * allow new users to choose from the languages the sysop has
          made available;

          * toggle on/off whether or not to ask new users for their
          city/state;

          * specify a default number of days until new users' access
          expires;

          * specify a default number of minutes until new users' access
          expires;

          * specify default keys for new users;

          * specify a default section for new users;

          * define a file to help the user with new user logon
          configuration;

          * allow users / new users who have a specified privilege to
          logon without giving any password.

          SPECIAL CONFIGURATION LOGONS

          * A user, even a new user, can enter their name plus a string of
          configuration commands at logon. These commands will override
          whatever has been stored in the user record or, if it is a new
          user, bypass the "Mirror shades" questions entirely;

          * Opus will accept name1 name2 /pmypwd for quick logons.

    2.1.11 FILES DATABASE

          This is actually a system of three files. One file contains all
          the information about what files you have on your board, one is
          the index to all the filenames on your board, and one is an
          index into the first file in each file area.

          * You can specify where in each file area listing new files will
          be added either when uploaded or hurled. Normally new files are
          appended to the end of the listing.

          * You can specify full paths to files if they are not in the
          default directory for that area.

          * Who uploaded the file, and when, is stored with each file.

          * The file date and time is preserved when files are received
          via Zmodem transfers. The search for new files will look at the
          upload date/time, but the users will see the actual file
          creation time when they do a F)iles listing.

          * When a user does a L)ocate, or searches for a string with the
          F)iles command, they will also optionally get an additional line
          of information including who uploaded the file, when, and how
          many times it has been downloaded.

          * The F)iles display has been modified so it does a word-wrap
          for users who have screens wider than 60 characters.
          Descriptions can be up to 256 characters each.

          * Each individual file can have its own download privilege and
          locks.

          * When attempting to do a download, if the file is NOT in the
          current area, Opus will try to jump to the area where the file
          is located. Privileges and locks are honoured.

          * Opus will not allow users who have privilege below ASSTSYSOP
          to upload duplicate file names anywhere unless you specifically
          allow duplicate files.

          * If a user has never been in a file area, Opus will show them
          a RULES file if one exists.

          * You can specify file areas from which files may be downloaded
          without being counted as part of the ratio or daily download
          limit.

          FILE AREAS

          * File and Message areas are now completely separate. There is
          no place where they interact with each other. Even the barricade
          paths can be completely separate;

          * In both the file and message areas you can embed an


    Page 22                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


          "applications" string in the area definition in the database for
          use by, eg, an intelligent message renumberer;

          * The number of external protocols Opus will accept has been
          increased from 8 to 16.

          * During a file L)OCATE, Opus will list the areas as they are
          checked.

          New options added to:

          * define what section(s) an area should be considered to be part
          of;

          * define a file in each file area to be shown before the file
          listing;

          * specify a private upload path;

          * specify a private upload path user privilege. Uploads from
          users with the specified privilege or greater will go to the
          private path;

          * specify a private upload key;

          * specify a private upload key path where uploads from a user
          with the private upload key will go;

          * define a file to be displayed to a user before the Opus menu
          for this file area if they have graphics (ASCII) menus turned
          on;

          * define ratio privileges in file areas. Ratios only come into
          effect if the user's privilege is equal to or below what you set
          for that area;

          * specify the privilege necessary to display the information
          stored in the files database on who uploaded new files;

          * allow duplicate files to be uploaded in a specified file area.
          Opus will then not check for duplicate files when uploads start
          in this area;

          * specify that files uploaded in a particular area will be
          assigned a specified privilege for downloading;

          * show the two-line listing instead of the single line listing;

          * specify a privilege level for displaying who uploaded files
          (the date of upload and how many times downloaded info will
          still display in two line listings).

    2.1.12 MESSAGE AREAS

          * File and Message areas are now completely separate. There is
          no place where they interact with each other. Even the barricade
          paths can be completely separate;

          * In both the file and message areas you can embed an
          "applications" string in the area definition in the database for
          use by, eg, an intelligent message renumberer;

          * Opus will check to see if private messages are to either the
          user's name or current alias.

          * The 10k limit on echomail messages has been lifted, instead
          you can specify a limit in the CTL file from 3k up to 60k;

          * The 60 line limit on messages has also been lifted. Instead in
          each area you can specify a maximum number of lines, the default
          is 60, and Opus will give users that many lines or as many as it
          can in the amount of free memory it has available. The range of
          lengths that NACL will allow is from 10 to 250 lines.

          New options added to:

          * specify the keys needed to access the message upload command;

          * specify the privilege required to use the message upload
          option for this area;

          * specify the keys needed for users to read PRIVATE messages
          that are not to / from them;

          * specify the privilege needed for users to read PRIVATE
          messages that are not to / from them;

          * define a file that will be shown to users who have graphics
          menus on before the Opus menu;

          * define an ORIGIN line for use in each echomail message area;

          * specify a DOMAIN for use with MSGID in a message area;

          * specify the ADDRESS for use in an area for the Origin line,
          MSGID, and SEEN-BYs.

          * specify the addresses to scan mail to. Opus V1.70 will scan to
          255 addresses per area;

          * changes to the next area that has new messages in it up to the
          high message area set in the CTL file.

    2.1.13 OPUS EMBEDDED COMMANDS

          * Skip the rest of the line if user section is equal to
          specified section;

          * Skip the rest of the line if user section is not equal to
          specified section;

          * Show the last date/time the user accessed a particular file
          area;

          * Show a specified file and return to the current location in
          the original file;

          * Show the rest of a line only if the user's baud is greater
          than or equal to a specified baud;

          * Record the current position in the current file, jump to
          specified position in the current file and return to original
          position when specified;

          * Stuff commands available from the current menu into the
          command buffer and quit the OEC file;

          * If the user's help level is not equal to the help level on the
          line, the rest of the line is skipped.

          * Add specified keys for the user. This in addition to the
          default logon keys which may be specified in the control file;

          * Clear specified keys for the user;

          * Display the total number of messages a user has read;

          * Display the total number of messages entered by user;

          * Get and save a string up to 58 characters long from the user.
          When Opus hits a ^OC or ^OH or ^OG, whatever the user has
          entered will be appended to the command you gave.

          * Log special debugging info;

          * ^OC rereads LASTUS##.DAT, now there is an OEC that is
          identical in function, except that LASTUS##.DAT is not reread;

          * Send a message to the user on the current task. Sounds useless
          right? Well, suppose you added it to the end of BYEBYE.BBS ...

          * The ability to stack OEC files, where one file calls another
          and then returns to the original point;

          * Send a message to a specified task (like the inter-line chat
          menu item);

          * See who else is online on multi-line systems;

          * Look for the interline CHAT## file and display it if it
          exists;

          * An OEC like ^OC which does not fill the command buffer with an
          ENTER when it returns;

          * An OEC like ^OC which does a system() call, does not re-read
          LASTUS##.DAT, and does not fill the command buffer with an
          ENTER when it returns;

          * Check for the existence of a specified filename. If the file
          does not exist, the rest of the line is skipped;

          * Run a program and return the DOS errorlevel of the program
          that was called;

          * Run a program (as above), but do not re-read LASTUS##.DAT;

          * Compare the DOS errorlevel returned from the program run
          (operates just like "if errorlevel" does in DOS batch files).



    2.1.14 COMMAND LINE OPTIONS

          * Force Opus to do an EchoScan right away.



    2.1.15 NIEL KEYS EXTENSION

          Opus will execute a batch file in the miscellaneous directory
          that corresponds to the function key pressed when it is waiting
          for a call.



    2.1.16 EXTERNAL PROGRAMS

          Programs that are called from the menus as _OUTSIDE items, Opus
          will pass everything else that the user has typed as arguments
          after filtering it.  Opus will filter  out <>/\-":' characters.



    2.1.17 ERRORLEVEL EXITS

          * Exit after upload;

          * Exit after local messages entered.





    Page 26                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    2.1.18 TRULY MISCELLANEOUS

          * More [Y,n,=]? When users are listing areas, they quite often
          just type in a number and Opus says something about, "I do not
          understand 27, Use 'Y' for Yes and 'N' for No.". 1.70 will just
          accept the number as an area selection and go on;

          * Opus will log the size of the file in file transfers,
          including mail transfers;

          * The low-level disk routines have been stripped down, the rust
          scraped off and they were all chromed and converted to _fastcall
          calls;

          * If the Sysop puts a jump to another menu but never defines
          that menu, users were cut adrift in limbo. Now Opus will check
          to make sure that there really is a menu to go to, and if not,
          will log the error, tell the user to tell the Sysop about it,
          and send them to the MAIN menu;

          * "Press ENTER to continue" will pass along any commands that
          have been typed in;

          * Fixed the timer so that if Opus is re-started with fewer than
          3 minutes before a "hard" event, Opus will know that it should
          go into its "pending event" mode and drop DTR so no incoming
          calls will be accepted.



    2.2 REQUIRED HARDWARE

    In general, you have a reasonable chance of getting Opus 1.70 to work
    on any MS-DOS computer. Opus V1.70 uses a little more memory than
    V1.14 to do some tricks. In Opus V1.14 the "minimum" was 128k plus the
    size of the nodelist index file. For Opus V1.70 the minimum is 128k
    plus the size of nodelist index file plus the size of the largest
    *.USL file in your language directory; and if you are using the
    internal echomail scanner in Opus V1.70, add the size of the maximum
    echomail message you want to be able to handle. In most cases, you
    will want to be able to run external programs (eg file compressors and
    uncompressors) from Opus, and that requires anywhere from 256k to 400k
    depending on the file compressor you choose.

    Hardware incompatibilities are resolved through a special program
    called a FOSSIL. It contains modem, keyboard and video methods for
    specific hardware configurations. It means the same version of Opus
    can run on an IBM PC, an IBM PS/2, a DEC Rainbow or a Tandy 2K. The
    only difference is the FOSSIL program.

    Theoretically, Opus will use any modem that uses the Hayes command set
    and supports DTR. It has been successfully tested with the USR DS/HST,
    Telebit, Netcomm, Dataplex, MultiTech and the Hayes families. If you
    use another modem brand, Opus should work but there are no guarantees.
    If you get other brands of modems to work with Opus, please contact
     
     
    OPUS V1.70 OVERVIEW                                          Page 27 
     
     
    one of the Opus-Info nodes and let them know the brand name, the
    initialization string and what you did to get it to work.

    Also, Opus REQUIRES a storage device larger than a floppy drive.
    Generally, this will be a hard drive, but could just as easily be
    cartridge media such as a Bernoulli Box. There are absolutely no plans
    to release a version that will run on floppies; the support files
    simply take too much room.



    2.3 REQUIRED SOFTWARE

    Several pieces of software are required to make Opus work. A couple
    are worth singling out. First, DOS 2.1 or higher ... 2.0 and below are
    NOT supported. In fact, not all the Opus features will work under DOS
    2.1. DOS 3.1 or higher is recommended for a fully-featured Opus
    system. There are no guarantees that DOS 2.1 will be supported in
    future releases of Opus.

    Next, the FOSSIL. This is where Opus's low-level communications
    routines live. The FOSSIL is a memory-resident assembly language
    program or device driver designed especially for Opus. It supplies the
    routines Opus needs to communicate with the modem. If you are running
    other memory-resident programs, you may experience difficulty with the
    FOSSIL. Installing the FOSSIL last may solve the problem, but it is
    NOT guaranteed. Switching to another FOSSIL may also solve your
    problems.



    2.4 MESSAGES

    Messages can be of three basic types, or scopes: local, Matrix and
    echomail.  A message's scope determines its behavior on an Opus-based
    system.



    2.4.1 LOCAL MESSAGES

    Local messages are the simplest form available, common to almost all
    BBS systems.  Local messages are available to a predefined group of
    users on a single BBS -- the one where they were entered.



    2.4.2 MATRIX/NETWORK MESSAGES

    Matrix is the Opus word for network. This was chosen because of the
    ambiguity associated with the word "network". The Matrix is defined as
    a group of bulletin boards which can exchange information via the
    public switched telephone network (PSTN).



    Page 28                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    Opus V1.70 can place outgoing Matrix calls, and receive incoming mail
    from other Opera, or other systems running either the FidoNet<tm> or
    WaZOO matrix protocols.



    2.4.3 ECHOMAIL MESSAGES

    EchoMail provides a means of maintaining the same message base on
    multiple bulletin boards. This allows conferencing -- even
    internationally -- if you choose to do so. Remember, phone calls
    placed for mail transfers cost the same as regular calls. Be aware
    that anything involving Matrix transactions can involve long distance
    phone charges.



    2.5 EXTENDED MESSAGE AREA ATTRIBUTES

    A variety of message area attributes are supported.  With them, you
    can define exactly what type of messages will be placed in what area.

    Private only        All messages entered in this area will be marked
                        "private," and cannot be read by other users.

    Public only         All messages in this areas can be read by all
                        users.

    Read-only           Messages in this area can be read by callers, but
                        only sysops and assistant sysops can enter new
                        messages.

    Anonymous           In an area marked as "anonymous," Opus will ask
                        the user to supply a pseudonym.

    Alias               In an area marked as "alias", Opus will use the
                        user's alias on messages from the user.

    EchoMail            Conference-type message bases are recognized. The
                        user will be told that the message will be
                        broadcast, and Opus will automatically do such
                        echomail-oriented processing as inserting an
                        "origin line" into the message.

    Inbound-only        Echomail messages are tossed into this message
                        area, but messages are never scanned out to other
                        systems from this message area. Useful for "read-
                        only" echomail conferences.

    Matrix messages     These are treated like FidoNet<tm> messages. The
                        user is asked where the message is to be sent, to
                        whom and to what address.

     
     
    OPUS V1.70 OVERVIEW                                          Page 29 
     
     
    Barricaded          Barricaded areas may have a special password(s)
                        associated with them so that only users who know
                        the password(s) get the specified privilege level
                        in that area. Barricaded areas may also have
                        special privilege levels associated with certain
                        users' names. By using this feature you can allow
                        users higher or lower privileges in certain areas.

    These attributes may be combined in any fashion. You can require all
    messages in your Matrix area to be private, or all EchoMail messages
    to be public. It is up to the sysop as to how message areas will
    behave.



    2.6 FILE TRANSFERS

    Opus supports four different types of file transfers: uploads,
    downloads, Matrix and file requests. These enable the sharing of
    public domain or "shareware" software among users and other bulletin
    board systems.



    2.6.1 UPLOADS

    Uploading is defined as a user sending a file TO a BBS. This lets
    users share programs they have written or collected.


    2.6.2 DOWNLOADS

    Downloading is defined as a user receiving a file FROM a bulletin
    board system. This allows a single point to serve as a "holding tank"
    for software that can be freely shared among users.



    2.6.3 MATRIX

    Matrix transfers are uploads or downloads between two Matrix systems.
    You can direct Opus to send a file to any other system in the Matrix.
    Opus will accept incoming Matrix files any time it is not busy.





    Page 30                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    2.6.4 REQUESTS

    File requests are another variant of Matrix transfers between two
    Matrix systems. You can direct Opus to obtain a file from any other
    system in the Matrix which accepts WaZOO file requests. Opus cannot
    initiate SEAdog-style "bark" requests (but will accept and process
    such requests -- see below).

    Opus will accept both WaZOO and "bark" file requests from other Matrix
    systems, if it has been setup to do so. Any system can initiate a
    WaZOO file request simply by sending a file with a ".REQ" file
    extension containing a list of the requested files.



    2.7 EXTENDED FILE TRANSFER PROTOCOLS

    Several transfer protocols are supported in Opus. These include
    Zmodem, Ymodem, Xmodem, Telink, and SEALink. Opus V1.70 also has 16
    "slots" available for installation of external protocols, at the
    sysop's discretion -- for example, Windowed Xmodem (WXmodem), Sliding
    Window Kermit, and YmodemG. These will be described more thoroughly in
    the file transfer section. The precise manner in which Opus interacts
    with external protocols is detailed in the Opus Technical Reference
    Manual; refer to that manual for the fine technical details.



    2.8 OEC FILE CAPABILITY

    OEC (Opus Embedded Command) files provide a world of customisation
    possibilities for you to explore. Opus Embedded Command files support
    both AVATAR and ANSI graphic codes as a user option. If you use Avatar
    graphic codes in files, Opus will send them to Avatar users, convert
    them into ANSI for ANSI users or strip them for TTY users.

    Through the use of an embedded command, you can make any support file
    branch to an external program. The sysop is responsible for ensuring
    that the program directs its output to the comm port. This feature
    allows multiple "Outside" features to be supported.

    Questionnaire information can be collected from within any OEC file.
    This can be used to log the activity of any displayed section of your
    bulletin board.

    You can insert a person's name, display a quote, date and time, etc.,
    within any OEC file. Virtually anything Opus knows about the user can
    be displayed at any point in the support files. Additional embedded
    commands allow you to make any OEC file a submenu. This is handy for
    things like multiple bulletins, interactive help systems, etc.

    You will find a more details on OECs in the section of this manual on
    Setting Up Opus. For the complete list of OECs and the OEC file
    mechanism, refer to the Opus Technical Reference Manual.

     
     
    OPUS V1.70 OVERVIEW                                          Page 31 
     
     
    2.9 ECHOMAIL ENHANCEMENTS

    Opus lets the sysop decide whether EchoMail SEEN-BY lines are
    displayed to the user. Few appreciate the unsightliness of this part
    of EchoMail, and Opus eliminates that problem. If you do not care for
    SEEN-BYs, Opus lets you disable their display on a privilege level
    basis.

    The display of extended addressing can be disabled. As more distinct
    addresses become available over the Matrix, more information will need
    to be embedded within the body of messages. Opus lets you control who
    can and cannot see this information.

    Opus automatically inserts its own origin line if a message area is
    marked as echomail. This lets other systems know which Matrix system
    originated the message and what software processed the mail.

    You can tell Opus to uncompress and toss compressed mail and EchoMail
    packets automatically. You do not have to declare an external event to
    extract compressed mail packets and toss EchoMail -- Opus does this
    for you.



    2.10 MATRIX/NETWORK MAIL INTERFACE

    Opus can receive mail at anytime. Matrix/Network transactions are not
    restricted to fixed time slots. You can also send mail to another Opus
    at anytime.



    2.11 OPUS OPERATING PHILOSOPHY

    The operating philosophy of Opus is based on the KISS principle:

                        -={ KEEP IT SIMPLE SYSOP! }=-

    Opus is very easy to use if you let the installation kit do its job. A
    sysop can lead a very satisfying life with the basic Opus
    installation. It will still be a superior system, requiring a minimum
    of maintenance. There are thousands of custom features available; each
    Opus board will probably look and act differently, but there is no
    guarantee that any of the customization methods will be easy or
    immediately apparent.

    It is best to start with a basic system and to customize things
    gradually after gaining experience with Opus. The difficult functions
    are always available, but never required. If you want to tailor your
    system to look and act a certain way, you can, any time. The rewards
    you reap are proportional to the amount of work you put into the
    system, and that can run into years if you let it.

    3.0 SETTING UP OPUS V1.70

    To set up a new Opus V1.70 system, or to convert from a previous
    version of Opus, refer to the separate installation manual.

    Having installed Opus V1.70, there are many ways to customise your
    shiny, new Opus system: the control file, the menu system, privilege
    levels and locks for access to message and file areas as well as menu
    commands, "sections" or "sigs", barricaded message and/or file areas,
    Opus embedded command (OEC) files, bulletins, special announcements,
    custom welcome files and caller expiration control to name but a few.
    These, and others, are dealt with in the following sections. Let the
    fun begin!



    3.1 THE CONTROL FILE

    The Opus control files (BBS.CTL) is the single best place to find ways
    of customising your system.

    Please refer to section 2 of the Technical Reference Manual for a
    detailed description of the many control file options which are
    available.



     
     
    SETTING UP OPUS V1.70                                        Page 33 
     
     
    3.1.1 CONTROL FILE MAINTENANCE

    The control file (BBS.CTL) can be split into separate sections for
    easy maintenance or separate compilation. This is especially handy on
    multiline systems where you do not want to have to alter more than one
    control file to add a new message area. On single line systems, it is
    also handy to be able to just produce the BBS.PRM file rather than
    also regenerating all the necessary system files for the message and
    file area definitions and the menu system files. You can also do
    separate compilations of:

        * the parameter file (BBS.PRM);

        * the file and message area system files (SYFILE.DAT, SYSMSG.DAT,
          NAME.FDX, NAME.MDX, NUMBER.FDX, NUMBER.MDX and ECHO.MDX); and

        * the menu files (eg ENGLISH.MNU).



    3.1.2 THE PARAMETER FILE

    To do a compilation of just the parameter (BBS.PRM) file you need to
    include the System Section, Language Section, Equipment Section,
    Matrix and EchoMail Section and Session Section of your control file
    in BBS.CTL. You may keep these different sections all in the one file
    or each in its own file.

    If you split the different sections into separate files, your BBS.CTL
    might contain just the following lines:

        include c:\opus\config\system.ctl
        include c:\opus\config\language.ctl
        include c:\opus\config\equipmnt.ctl
        include c:\opus\config\matrix.ctl
        include c:\opus\config\session.ctl

    Running NACL BBS would then produce a compiled BBS.PRM file.



    3.1.3 FILE AND MESSAGE AREA SYSTEM FILES

    To do a compilation of just the file and message area system files,
    you need to include the File Areas and Message Areas Sections of your
    control file. You may keep these different sections all in the one
    file or each in its own file. In either case, you must put your File
    Areas BEFORE your Message Areas or NACL will laugh at you ... loudly!

    There is also one other special requirement in this situation. You
    must add a PATH OVERRIDE <path\> line to the beginning of your area
    files. The path you define here should be the same as you defined for
    PATH SYSTEM in the System Section of your control file. If you do not
    do so, yep, you guessed it in one, NACL will laugh at you ... loudly!



    Page 34                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    If you split the File Areas and Message Areas Section into separate
    files, your AREAS.CTL file might contain just the following lines:

     include c:\opus\config\filearea.ctl
     include c:\opus\config\mesgarea.ctl

    Running NACL AREAS would then just produce the file and message area
    system files.



    3.1.4 MENU FILE(S)

    To do a compilation of just the menu file (eg ENGLISH.MNU), you need
    to include the Menu Section of your control file in a separate file
    (eg MENU.CTL).

    Running NACL MENU would then just produce the menu file(s). There is
    one gotcha though. The new compiled ENGLISH.MNU file will be in the
    directory from which you ran NACL. You need to move it to the
    directory defined with the LANGDIR option in the Language Section of
    your control file.



    3.1.5 ALL FILES

    To compile your whole system, your BBS.CTL file might contain the
    following lines:

        include c:\opus\config\system.ctl
        include c:\opus\config\language.ctl
        include c:\opus\config\equipmnt.ctl
        include c:\opus\config\matrix.ctl
        include c:\opus\config\session.ctl
        include c:\opus\config\filearea.ctl
        include c:\opus\config\mesgarea.ctl
        include c:\opus\config\menu.ctl

    or it might contain the following lines:

        include c:\opus\config\system.ctl
        include c:\opus\config\areas.ctl
        include c:\opus\config\menu.ctl

     
     
    SETTING UP OPUS V1.70                                        Page 35 
     
     
    or for a multiline system you might have two BBS.CTL files like this:

        711_401.CTL

        include c:\opus\config\sys401.ctl
        include c:\opus\config\areas.ctl
        include c:\opus\config\menu.ctl

        711_501.CTL

        include c:\opus\config\sys501.ctl
        include c:\opus\config\areas.ctl
        include c:\opus\config\menu.ctl



    3.1.6 MACRO SUBSTITUTIONS

    As if the ability to split the control file into its separate
    component section was not enough, you can also use macro substitutions
    in the control file. For example, your BBS.CTL might contain the
    following:

        Misc = c:\opus\misc
        Help = c:\opus\help
        Task = 01
        Port = COM2
        include c:\opus\config\system.ctl
        include c:\opus\config\areas.ctl
        include c:\opus\config\menu.ctl

    The macros defined above are then used like this in the separate
    control files:

        PATH MISC      $(Misc)\
        PATH SPANN     $(Misc)\
        USES PASSWORD  c:\opus\user$(Task).dat
        USES SCHED     c:\opus\sched$(Task).dat
        LOG FILE       c:\opus\opus$(Task).log
        OUTPUT         $(Port)

    NACL would make the macro substitutions and interpret the above lines
    as follows:

        PATH MISC      c:\opus\misc\
        PATH SPANN     c:\opus\misc\
        USES PASSWORD  c:\opus\user01.dat
        USES SCHED     c:\opus\sched01.dat
        LOG FILE       c:\opus\opus01.log
        OUTPUT         COM2



    Page 36                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    You can also use the macros in the include <filename> parameters like
    this:

        Node = 401
        include c:\opus\config\sys$(node).ctl
        include c:\opus\config\areas.ctl
        include c:\opus\config\menu.ctl



    3.2 THE MENU SYSTEM

    The Opus V1.70 menu system is extremely flexible, especially with the
    addition of the six CUSTOM menus, the ability to use alternative
    menus in specified areas and the ability to replace the normal Opus
    menus. Menu prompts may now also be customised!

    Please refer to section 3 of the Technical Reference Manual for a
    detailed description and list of the many menu options which are
    available and how they may be implemented.



    3.2.1 CUSTOMISING MENU PROMPTS

    You customise the menu prompts by specifying the prompt you wish to
    use in quotation marks after the name of the menu in menu section of
    the control file. For example:

        MAIN MENU   "Sentry Main Menu"



    3.2.2 CONTROLLING ACCESS TO MENU COMMANDS

    A caller's access to menu options may be controlled by using one of
    the Opus privilege levels (Hidden, Sysop, AsstSysop, Clerk, Extra,
    Favored, Privil, Worthy, Normal, Limited, Disgrace, Twit) and by
    setting locks on the menu command to which callers will need the
    corresponding key(s).

    The format is:

        MENU_COMMAND !<locks> "<description>"

    The first character of the description filed is used by Opus for the
    command letter that the caller should type to execute the command. Be
    careful not to use the same letter twice in the same menu or Opus will
    only ever let the caller execute the first command with the common
    command letter. Note that the use of locks on the command is optional,
    whereas a privilege level must be specified.

     
     
    SETTING UP OPUS V1.70                                        Page 37 
     
     
    For example, the file download command could require the caller to
    have NORMAL access or above and also the key for lock X. This is what
    the entry in the control file would look like:

        F_DNLD   Normal   !X   "Download a file"

    Do not overlook the fact that privilege levels for some menu commands
    may be overidden by other control file options. For example, in the
    definition of a file area you can specify the DOWNLOAD PRIV and the
    DOWNLOAD LOCK options which will override the privilege and locks you
    have set on the menu command FOR THIS AREA ONLY. There are other
    similar control file options which will override menu command
    settings, please refer to section 2 of the Technical Reference Manual
    for the full list of such options.



    3.2.3 DISPLAYING OEC FILES

    Bulletin or help files may be shown to callers by adding the _SHOW
    menu command to any menu. You can add as many _SHOW menu commands to
    the same menu as you wish. For example:

        _SHOW    Twit      "Software Bulletin" = c:\opus\misc\sware
        _SHOW    Twit      "Hardware Bulleton" = c:\opus\misc\hware
        _SHOW    Disgrace  "Editorial"         = c:\opus\misc\edtorial
        _SHOW    Twit      "? Help"            = c:\opus\misc\menuhlp

    Note that although you do not use a file extension on the name of the
    file to be shown, it must be an OEC file with either a .BBS or .GBS
    file extension. The .BBS files are preferred because if you use Avatar
    graphics commands in them, Opus will send Avatar to callers who
    support Avatar, and send ANSI graphics commands to callers who support
    ANSI or strip the commands for TTY callers who support neither Avatar
    nor ANSI graphics commands. A .GBS file is only shown to callers who
    support ANSI and is therefore largely superseded. Refer to section 4
    of the Technical Reference Manual for a detailed description and
    listing of OEC commands.



    3.2.4 RUNNING EXTERNAL PROGRAMS

    External programs  may also be run
    from the menus. For example, here is a sysop menu you could implement:

     %
     SYSOP MENU
        SYS_MAIL   Sysop   "Matrix setup"
        _OUTSIDE   Sysop   "Events"       = DOS c:\opus\oevent.exe /a
        _OUTSIDE   Sysop   "Outside"      = EXIT 12
        _MAIN      Sysop   "Quit"
        _SHOW      Sysop   "? HELP"       = c:\opus\hlp\syshelp
     END Menu
     %


    Page 38                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    Choosing the "Events" command would run the OEVENT.EXE (Opus Event
    Manager) program with the /a command line. Choosing the "Outside"
    option would cause Opus to exit to the batch file from which you run
    Opus (NERF.BAT) with a DOS errorlevel of 12. Your batch file should
    trap that errorlevel and act on it. See Appendix A for a sample
    NERF.BAT batch file.

    Refer to section 3 of the Technical Reference Manual for details of
    the various different methods of implementing the _OUTSIDE program
    option. Further discussion of these methods may also be found in
    section 7 of the Technical Reference Manual.

    For the correct method  of implementing external file protocols (ie,
    so that Opus will keep track of caller uploads and downloads and daily
    limits), refer to section 7 of the Technical Reference Manual.



    3.2.5 GLOBAL MENU COMMANDS

    Global menu commands (those with a leading underscore character) may
    be included in any menu. For example, in the message menu you could
    add the following:

        _FILE               Disgrace      "Jump to File Menu"

    to jump to the file area menu, and in the file area menu you could add
    the following:

        _MESSAGE            Disgrace      "Jump to Msg Menu"

    to jump to the message area menu -- all without having to go through
    the main menu!

    Refer to section 3 of the Technical Reference Manual for the full
    listing of global menu commands.



    3.2.6 AUTOMATIC ZMODEM UPLOAD

    Opus can be configured to receive Zmodem uploads automatically without
    the caller having to type UZ (Upload Zmodem).

    The Zmodem protocol states that the uploading software should start by
    sending 'rz\r', in which the '\r' stands for carriage return. Thus if
    your menu choice for upload is 'R' (as in RUpload Zmodem), the caller
    need type nothing, he/she just has to start sending the file(s) and
    the Zmodem protocol will let Opus know about it.

    You can add the 'R' option and keep the old "U)pload" option at the
    same time. Opus can handle multiple menu items with the same meaning.

    Note that this may not work right for the callers with Hotflash. After
    Opus receives the 'r', it will clear its menu buffer (thus discarding
     
     
    SETTING UP OPUS V1.70                                        Page 39 
     
     
    the 'z' and the CR) and ask what protocol you want. With all other
    types of menu, automatic Zmodem uploads work well.

    There is one last gotcha: if the caller has set a default file
    protocol, and that protocol is not Zmodem, this will not work!



    3.2.7 SUPERSEDED MENU COMMANDS

    Some menu commands from Opus V1.1x versions have been superseded. Most
    notably, the configuration menu commands which dealt with things about
    the caller have been transferred to the history menu.

    Refer to section 3 of the Technical Reference Manual for the full
    listing of menu commands and details of which menu commands may appear
    on which menus.



    3.2.8  ALTERNATIVE MENUS

    There is truly no end to the flexibility of the Opus Menu System. For
    each area, for very special purposes, you can define an alternative
    menu file to use just for that area. With alternative menus, you can
    create a special personality or command set for a particular area.

    To implement this feature, copy your current menu section from your
    control file to a separate file and call it, for example, MENU001.CTL.
    Use your trusty wordprocessor to customise those menu(s) that you wish
    to be different.

    Now compile just that menu file by running NACL MENU01. NACL will
    produce a new ENGLISH.MNU file in the directory from which you ran
    NACL (so do not run NACL in the same directory as your existing
    ENGLISH.MNU file!). You should now rename your new ENGLISH.MNU file to
    ENGLISH.001.

    Wait a minute ... you now need to edit the MENU <number> option in the
    relevant message and/or file area definitions in your control file to
    reflect the particular menu number you wish to be used for those
    areas. For example, you may wish to use the modified menu only in
    Message Area 20. You would modify the message area 20 definition like
    this:

        AREA  0020  SPECIAL
        MENU  001
        etc

    Recompile your control file with NACL (or just the file and message
    area definitions section of the control file -- refer to section 3.1.1
    above for how to do this). Now when Opus switches to that area, it
    would use ENGLISH.001 instead of ENGLISH.MNU.

    Note that if you support more than one language, you would have to


    Page 40                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    create an alternative menu with the same number extension for each
    language you support.

    You will generally not need to use this option for most situations.



    3.2.9  ASCII MENUS

    Menu system not flexible enough for you? Yep, you guessed it. There is
    more. With Opus V1.70 you can also implement what are somewhat
    misleadingly referred to as ASCII menus. These menus are really custom
    menus which you can use to replace the normal Opus Main, Config,
    History, Section, Sysop and six Custom menus. Opus rather cleverly
    uses smoke and mirrors to achieve this replacement.

    The ASCII menus feature was added so that sysops could replace the
    fairly quick-displaying Opus menus with those long, slow graphics
    menus that some sysops and callers prefer [climbing off soapbox].

    Several control file options should be set if you are going to use
    this option. In the Session Section of your control file, uncomment
    the LOGON ASCIIMENU option (and make sure it is adequately described
    in your CONFHELP.BBS file). New callers will now be given the option
    of using ASCII menus and the option will also now appear on the
    configuration menu.

    You also need to uncomment each of the following options in the
    Session Section of your control file for which you are going to
    define a corresponding ASCII menu file:

            USES MainMenu     MAIN
            USES ConfMenu     CONF
        %   USES SectMenu
            USES SysopMenu    SYSOP
            USES HistoryMenu  HIST
        %   USES CUSTOM1Menu
        %   USES CUSTOM2Menu
        %   USES CUSTOM3Menu
        %   USES CUSTOM4Menu
        %   USES CUSTOM5Menu
        %   USES CUSTOM6Menu

    Note that you do not specify a file extension for your replacement
    menu files. These files follow the normal OEC (.BBS/.GBS) file
    standard, so you can use any of the Opus Embedded Commands in them!
    Refer to section 4 of the Technical Reference Manual for a full
    description of OEC files and the complete list of OECs available.

    Now for the smoke and mirrors part. When a caller chooses the ASCII
    menu option at logon, the caller gets expert help automatically
    selected ... ahah, no normal Opus menus are shown, only the ASCII
    menus which you have defined. Of course, a caller can choose their
    help level from the configuration menu and might decide to set it to
    regular for the one line command letter prompts. If the caller selects
     
     
    SETTING UP OPUS V1.70                                        Page 41 
     
     
    novice help, the caller will get the ASCII menus followed by the
    normal Opus menus. Smoke and mirrors are not that good!



    3.2.10 OEC MENU PROMPTS

    A new Opus Embedded Command widget in Opus V1.70 especially designed
    for menus is ^FM. This OEC simulates the current Opus (or your
    customised) menu prompts so that it looks to the caller as if the
    caller is still inside Opus and not inside one of your OEC files
    which was called from the relevant menu.

    Refer to section 4 of the Technical Reference Manual for the complete
    listing of the many OECs available. Some examples of the usage of OECs
    may be found in the Implementing OEC Files section of this manual.



    3.2.11 MENU SAFETY FEATURE

    If the Sysop puts a jump to another menu in a menu, but never defines
    that other menu, callers used to be lost in limbo. Now Opus V1.70 will
    check to make sure that there really is a menu to go to, and if not,
    will log the error, tell the caller to tell the Sysop about it, and
    then send the caller to the MAIN menu.



    3.3 BOMBING RUNS

    Check that you have your full complement of HE bombs on board and that
    the bomb bay doors have been properly secured, ooops, wrong document
    file. [Editor's note: this gag is probably copyrighted / patented /
    trademarked by Jon Sabol.]

    Opus lets you do message bombing runs (to use the old Fido-talk) or
    "carbon copies" (to use SEAdog-talk). You can enter the one message
    and then send it to a bunch of other people. You might like to stop
    here for a few minutes and imagine just how unpopular you could
    quickly become with Network Hosts if you indiscriminately use bombing
    runs for Matrix messages ... <buzz>, sorry, wrong -- you really cannot
    imagine.

    To use this feature you enter a message normally and save it. You then
    choose the Forward command (the MSG_FORWARD menu command) and Opus
    will ask you:

        * whether to use the same message area;

        * whether you wish to delete the original message;

        * whether to make the new message(s) private;



    Page 42                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


        * (if you are forwarding the message to the matrix message area or
          in the matrix message area, other questions may be asked
          depending on the MESSAGE EDIT ASSUME and ASK settings in your
          control file);

        * whether you wish to make a bombing run (yes, you do);

        * (if in the matrix message area, you may be asked for the matrix
          address of the addressee -- ignore this by pressing ENTER);

        * for the addressee (ignore this, type something to keep Opus
          happy - if you answered private above, it must be someone in
          your user file);

        * whether you wish to use the original subject line;

        * for the route file!

    The "route file" must be in the following format:

        Zone:Net/Node.Point First_Lastname <mode>

    where <mode> is optional and may be one of -c (crash) or -h (hold).
    Note that each part of the person's name must be separated from the
    other by an underscore. If you are logged in from the from the
    keyboard, you can specify CON for the route file and Opus will let you
    key in one Z:N/N.P F_L entry at a time. Press ENTER to finish.



    3.4 IMPLEMENTING OEC FILES

    Opus Embedded Command (OEC) files probably offer room for the most
    creativity. You can use embedded commands, video and cursor commands
    to create lavish widgets for callers.

    Entering the control codes for Opus Embedded Commands can be tricky
    depending on the facilities offered by your favourite wordprocessor
    for entering. There are some tools available that will make this task
    somewhat easier for you: OEC Compilers and a program called CTRLCODE.

    OEC compilers let you use "English" like commands to create your OEC
    files. You then "compile" these plain text files into the OEC files.
    The compiler translates the English expressions into the relevant
    control codes (correctly with a byte of luck).

    Grizzled Opus veterans will probably prefer to enter the control codes
    directly. Even this task is made considerably easier with the CTRLCODE
    program. This program lets you create a text file containing the caret
    sign "^" (the "^" sign is located above the number 6 on the top row of
    your keyboard) followed by the appropriate letter. So, you type ^X
    which is two text characters, then run CTRLCODE which will convert
    those two characters into the corresponding single character control
    code. Follow that?  Sorry, you really do have to be a grizzled Opus
    veteran <grin>.

    Example uses of only some of the many OECs available are set out in
    the following sections. The sections only just begin to scratch the
    surface when it comes to OECs. For the complete listing of OECs and
    explanation of OEC files, refer to section 4 of the Technical
    Reference Manual.



    3.4.1 QUOTATION OF THE MOMENT

    You can set Opus up to display a quotation of the moment to callers
    by, for example, embedding ^F^A in your WELCOME file (to show the
    quotation at logon) or your BYEBYE file (to show the quotation at
    logoff). If you are going to use the welcome or byebye files, do not
    forget to define the USES WELCOME and USES BYEBYE options in the
    Session Section of your control file (BBS.CTL).

    To use the quotation option, you must also have defined a quotation
    file with the USES QUOTES option in the Session Section of your Opus
    control file. For example:

        USES QUOTES c:\opus\misc\quotes

    The format for the quotation file is fairly simple. It is a normal
    text file. Each quotation is separated from the other by a single
    blank line. Here is a sample:

        Sex is hereditary. If your parents never had it, chances are you
        won't either.
        JOSEPH FISCHER

        Real knowledge is to know the extent of one's ignorance.
        CONFUCIUS

        A committee is a body that keeps minutes and wastes hours.
        W.G.P.

        A fool says "I can't";
        A wise man says "I'll try".
        ANON

    You could also make the quotation of the moment an option off one of
    your menus.

        _SHOW  Disgrace  "Quotes" = c:\opus\misc\quote

    And QUOTE.BBS would contain:

        Quotation of the moment:

        ^F^A

        ^A

    3.4.2 PASSIVE QUESTIONNAIRES

    Opus allows you to implement questionnaires in OEC files. Here is a
    sample questionnaire using OECs followed by an explanation (line nos
    have been added for the commentary that follows only):

             the caller's answer.

    3.4.3 ACTIVE QUESTIONNAIRES

    As well as "passive" questionnaires, the Opus Embedded Commands also
    allow you to create "active" questionnaires. That is, questionnaires
    which ask questions or perform actions based on the caller's answer to
    the previous question. Here is a sample questionnaire using OECs
    followed by an explanation (line nos have been added for the
    commentary that follows only):

    00   ^K
    01   ^PNTX
    02   ^OOc:\opus\misc\tennis

    11   ^OUY a. 1900     b. 1939     c. 1942      d. 1946
    12   ^ORABCD|
    13   ^OMAnswer
    14   ^OUB
    15   ^OUB Correct!  You will now have access to the Tennis
    16   ^OUB EchoMail message area. Type 40 or DEUCE at the
    17   ^OUB Message Menu Change Area prompt.
    18   ^OUB ^PAT ^OQ
    19
    20   Wrong!
    21   ^PAX ^OQ


    Line 00: Turn off that pesky more prompt.

    Line 01: If the caller does not have the keys specified by ^PN<keys>
             (here the T key) sees rest of file (see below for
             significance of T).

    Line 02: See line 01 for explanation.

             NOTE: ^PNTX would not work -- that means if the caller does
                   not have the T _AND_ X keys, see rest of file.

    Line 03: ^OO<filename> opens an answer file for the caller's responses
             and for the information collected in line 04, 06 and 14 for
             the sysop's future reference.

    Line 04: ^OP posts the caller's name, city/state and the date/time of
             the call to the answer file declared in line 03.

    Line 05: ^F^F displays the caller's first name for the personal touch.
             ^OR<chars> defines the valid responses to this question. In
             this example they are Y, N or ENTER.

    Line 06: ^OM<string> posts the caller's answer to a multiple choice
             question in the answer file. <string> optional, but very
             handy for reminding the sysop with short-term memory loss
             what the question was that goes with the answer.

    Line 07: ^OU<char> will execute if, and only if, the caller's
             previous response matches the specified character.
             ^OQ terminates the OEC file.

    Line 08: As for line 07, except that it caters for the ENTER response.

    Line 09: As for line 07, except that it caters for a Y response.

    10 - 12: More of the same.

    Line 13: ^OR<chars> see line 05 for explanation.

    Line 14: See line 06 for explanation.

    Line 15: See line 07 for explanation.

    16 - 18: More of the same.

    Line 19: This line executes if, and only if, the caller's response
             was that specified by ^OU<char>; in this case B (the correct
             answer).
             ^PA<key> adds the specified key to the caller's keys; in this
             case the key T is added to give the caller access to the
             Tennis echo.
             ^OQ terminates the OEC file.

    Line 20: Ah yes, some people will try anything!

    Line 21: But only once! See line 19 for explanation; in this case the
             caller is given the X key to prevent any further attempts
             (see line 02) to answer the question correctly. The ^OQ is
             probably not needed, but I like working with safety nets.

      ANSWER: B



    3.4.4 SENDING A MESSAGE TO THE NEXT CALLER

    You can allow callers, even on single line systems, to send a message
    to the next caller by using the ^FL OEC. Opus will not ask the caller
    which task to send the chat message to; it selects the current task.

    This OEC could be put in your BYEBYE file (make sure you have defined
    this file with the USES BYEBYE option in the control file) like this:

        Leave a message to the next caller? [y,N]
        ^ORYN|
        ^OY ^FL

    Then the caller could leave a CHAT## to the current task number and
    hang up. The next caller comes on line and as soon as that caller hits
    a menu, Opus displays the message from the last caller.





    Page 48                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    3.4.5  OEC FILE STACKING

    The ^OA<file> OEC starts displaying <file>. When <file> is done, Opus
    returns to the current file at the current position. You can stack
    this command. Here is an example:

        file1.bbs contains:                   file3.bbs contains:
              This is file1.bbs                     This is file3.bbs
              ^OAfile2                              ^OAfile4
              This is file1.bbs                     This is file3.bbs
              ^OAfile5
              This is file1.bbs               file4.bbs contains:
                                                    This is file4.bbs
        file2.bbs contains:
              This is file2.bbs               file5.bbs contains:
              ^OAfile3                              This is file5.bbs
              This is file2.bbs


    The above sequence of OEC files would display to a caller as follows:

        This is file1.bbs
        This is file2.bbs
        This is file3.bbs
        This is file4.bbs
        This is file3.bbs
        This is file2.bbs
        This is file1.bbs
        This is file5.bbs
        This is file1.bbs


    This OEC uses a doubly linked list so the limitation is how much
    memory your system can find, but it is recommended that it be kept
    down to 4-5 deep.

    Another method of OEC file stacking is by using the ^OX OEC. This OEC
    records the current position in the current file, jumps to <position>
    (position is the number of bytes from the beginning of the file) and
    when ^OY is encountered, Opus returns. Here is an example:

        This is the beginning of MAIN Menu....
        ^OX0105
        And this is back to MAIN.BBS
        ^OQ
        This is some point further along in Main MENU
        ^OX0226
        This is back to mid-point further along in MAIN
        MENU
        ^OY
        This is yet further along in MAIN MENU


     
     
    SETTING UP OPUS V1.70                                        Page 49 
     
     
    The above example would display as follows:

        This is the beginning of MAIN Menu....
        This is some point further along in Main MENU
        This is yet further along in MAIN MENU
        This is back to mid-point further along in MAIN
        And this is back to MAIN.BBS


    This OEC can be stacked up to 10 levels deep.



    3.4.6 COMMAND BUFFER STUFFING

    The ^OG<command> OEC stuffs commands into the command buffer and quits
    the OEC file. You may use any commands available from the current
    menu. For example, if you have an OEC that ends with ^OGG, Opus quits
    the OEC file and starts the logoff procedure. You can also have it go
    to the download, upload, statistics, or any of the codes that are
    valid for the CURRENT menu. You can set up a fairly complex script via
    stacked commands, using either Escaped Hex codes or plain ASCII.

    Here is a script that you might use as a "fail-safe" to clear graphics:

        _SHOW     Twit  "If_All_Else_Fails" = c:\misc\bomb

        BOMB.BBS  <ESC>10f1 C V P H N Q

                  (Main Menu, Change Menu, Video/Plain, Help/Novice,
                  Quit to Main menu)

    Suppose at the end of an OEC file off your File Menu which listed
    "MY_LIST.BBS" you included:

        Download this file?

        Z)modem
        Y)modem
        X)modem
        K)ermit
        N)one
        ^ORZYXKN|
        ^OUZ dz my_list.bbs
        ^OUY dy my_list.bbs
        ^OUX dx my_list.bbs
        ^OUK <ESC>5004 k my_list.bbs
        ^OUN ^OQ
        ^OU| ^OQ

    Opus starts the download with the right protocol if a caller wants to
    download the file. You can also use the Full Tilt Boogie (FTB) menu
    commands by preceding them with an escape. What you are doing is
    stuffing the command buffer with keystrokes. If you send Opus off to
    do something illegal, because of privileges or whatever, it will be


    Page 50                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    handled just as though the caller were pressing the keys.

    The full list of FTB commands is listed in section 4 of the Technical
    Reference Manual.



    3.4.7  REGULATING PEAK TIME CALLER ACCESS

    To have Opus only allow those callers with a privilege level of
    Favored or higher to log on during specified hours, create two WELCOME
    files, a standard one named WELCOME1.BBS and a special one named
    WELCOME2.BBS that has the following at the beginning:

    00  ^L
    01  ^PBF ^OSwelcome1
    02  ^PBF ^OQ
    03
    04  I'm sorry, but this system runs restricted access between the
    05  hours of {start-time} and {end-time}.
    06
    07  Please call back after {end-time}
    08
    09  Thank You, THE SYSOP.
    10
    11  ^F^N


    Line 01: Clears the screen (aesthetics again)

    Line 02: If caller's privilege is below Favored, skip this line.
             Callers at or above Favored are shown the normal WELCOME
             file.

    Line 03: Quit this OEC file now for Favored callers.

    04 - 10: Message for callers below Favored.

    Line 11: Hang up on callers below Favored.


    Then setup an informal external event to run at {start-time} that
    exits with a DOS errorlevel of, say, 50 which is trapped by your
    NERF.BAT file like this:

        IF ERRORLEVEL 50 GOTO REST_ACCESS
        [etc]
        :REST_ACCESS
        COPY WELCOME2.BBS WELCOME.BBS
        GOTO START_OPUS


     
     
    SETTING UP OPUS V1.70                                        Page 51 
     
     
    and at {end-time} run another informal external event that simply
    exits with a DOS errorlevel of, say, 49 which is trapped by your
    NERF.BAT file like this:

        IF ERRORLEVEL 49 GOTO REST_ACCESS
        [etc]
        :NORM_ACCESS
        COPY WELCOME1.BBS WELCOME.BBS
        GOTO START_OPUS

    For a commented, sample NERF.BAT file refer to Appendix A of this
    manual. For information on scheduling informal events, refer to the
    section of this manual which describes the Opus Event System.



    3.5 EXTERNAL PROGRAMS

    External programs provide lots of help in customising your Opus CBCS.
    Here are a few which were available at the time of publication:


      CAYENNE   ... a program to de-compile your Opus control file, also
                    used in conversions from the previous Opus version

      CONFILE   ... a program to convert the old FILES.BBS file listings
                    into the Opus V1.70 files database

      DOORMAGIC ... a program to create various "door" control files for
                    running "outside" or "door" programs written for other
                    BBS software

      NACL      ... a program to compile your Opus control file

    3.6 MESSAGE AREAS

    Message areas and the method of storing messages in Opus V1.70 are the
    same as in previous versions of Opus. The setting up and maintenance
    of message areas is discussed in the following sections.



    3.6.1 CHECKLIST FOR NEW MESSAGE AREAS

    Checklist for setting up a new message area:

       * Create a subdirectory for the message area;

       * Edit your BBS.CTL file to include the new message area definition
         in the Message Areas Section;

       * Run NACL against your modified BBS.CTL file (refer to the section
         of this manual on control file maintenance for the gory details).



    3.6.2 SAMPLE MESSAGE AREA DEFINITION

    Message area definitions are found in the Message Areas Section of
    your control file. Here is a sample message area definition which
    lists all the possible control file options for such a definition:

        %    APPLICATION    <string>
        %    EXTERN RENUM
        %    EXTERN MAILCHECK
        END AREA


    You guessed it, please refer to section 2 of the Technical Reference
    Manual for a detailed description of each of the control file options
    in the sample message area definition above.

    NOTE: In pre-V1.70 Opus versions, areas had to be numbered
          consecutively. If you skipped a number, all higher-numbered
          areas were invisible to callers; although they were still
          accessible, they did not appear on the Opus-generated area
          change list.

          This does not apply to Opus V1.70. All message areas will show
          up on the Opus-generated area change list EXCEPT where the
          caller does not have thee required privilege level or key(s).




    Page 54                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    3.6.3 AREAINFO FILES

    You can put an AREAINFO.BBS (or AREAINF~.BBS file for systems which
    support more than one language) file in each message area directory.
    This file will then be shown to every caller each time the caller
    enters the relevant message area.

    You could use the file for displaying the rules of that specific
    message areas. It is particularly useful in trading post echomail
    areas for warning callers not to place commercial advertisements, for
    example.

    As the file is a normal OEC file, you can stop it being shown to your
    trusted callers over and over again by using OECs to only show it to
    those with a certain access level or below or without certain keys.



    3.6.4 SMART RULES FILES

    There is a "smart" menu command which you can use to allow callers to
    display the rules file in message areas. You put the MSG_RULES menu
    command on your message menu and it will only show up when a RULES.BBS
    (or RULE~.BBS file for those systems which support multiple languages)
    file is found in the relevant message area directory!

    In addition, Opus will automagically show the rules file, if it
    exists, to any caller whose lastread message pointer for the area is
    zero.

    In file areas, you need to define the rules file in the file area
    definition using the RULES control file option. The file will only be
    shown to those callers who have never before entered the relevant file
    area (you can cause it to display again by deleting the LFILE.DAT file
    in that file area's download directory -- that file stores who was in
    the file area and when for use by one of the Opus Embedded Commands).

    Refer to section 2 (areainfo and rules files) and section 4 (OECs) of
    the Technical Reference Manual for further details.



    3.6.5 MESSAGE AREA MAINTENANCE

    Messages are stored in individual files. Message #1 is in a file
    called "1.MSG", for example.

    Large gaps between message numbers can cause big online delays. There
    are several public domain message renumber utilities. You should
    renumber message areas regularly.

    One thing you should also do occasionally: reorganize your physical
    drive. Several utilities are available (eg, Optimize, DOG, SD) to do
     
     
    SETTING UP OPUS V1.70                                        Page 55 
     
     
    such things. They are handy and highly recommended. In technical
    terms, these programs "de-fragment" your disk. Run them once a month
    or so.



    3.7 FILE AREAS

    Probably one of the biggest changes between Opus V1.70 and previous
    Opus versions is the fact that V1.70 now uses a database for keeping
    track of files instead of the plethora of individual FILES.BBS files
    that the grizzled veteran Opus sysop either learned to love or loved
    to hate.

    Despair not!  Utilities have been provided to convert FILES.BBS files
    into the new files database AND to unconvert the new files database
    into FILES.BBS files AND to manage the new files database.



    3.7.1 THE FILES DATABASE

    The Opus V1.70 files database is actually a system of three files. One
    file contains all the information about what files you have on your
    system (FILESBBS.DAT), one is the index to all the file names on your
    system (FILESBBS.NDX), and one is an index into the first file in each
    file area (FILESBBS.ADX).

    Here are a few of the highlights of the new files database:

    * You can specify where in each file area listing new files will be
      added either when U)ploaded or H)urled by inserting a greater than
      sign > in the listing for an area. Normally new files are appended
      to the end of the listing for an area.

    * You can specify full paths to files if they are not in the default
      directory for that file area. This will probably be of benefit to
      those sysops who run CD-ROM drives on their systems.

    * Who uploaded the file and when is stored with each file.

    * The file date and time is preserved when files are received via
      Zmodem transfers. The search for new files will look at the upload
      date/time, but the callers will see the actual file creation time when
      they do a F)iles listing.

    * When a caller does a L)ocate, or searches for a string with the F)iles
      command, they also optionally (sysop configurable by privilege) get
      an additional line of information including who uploaded the file
      and when.

    * The F)iles display has been modified so it does a word-wrap for
      callers who have screens wider than 60 characters. File descriptions
      may be up to 256 characters long.



    Page 56                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    * Each individual file can have its own download privilege and locks.
      Normally they will be set to the area's download privilege and
      locks, unless you have set the NEW PRIV option in the file area
      definition. You can also override the privilege and locks on a file-
      by-file basis.

    * If a caller tries to download a file from an area, and the file does
      not exist in that area, Opus will look for the file in all the other
      areas to which the caller has access and, if it finds it, the
      download will continue as normal!

    * Opus will not allow callers who have privilege below ASSTSYSOP to
      upload duplicate file names anywhere unless the DUPES option has
      been specified in the file area definition.

    * If a caller has never been in a file area before, and the sysop has
      defined a RULES file in that area's definition, Opus will show the
      caller that file. The idea behind this is that you might want to
      have some areas that have minimal restrictions on them, like an area
      that has nude GIF files in it. You could ask "Are you over 18?" and
      if the answer is no, send the caller somewhere else using OECs.

    * If you implement the FREE control file option in a file area
      definition, then Opus will not consider files downloaded from that
      area to be part of the callers upload:download ratio or daily
      download limit. This should work properly even when callers are
      downloading a batch of files from different areas. The only problem
      is that Opus will not know which files are "free" and which are not
      when reading the log file produced by external protocol drivers. It
      will add the file sizes to the total downloads and daily downloads
      when using an external protocol.



    3.7.2 CONVERTING TO THE FILES DATABASE

    You convert your old-style FILES.BBS file area listings to the new
    files database by running the CONFILE program.

    Please refer to the documentation supplied with CONFILE for a blow-
    by-blow description of this procedure.



    3.7.3  CHANGING FILE AREA NUMBERS

    What do you do when you want to move a particular file area to a
    different area number? For example, you want to make your current
    games files area which is area 15 into a new area 88. You have a lot
    of typing to do, right? Wrong. John Valentyn sent along this recipe
    just for you:

     
     
    SETTING UP OPUS V1.70                                        Page 57 
     
     
        * Run UNCON to take all the file descriptions for area 15 from the
          files database to create an old-style FILES.BBS file for you;

        * Edit your control file (BBS.CTL), changing file area 15 to file
          area 88;

        * Run NACL against a copy of your control file that includes the
          Message and File Area Sections (refer to the section of the
          manual dealing with control file maintenance for more details);

        * Run OFARE, which will see that area 15 has been deleted and that
          area 88 is a new area, and will merge the FILES.BBS for area 88
          back into the database.



    3.7.4 SETTING UP NEW FILE AREAS

    Checklist for setting up a new file area:

       * Create a download subdirectory for the file area -- the download
         subdirectory contains the files you want to make available to
         your callers;

       * Copy the relevant downloadable files into the download
         subdirectory;

       * As necessary, create an upload and/or private upload and/or keyed
         upload directory for the file area -- the upload subdirectory/ies
         is/are the hold any files that callers might send to you;

       * Create an old-style FILES.BBS file listing which includes the
         descriptions of the files for the new file area -- the FILES.BBS
         file is a normal text file which contains the filenames beginning
         in column 1, followed by a space character, followed by the
         description of the file; comment lines must be indented at least
         one space character or they will be treated as filenames.

         There is also an EFW (environmentally friendly widget) bonus
         with the new files database -- an "alternative file path" for
         pointing to files that are not in the relevant file area
         directory, but are in another directory elsewhere on your
         system. Why EFW? It saves you hard disk space! To take advantage
         of this EFW, you put the full path to the file in the FILES.BBS
         file in addition to the filename, for example:

         z:\file\thisfile.zip

         Folks with CD-ROM drives may also like to take advantage of the
         fact that you can also put the full path to a file in the
         FILES.BBS file, so that when it is converted in the files
         database, the file path will be correct.



    Page 58                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


       * It is a good idea to leave 4 lines at the beginning of the new
         FILES.BBS listings so that the HiTech menus do not leave the
         topmost two or three lines of the listing on the screen -- in
         fact, this is a feature and not a bug. The first few lines are
         reserved for the a file area heading which is not erased each
         time the screen scrolls;

       * Edit your BBS.CTL file to include the new file area definition in
         the File Areas Section of the control file;

       * Do NOT forget to include an upload area number in your file area
         definition or you will experience this problem:

         > Also, I have uploaded files going into a particular
         > directory. The files go there, but when I do a new
         > files scan, they are listed in the area the caller was
         > in when the file was uploaded. In the area the caller
         > uploaded, the file and description are listed, in the
         > upload area, the file without a description are also
         > listed.

         UPLOAD PATH H:\NEWFILES\    <-----------------| Path
         UPLOAD AREA 31              <-----------------| Area #

       * Run NACL against your modified BBS.CTL file (refer to the section
         of this manual on control file maintenance for the gory details);

       * Run OFARE to update the files database.



    3.7.5 SAMPLE FILE AREA DEFINITION

    File area definitions are found in the File Areas Section of your
    control file. Here is a sample file area definition which lists all
    the possible control file options for such a definition:

    3.7.6 FILES DATABASE MAINTENANCE

    When a caller uploads a file, Opus will automatically put the file into
    files database.

    To add, delete or move files from the files database, or to edit the file
    descriptions, use the Opus File Area Manager (OPUS-FAM) program. Uhuh,
    please refer to the documentation that comes with OPUS-FAM for full
    details of this procedure. OPUS-FAM will also run in batch mode to
    produce file listings for file request lists (see below).

    You can also use Opus itself to "adopt" files which are not listed in
    the database, "orphan" files that are listed in the database, and
    "hurl" files from one area to another INCLUDING across physical
    drives! Yep, go check out section 3 of the Technical Reference Manual
    for the appropriate menu commands to include on your file menu.

    If you have other programs that need access to the old-style FILES.BBS
    file listings, use the UNCON program. UNCON with no parameters will
    regurgitate FILES.BBS in all areas, or you can put a list of areas on
    the command line and only those areas will get new FILES.BBS listings.
    UNCON.EXE will rename any existing FILES.BBS to FILES.BAK before
    writing the new FILES.BBS.

    To do minor, automatic maintenance there is OFARE. OFARE should be run
    as part of your automatic housekeeping like renumbering messages. It
    performs a number of functions, including re-packing the database as
    new files are added, expanding wildcard listings in the database to
    reflect any new files that have been added or deleted, eliminating
    files that have been deleted from the database and, optionally,
    eliminating any "Missing" files from your database. Here is a sample
    batch file:

         REM Sample nightly housekeeping
         REM Pick up any new files and remove deleted and missing files
         ofare /m

         REM Save the old files database in case of trouble
         pkzip -mex oldfiles filesbbs.o*

         REM Update FILES.BBS to match the database
         uncon 1 2 3 4 5 6 7 8 10

         REM Produce the FILES lists
         opus-fam -l

    3.8 BARRICADED MESSAGE AND FILE AREAS

    You can "barricade" message and file areas in Opus so that a caller
    needs another password to get into the area. This password not only
    admits the caller to the area, but is associated with a privilege
    level which the caller will have ONLY while in that area. Be careful
    that the privilege level associated with each password is equal to or
    higher that the privilege required for access to the area and its
    associated menu commands.

    Whenever users leave a barricaded message or file area, they lose
    the higher or lower privilege which was conferred on them. As an added
    security measure, if a user logs off or otherwise disconnects while in
    a barricaded area, Opus always resets the last message or file area
    accessed, as appropriate, to area number 1 and resets their privilege
    level to what it was before they entered the barricaded area. YOU
    CANNOT, THEREFORE, BARRICADE FILE AREA NUMBER 1.

    Unlike Opus 1.1x, both message and file areas may be separately
    barricaded by defining a password file associated with the relevant
    area definition in the control file.

    To implement barricaded areas you need to define a generic "warning"
    file shown to callers who attempt to enter the barricaded area. This
    is defined using the USES BARRICADE <filename> control file option
    which you will find in the Session Section of your control file. Here
    is a sample warning file:

        Warning!  Warning!  ^G^G^G

        This is a password protected area. If you have
        stumbled in here by mistake, press ENTER or RETURN to
        return to the system.

        Any other action will be recorded as an attempt to
        enter this area and you will be disconnected.


    In fact, Opus will not disconnect the caller if the caller incorrectly
    guesses the password twice in a row. Instead, Opus will return the
    caller to the area change menu. Your callers do not know that though!

    You also need to define a "password" file which contains the passwords
    and associated privilege level. The file may also contain a caller's
    name and an associated privilege level, in which case the caller will
    not be asked for a password, but will be admitted to the area with the
    assigned privilege (useful for co-sysops maybe). This password file is
    defined with the BARRICADE <filename> option in the area definition
    section of your control file. Each area may have its own password
    file, or you may use the same one in each area. Here is a sample
    password file:



    Page 62                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


        SESAME     ASSTSYSOP ;for area moderator
        SHILOH     PRIVIL    ;for those who can enter echomail messages
        GREYSTOKE  NORMAL    ;for those who cannot enter messages
        PERFECT    NORMAL    ;for those who cannot enter messages
        K9W3F1     SYSOP     ;for the sysop
        Ken Morgan TWIT      ;for poor Ken
        Joe Smith  NORMAL    ;for Joe


    Neither Ken Morgan nor Joe Smith would have to give a password for the
    barricaded area. Instead, their privileges would be automatically set
    by Opus. The comment field after the password is optional, but handy
    to keep track of who has what access.



    3.9 WELCOME FILES

    Opus has a rich assortment of welcome files available for you to
    bend your mind with. Here's a summary:

        * The standard WELCOME file;

        * Custom welcome files (CWFs);

        * Special announcement files (SPANNs);

        * The special OEC file (SPOEC).


    For the particular sequence in which Opus will show these files to a
    caller, refer to the flowchart of the Opus login sequence in section 5
    of the Technical Reference Manual.



    3.9.1 THE STANDARD WELCOME FILE

    The standard welcome file is shown to ALL your callers, if you have
    defined such an file with the USES WELCOME option in the Session
    Section of your control file.

    As this is just a normal OEC file, you can use the Opus Embedded
    Command set in the file to do WAW (wierd and wonderful) things.



     
     
    SETTING UP OPUS V1.70                                        Page 63 
     
     
    3.9.2 SPECIAL ANNOUNCEMENT FILES

    Special announcement files are shown only to those callers whose
    records in the Opus user file you tweak. There are five "counters" in
    each caller record for associated special announcement files. The
    counters can be set to show each of the five special announcement
    files a certain number of times (up to a maximum of 255). Opus will
    then show the caller the corresponding special announcement file and
    decrement the counter by one each time the caller logs on to your
    system.

    To implement this option, you need to define the PATH SPANN option in
    the System Section of your control file to point to the directory in
    which the special announcement files will be stored. The special
    announcement files are named SPANNn.BBS where "n" is a number from 1
    to 5 to correspond with the five counters in each caller's record in
    the user file. The SPANN file is a normal OEC file, so you can use the
    full set of OECs in it. Here's a sample SPANN file:


        >>>> Access Upgraded <<<<

        ^F^F, as you have correctly answered the Q)uestionnaire, your
        access has now been upgraded to VERIFIABLE member.

        Choose O)utside from the M)ain Menu, then M)embership details
        for further information regarding membership.

        TREV.
        (Sysop: Sentry (02) 428-4687 & Sentry's Shadow (02) 418-6682)

        ^A


    No, there is more. You also need to set the relevant SPANN counter(s)
    in the caller's record in the user file. You can either use a program
    called, appropriately enough, SPANN (by Doug Boone) or OUFM (the Opus
    User File Manager by yours truly) to set these counters either
    globally or for specific callers.



    3.9.3 CUSTOM WELCOME FILES

    Custom welcome files (CWFs) are shown to individual callers only. The
    files are shown again and again until you delete them, or you can rig
    up a file which will delete itself using OECs after it has been shown.

    For once, you do not have to specify anything in your control file!
    Instead, there is a special format for the CWF filename: the filename
    is based on the caller's record number in the user file. The records
    in the user file are 1-based (ie, the first record is number 1) to
    make life easy for you. The files have the standard OEC file extension
    (.BBS -- if you use .GBS you better make sure that the caller has the
    required video mode set or the caller will not see your handiwork).


    Page 64                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    The CWFs must be stored in the same directory as the one from which
    you run the Opus program.

    One last point, you do not need to put a ^A pause OEC in these files
    as Opus will add one automatically at the end of the file for you.



    3.9.4 SPECIAL OEC WELCOME FILES

    Special OEC welcome files (SPOECs) are shown only to those callers you
    select. There is a field in the caller's record in the user file for
    defining an 8 letter filename without the extension which is assumed
    to be the standard OEC file .BBS/.GBS extension. You can define this
    file using the OUFM (Opus User File Manager) program. This file
    REPLACES the normal welcome file shown to all callers (ie, the SPOEC
    file is shown instead of the normal welcome file). I have one defined
    in my user record to bypass the normal logon bulletins; although you
    could also skin this hassle by using privilege level OECs in the
    normal welcome file. If your system is used by a club of some sort, a
    SPOEC file may be useful for showing only club members details of
    upcoming events. The only limit is your imagination.



    3.10 THE RELOGGING FUNCTION

    If you, or your callers, need to exit Opus to run a particular online
    program, you can relog on to the system and end up back at the menu
    which you exited from without having to go through the normal log on
    procedure! The infamous Opus relog function <ask Doug>.

    To implement the relog function you need to set the SECURE, RELOG and
    AFTER RELOG EXIT options in the Session Section of your control file.
    Go on, refer to section 2 of the Technical Reference Manual for
    details of these options.

    To exit from Opus you need to set up an _OUTSIDE EXIT menu command
    off one of your menus like this:

        _OUTSIDE      Sysop     "Drop to DOS"  = EXIT 15

    and then trap the DOS errorlevel of 15 in your NERF.BAT batch file
    like so:


        :OPUS
        CHAT 30
        SET PORT=2
        OPUS BBS

        :TEST
        IF ERRORLEVEL 255 GOTO ERROR255
        [...]
        IF ERRORLEVEL 15 GOTO DOS
        IF ERRORLEVEL 4 GOTO ERROR4
        IF ERRORLEVEL 3 GOTO ERROR3
        IF ERRORLEVEL 2 GOTO ERROR2
        IF ERRORLEVEL 1 GOTO OFFLINE
        GOTO ERROR0

        :DOS
        NEWBAUD Q:\OPUS\LASTUS00.DAT
        IF ERRORLEVEL 96 GOTO REMOTE_DROP
        IF ERRORLEVEL 48 GOTO REMOTE_DROP
        IF ERRORLEVEL 24 GOTO REMOTE_DROP
        IF ERRORLEVEL 12 GOTO REMOTE_DROP
        IF ERRORLEVEL 3 GOTO REMOTE_DROP
        IF ERRORLEVEL 0 GOTO LOCAL_DROP

        :REMOTE_DROP
        CTTY COM%PORT%:

        :LOCAL_DROP
        COMMAND

        :RETURN
        Q:
        CD Q:\OPUS
        CTTY CON
        OPUS BBS -O
        GOTO TEST


    and you need to re-run Opus with the -O command line switch.


    IMPORTANT: make sure you define an AFTER RELOG EXIT errorlevel and
    that the flow of your batch file does not keep executing Opus with
    the -O command line switch or else ...

        > Hi everyone, I've been having this strange problem and I
        > can't figure it out.

    ... Opus reload will reload itself over and over again after each
    caller who goes outside.

    The optional Opus caller expiration control system allows the
    termination of caller access based on either expiration date or
    minutes given and used, or both. Since this system operates
    independently of the existing daily time and file download limiting,
    all three forms of limiting can be used in combination. All control
    settings are made on a per caller basis so you can have a mix of
    callers with different forms of limiting. Additional per-user settings
    control whether a caller is disconnected, demoted, both, or neither.



    3.11.1 EXPIRATION CONTROL METHOD

    Expiration control may be based on:

        Date ..... When a caller's ByDate flag is enabled, that caller is
                   "expired" on the given expiry date.

        Time ..... When a caller's ByTime flag is enabled, that caller is
                   "expired" when the caller has used (debited) as many
                   minutes as the caller was given (credited) as shown by
                   the Debit and Credit minutes fields in the caller's
                   user record. These fields act in much the same way as
                   the FidoNet credit/debit fields do in that they
                   continually accumulate and their difference is the
                   actual balance remaining.

    You can set a caller's user record for both Date and Time expiry so as
    to allow the case where you want a user to consume their given minutes
    within some calendar time frame to avoid the case where some low
    activity caller takes 10 years to use the 30 minutes of usage credit.



    3.11.2 HANDLING EXPIRED CALLERS

    The way an expired caller is handled is controlled by the AxeUser and
    DemoteUser flags in the caller's record. If neither is set then the
    caller will only get the relevant warning and/or expiration messages
    (see the section on Implementing Expiration Control below).

        DemoteUser .. If enabled, the caller's privilege is reset to the
                      expiration privilege value in the control file. If
                      that value has not been set, then the caller is
                      forced to the lowest privilege (Twit).

        AxeUser ..... If enabled in the caller's record, the caller is
                      rather unceremoniously disconnected by Opus.

    Both Demote and Axe can be used together so that you can reduced a
    caller's privilege level and stop the caller from logging on. That may
    be handy when you want to signal an external maintenance utility by
    setting the privilege level to something unique for further, external
    processing or purging.



    3.11.3 IMPLEMENTING EXPIRATION CONTROL

    First of all, you need to decide how you are going to implement the
    expiration control system (if at all).

    You can make expiration control automatic for all new callers to your
    system by defining the LOGON XDAYS and/or LOGON XMINS and EXPIRE PRIV
    options in the Session Section of the control file.

    You may also want to define the EXPIRE DAYS, EXPIRE MINUTES and USES
    XDWARN, USES XTWARN, USES XDGONE, USES XTGONE options in the Session
    Section of your control file.

    The USES XD/XTWARN options allow you to define OEC files to give
    callers separate expiration warning messages for date and time expiry
    when callers are within a preset number of days or minutes from
    expiration. These time limits are defined with the EXPIRE DAYS/MINUTES
    options.

    The USES XD/XTGONE options allow you to define OEC files to give
    callers expiration messages for date and time expiry when callers have
    expired.

    When the caller is within the preset number of days from expiration,
    the caller would be shown XDWARN.BBS at logon. Here is a sample file
    using the expiration OECs:

        G'day ^F^F, I just thought you should know that your access to
        this system will expire in ^XD days on ^XC.

        ^A


    If the current date is greater than or equal to the expiry date you
    have set, then the caller is shown XDGONE.BBS which would typically
    say:


        >> Attention <<     Access Expiration    >> Attention <<

        ^F^F, your access to this system expired on ^XC.

        Please bribe the Sysop NOW if you wish further access!

        ^A




    Page 68                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    To implement expiration control fo your existing callers, you will
    need to use OUFM (Opus User File Manager) to set the relevant fields
    in the callers' user records. Refer to the documentation that comes
    with OUFM for further details.



    3.12 "SECTIONS" OR "SIGS"

    Each online user of a system can be allocated a "section" by the
    sysop at logon, or can define their own section from the section menu
    if it has been implemented. The ability to choose sections from the
    section menu can, of course, be restricted by privilege level and/or
    by locks.

    A section restricts a user's access to your Opus system. It is used to
    allocate message and file areas, so that a user will only be able to
    access those areas which are included in their allocated or chosen
    section. You can look at sections as being something like TBBS Sigs,
    except that the use of sections in Opus is optional.

    Callers could use MSG_NAREA and sections to make Opus operate somewhat
    like the old CP/M Citadel BBS system. When you read all the messages
    in one area and then go on to the next area with unread messages, you
    only get those areas that you were interested in.

    Or you can look at sections as being something like TBBS Sigs, except
    that users do not _have_ to use them.



    3.12.1 SYSOP DEFINED SECTIONS

    You define the section(s) to which a message or file area belongs in
    the message or file area definition in the control file (BBS.CTL)
    using the SECTION item. For example, you could setup your system to
    have:

              * an Assembly language section (SECTION AP);
              * a C language section (SECTION CP);
              * a Turbo Pascal section (SECTION TP); and
              * a Programming section (SECTION P).

    If callers are allocated section P by the sysop at logon, or they
    choose that section themselves (if there is a section menu to which
    they have access), then they will only have access to those message
    and file areas which have either the P or A or C section set in their
    area definition (in this example, the Assembly, C and Turbo Pascal
    areas). If callers are allocated section A, or they choose that
    section themselves, they would only have access to message and file
    areas that have the "A" section set in their area definitions (in this
    example, only the Assembly language area).



     
     
    SETTING UP OPUS V1.70                                        Page 69 
     
     
    3.12.2 USER DEFINED SECTIONS

    A User Defined Section (UDS) is a section that callers can create on
    their own. Callers can have any combination of up to 80 areas in their
    section. They can have 1 file area and 79 message areas or 40 message
    areas and 40 file areas, or any other combination. Opus keeps track of
    how many message and how many file areas the caller has selected.

    Although in most ways UDS are just like any other section, User
    Sections have a couple of extensions to be considered, MSG_SCAN,
    F_NEW, MSG_NAREA, F_LOCATE and the NextArea/PriorAreas will no longer
    be concerned with high message/file area limits. They read the area
    table in the user record directly.



    3.12.3 THE SECTION MENU

    A new addition to the Opus V1.70 menu system is the Section Menu. You
    do not have to have a section menu, it is optional. A sample section
    menu is set out below:

        %
        SECTION MENU
        _PICK_SECTION Disgrace "All areas" =
        _PICK_SECTION Disgrace "Programming" = PCA
        _PICK_SECTION Disgrace "LOCAL" = L
        _PICK_SECTION Disgrace "Buy & Sell" = B
        _PICK_SECTION Disgrace "Opus" = O
        _SHOW         Twit     "?Help" = C:\Hlp\Sections
        _MAIN         Twit     "Quit section menu"
        END Menu
        %


    It is worth pointing out that there is no misprint or typographical
    error in the first _PICK_SECTION menu command -- there is nothing
    after the "equals" sign. You NEED this option if you are going to
    allow your callers to get out of their sections. Without it, you will
    only cause yourself and your callers grief ... as several Beta and
    Gamma testers can attest.

    To allow callers to set up their own UDS (User Defined Sections)
    instead of choosing sections which have been set up in advance by the
    sysop, your section menu might look like this:

        %
        SECTION MENU
        _PICK_SECTION Disgrace "All areas" =
        _MAKE_SECTION Disgrace "Make area list"
        _MY_SECTION   Disgrace "Use area list"
        _SHOW         Twit     "?Help" = C:\Hlp\Sections
        _MAIN         Twit     "Quit section menu"
        END Menu
        %


    Page 70                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    The _MAKE_SECTION menu command allows callers to add/delete message
    and/or file areas to their section. The _MY_SECTION menu command then
    allows callers to select their UDS. It is a good idea to include the
    "All areas" option so that callers can quickly and easily reset their
    area list to all areas without having to individually add message and
    file areas.



    3.12.4 RELATED CONTROL FILE OPTIONS

    There are several options in the Session Section of your control
    file that you may need to define:

        USES MAKE c:\help\makesec

    This option defines the help file that will be shown before users
    start making their own user defined section or if they press '?' to
    get help.


        MAKESECTION ABC

    This option defines the section that callers will be dumped into while
    editing their section. Consider that if a user is inside their UDS,
    they could not add any new areas, because no more areas would be
    available to them! You should define this option.


        LOGON SECTION

    This option defines the section which will be assigned to all new
    callers to your system without sysop or caller intervention.


        USES SECTMENU

    This option defines the so-called "ASCII" menu to replace the "normal"
    Opus menu.


        SECTION

    This option is not in the Session Section of your control file. Look
    for it instead in the message and file area definitions. It defines
    the section(s) to which the particular message or file area belongs.


    As ever, full details of these control file option may be found in
    section 2 of the Technical Reference Manual.

    3.12.5 SAFETY FEATURE

    Sections have a special inbuilt safety feature to protect callers
    from themselves and you: if a caller goes into a section and fails to
    get into a file or message area for three tries, Opus will drop the
    caller back to the "default" section that you defined in your control
    file with the MAKESECTION option. You _did_ define that option ...
    better go do it now!



    3.13 TIME ZONE SETTINGS

    Internally, Opus always works in Universal Coordinated Time (what was
    called Greenwich Mean Time when grizzled Opus veterans were not so
    grizzled). You are rarely affected by this. In fact, you may not have
    even realized it until now. Your SCHED.BBS (or whatever name you have
    defined in your control file for the USES SCHEDULE option) file is
    probably in local time ... so you need to tell Opus how to convert
    the time or you will have to learn to live in interesting times.

    Please find the item (below) that applies to you and put it into your
    AUTOEXEC.BAT file.

    4.0 THE OPUS EVENT SYSTEM

    The first thing you need to understand about how events work in Opus
    V1.70 is to understand that the term "event" is convenient, but sort
    of misleading in some cases. What we are talking about are behaviour
    windows that modify the default behaviour that you have set in the
    Opus control file. Events, for some fixed period, change the way Opus
    will work during that period.

    In Opus, you can have an event that runs every day, just weekdays,
    just weekends, one day every week, or every Monday-Wednesday-Friday.
    Events can also run past midnight.

    You can have as many as 254 events in Opus, or as few as 1. There is
    no requirement that you have an external event every day. The event
    manager assumes that there is an event 24 hours away, and looks for
    anything closer. If it does not find anything, Opus will just report
    that the next event is 24 hours away and go on, 24 hours later,
    (assuming there have not been any calls in or out to reset the event
    manager), Opus will just go check the event file again.

    As virtually everyone using Opus 1.03 discovered, Microsoft's time
    library had a glaring weakness when dealing with UTC (Universal
    Coordinated Time, what used to be called GMT). Starting with V1.10,
    Opus does NOT use Microsoft's time library. The environment and the
    DOS clock are read directly.



    4.1 TYPES OF EVENT

    There are seven basic types of event or behaviour window:

    Matrix:         Changes the way Opus handles outgoing and incoming
                    mail (often referred to as Z events).

    User:           Changes the way Opus handles users, giving them more,
                    or less, time and download privileges.

    Scan all:       Forces Opus to scan all echomail message areas for new
                    outgoing echomail messages.

    Housecleaning:  Deletes all those pesky .$$5 files in the outbound
                    mail holding subdirectory.

    External:       Halts Opus operations to return control to DOS or a
                    batch file.


    Page 74                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    Yell:           Opus will allow the remote user to request help from
                    the Sysop if allowed.

    Mailer:         This event can be used to control whether the Opus
                    internal mailer or an external mailer is used.


    Some types of event or behaviour window come in two flavours:

    Forced:         These events MUST start at a certain time, and Opus
                    will get Guido to do whatever it takes to prevent
                    human users from interfering with the start of these
                    events. If for some reason Opus is inactive when a
                    forced event should have started, Opus will execute
                    the event as soon as it starts up again.

    Informal:       These events start and end on a more flexible
                    schedule. They do not interfere with human callers by
                    limiting the caller's time. Instead, they start as
                    soon as Opus is free after the specified start time
                    for the event. Opus will execute any informal events
                    that have not run if it has been inactive for some
                    reason.


    The following list shows which events are which flavour (if any):

    External event: can be forced or informal or neither (see below).

    Matrix window:  always informal, unless they occur in those periods
                    when you do not allow human callers.

    User events:    always informal.

    Scan event:     always informal.

    Yell event:     neither forced nor informal.

    Mailer event:   always forced.

    Housecleaning:  always informal.



    4.2 EXTERNAL EVENTS

    External events are used when you want Opus to stop operating and
    return control to your batch file. You can specify external events as
    being Forced or Informal or you just create an external event without
    declaring it to be either Forced or Informal. In that case the event
    will affect users who log on before the start of the event, but Opus
    will make no effort to execute the event if it was skipped for some
    reason and is now over.

     
     
    THE OPUS EVENT SYSTEM                                        Page 75 
     
     
    There are two inter-relationships between External events and Matrix
    Behaviour Windows (Z events) that should be pointed out:

      *  There is a field called an "errorlevel offset" in the Matrix
         Behaviour Window. This offset will be ADDED to the errorlevel from
         any exit during that behaviour window.

      *  The "Exits suppressed" flag in Matrix Behaviour Windows, does NOT
         affect External Events. It only affects matrix exits such as
         "Exit after Arcmail" and "Exit after Matrix". It is used to
         prevent your system from performing a matrix exit after a mail
         session (eg you may wish to process all incoming mail once only
         after the end of the zone mail hour so that your system is
         available for incoming mail for the whole hour).

    Generally it is better to make all external events last 0 minutes and
    either Forced or Informal so that Opus will release control to the
    batch file for the minimum amount of time necessary to perform the
    specified task or whatever. If you give the event some length, and it
    is completed before that time is up, Opus will exit again with the
    same errorlevel to the batch file over and over until the time period
    specified for the external event has passed.



    4.3 USER EVENTS

    User Events are more accurately described as User Behaviour Windows.
    They allow you a great deal of flexibility in how Opus will treat
    human callers during the time window in which they are enabled.

    There are two active fields in a user behaviour window: the Download
    multiplier and the Time multiplier. These fields only affect callers
    who have a privilege level below ASSISTANT SYSOP. SYSOP and ASSISTANT
    SYSOP are not affected by these behaviour windows.

    A value of "20" is considered to be neutral, users will get exactly
    what you have specified in your Opus control file. A value of "10" in
    the Time Multiplier would give users 1/2 the amount of time specified
    in the PRM file. A value of 50 in the Download Multiplier would give
    users two-and-a-half times as many kilobytes of download access during
    the specified time window.



    Page 76                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    If you have set your Opus control file so that it reports something
    like this:

         DEFINE Normal Cume       120
         DEFINE Normal Time        60
         DEFINE Normal File Limit 500

    and you have a user behaviour window with a Download Multiplier of 30
    and a Time Multiplier of 40, a NORMAL user would get:

         DEFINE Normal Cume 120 * 40/20       =  240
         DEFINE Normal Time 60 * 40/20        =  120
         DEFINE Normal File Limit 500 * 30/20 =  750

    If you had a user event with a Download Multiplier of 0 and a Time
    Multiplier of 10, a NORMAL user would get:

         DEFINE Normal Cume 120 * 10/20      =   60
         DEFINE Normal Time 60 * 10/20       =   30
         DEFINE Normal File Limit 500*  0/20 =    0



    4.4 MAILER EVENTS

    A mailer event lets you decide when you want to use the internal Opus
    mailer or an external mailer as a "front-end" to your Opus system.

    The external mailer command line is specified in the Opus control
    file. Whether you want to use the Opus internal mailer or the external
    mailer as your default mailer may also be set in the Opus control
    file. You can then use the mailer event to override the default
    setting in your Opus control file.

    If an external mailer is chosen, Opus loads and initializes itself,
    and then loads the external mailer. When a call comes in the mailer
    answers the phone. If it is another FidoNet system sending mail, the
    mailer handles everything. If it is a human calling in, the mailer is
    dropped out of memory and Opus takes over. Since Opus is already in
    memory and initialized this method is a LOT faster than the way other
    software deals with external mailers. However, it is memory intensive.



    4.5 MATRIX EVENTS

    Matrix events are more accurately described as Matrix behaviour
    windows. They are primarily used to control the way outbound calls are
    made. Should any calls be made? Should they be local or long distance
    calls? How do you define a "local" call? How often should calls be
    made?

    All matrix behaviour windows are considered to be informal except
    for those in which the behaviour window does not allow human callers.

    4.5.1 MATRIX EVENT FLAGS

    Matrix events have 7 possible flags. You do not have to set any of
    them if you do not wish to use their functionality. The Matrix event
    flags and their meanings are listed below:

    Mail            Allow outbound calls to placed during this window.

    Local-Only      Only make calls that are equal to or below the cost of
                    the local cost field.

    No-Local        Only make calls that are above the value stored in the
                    local cost field.

    Continuous-Mail Only call those systems in the nodelist that are
                    marked as being able to handle continuous incoming
                    mail. (CM in FidoNet.)

    Suppress-Exits  Do not allow matrix exits for packing, unpacking or
                    otherwise processing incoming mail.

    Mail-Only       Do not allow human callers online. Just handle mail.

    Requests        Allow file requests to be honoured. (Usually disabled
                    during the zone mail hour.)

    NO-Out-Reqs     Do NOT allow Opus to make outbound requests. This only
                    works with oMMM V1.70 and OMAIL V0.41 and above by
                    creating special names for the file that forces Opus
                    to make calls. Do NOT send outbound requests during
                    Zone Mail Hour.



    4.5.2 MATRIX EVENT FIELDS

    Matrix events have 5 possible numeric fields. You do not have to set
    any of them if you do not wish to use their functionality. The Matrix
    event fields are set out below:

    Local Cost      Range: 0-255

                    Set the value that will be considered to be a "local"
                    phone call during this event. If you have the Local-
                    Only flag set, then only calls to those boards listed
                    in your NODELIST.DAT file that are at or below the
                    value stored in Local Cost will be made.

                    If you have the No-Local flag set, then only calls to
                    those boards that have costs ABOVE this value will be
                    made.



    Page 78                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    Error Offset    Range: 0-255

                    A value that will be added to any exits made during
                    this event. One use would be to pack mail with
                    different routing verbs at different times of the day.
                    You might want to pack all local mail as HOLD during
                    Zone Mail Hour to keep your board free during ZMH.

    Call-Frequency  Range: 5-40
                    (5 is more frequent, 40 is less frequent)

                    Controls how often Opus will check the outbound mail
                    directory (ie tickle the hard disk unless you are
                    running a disk cache) looking for mail to be sent.
                    Opus will not find something every time, but it will
                    reinitialize the modem each time.

                    The default value is 14. With this setting Opus will
                    place an outbound call roughly every 90 seconds. With
                    a setting of 5, Opus will try to make a call roughly
                    every 10 seconds, with a value of 40, it will be
                    roughly 12 minutes between calls.

    Request limit   Range: 0-255

                    Controls the number of minutes that Opus will allow
                    another system to file request from your system. Opus
                    will check AFTER each requested file is sent to see if
                    the specified number of minutes has expired. If it
                    has, Opus will hang up. Otherwise, Opus will proceed
                    to send the next requested file, even if the time it
                    takes to send that file will exceed the total number
                    of minutes specified in the request limit.


    The word "roughly" came up in that paragraph a lot. The reason is that
    the time between calls has a random factor of +/-25%. So if you have
    the default frequency set, the average time between calls will be 90
    seconds, but it might be as low as 45 seconds or as high as 105
    seconds. With a value of 40, the time between calls might be as low as
    8 minutes and as long as 16 minutes.

    The formula for creating the time to the next outbound call is:

        time = (45 + (rand() % 31)) * call-frequency * call-frequency
               ------------------------------------------------------
                                 14 * 14

    4.6 YELL EVENTS

    Yell events are used to determine when the sysop wishes to allow
    callers to page the sysop for an online chat. If no yell events are
    specified, then users will be told that yell is disabled whenever they
    choose the Y)ell menu command.

    If a yell event exists, and a caller pages the sysop between the
    starting and ending time defined by the yell event, Opus will cause
    the speaker on the sysop's computer to beep. The length of this
    beeping can be controlled by using the "errorlevel" field to set the
    number of seconds for which the speaker is to beep.



    4.7 SCAN ALL EVENTS

    Scan all events cause Opus to scan all echomail message areas, except
    inbound-only areas, for new echomail messages to be scanned out.
    This only works if Opus is handling echomail processing internally.



    4.8 HOUSE-CLEANING EVENTS

    House-cleaning events are used to clean out the .$$n files in the Opus
    outbound mail holding directory (or directories if you are using zoned
    outbound directories. These flag files are incremented from .$$1 to
    .$$5 to prevent Opus from wasting its time and your money making
    unsuccessful calls to systems which CONNECT but do not successfully
    complete a mail transfer for whatever reason. If .$$5 flag files are
    not deleted, Opus would not make calls to those systems again. It is
    therefore a good idea to run a house-cleaning event at least once a
    day, especially if your system is a major mail mover.

    4.9 OVERLAPPING BEHAVIOUR WINDOWS

    The end of a behaviour window is considered to be as important as the
    start of an event, so Opus also tracks the end of an active event. Two
    events of the same kind can overlap. If you have two windows that
    overlap, Event 1 starts at 1:00 and ends at 5:00, Event 2 starts at
    2:00 and ends at 3:00 like this:


                     ÚÄÄ Z event 2 ÄÄ¿
                     ³               ³
            1:00    2:00    3:00    4:00    5:00
             ³       (A)     (B)     (C)     ³
             ³                               ³
             ÀÄÄÄÄÄÄÄÄÄÄ Z event 1 ÄÄÄÄÄÄÄÄÄÄÙ


         A) Next event at 2:00, Event 1 is active.
         B) Next event at 4:00, Event 2 is active.
         C) Next event at 5:00, Event 1 is active.



    4.10  ADVANCED EVENTS FOR TIME TRAVELLERS

    One neat trick that Opus will allow you to use is that events can
    begin and end in different time zones. This can be a lot of help when
    you are trying to handle mail routing through your lowest cost carrier
    and dealing with FidoNet's Zone Mail Hour.

    For example, Sysop-X (Guido?) has a Matrix Event that starts at
    midnight local time (0:00 hours) and ends at 9:00 UTC (the start of
    FidoNet's Zone Mail Hour in Zone 1). The next Matrix Event runs from
    9:00 UTC to 10:00 UTC (Zone Mail Hour in Zone 1) and then another
    event takes over at 10:00 UTC and ends at 6:40 local time.

    Why go through all that?  Simple, when Daylight Savings time ends all
    Sysop-X has to do is reset the time on the computer and the TZ
    environment variable. The events will automatically swing around and
    adjust themselves to either Daylight or Standard time accordingly.

    4.11 HOW TO SET UP EVENTS

    To set up events in Opus V1.70, the program to use is Doug Boone's
    OEVENT.EXE Version 0.81. It was used to generate the event listings in
    section 4.10 above. For further details on the operation of OEVENT,
    please refer to the documentation that comes with OEVENT.

    5.0 WHEN THE SYSOP IS AT THE KEYBOARD

    Opus has four basic modes:

              * When the system is waiting for a call or an event;

              * Sysop "calling" the system from the keyboard;

              * When a caller is on-line; and

              * Chat mode.

    The following sections describe the use of the local keyboard in each
    of these modes.



    5.1 WHEN OPUS IS WAITING FOR A CALL

    When Opus is sitting at the "Ready" prompt waiting for your next lucky
    caller, or the next scheduled event or matrix behaviour window, you
    may:

              * Hold down CONTROL and press C
                Hold down ALT and press Q

                This quits Opus and returns you to DOS.


              * Press ESCape

                This allows you to enter a DOS command. When the DOS
                command completes, you will be returned to Opus. Opus does
                not busy out the phone line during the lifetime of the DOS
                command.


              * Press F1 - F10 function keys

                This runs the batch file associated with the function key
                (see below for setting up these batch files).




    Page 84                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


              * Press Y

                This overrides the scheduled Yell event and forces Yell
                ON;


              * Press U

                This overrides the scheduled Yell event and forces Yell
                OFF;


              * Press T

                This forces Opus to follow the scheduled Yell event;


              * Press the CURSOR UP key

                This increases the delay between outbound mail calls by
                Opus. The bigger the number, the longer the delay is
                between calls, the smaller number, the more often Opus
                will make calls. It is a manual way to override the
                outbound call frequency you set in the event file (see
                Opus Event System section of this manual). With a setting
                of 5 Opus tries to make an outbound call every 10 seconds
                and with a setting of 40, Opus tries to make an outbound
                call every 10 to 15 minutes.


              * Press the CURSOR DOWN key

                This decreases the delay between outbound mail calls by
                Opus. The bigger the number, the longer the delay is
                between calls, the smaller number, the more often Opus
                will make calls. It is a manual way to override the
                outbound call frequency you set in the event file (see
                Opus Event System section of this manual). With a setting
                of 5 Opus tries to make an outbound call every 10 seconds
                and with a setting of 40, Opus tries to make an outbound
                call every 10 to 15 minutes.

              * Press M to select the Matrix Menu

                This option displays the current matrix behaviour window
                setting and gives you the option of checking the status of
                outbound mail (Information), polling another matrix system
                (Poll), unpacking any inbound mail bundles (Unpack), scan
                all your EchoMail message areas (Scan), clear the
                ########.$$n files from your outbound directory or
                directories (Clear undialables) or return to Opus (Quit).
                While you are in the Matrix Menu, Opus will busy out the
                phone line using the method specified in the control file
                (refer to the BUSY option in section 2 of the Technical
                Reference Manual).


              * Press C

                This forces Opus to make an outbound call now provided
                you have some outbound mail to deliver, the current matrix
                behaviour window and local call cost settings allow
                outbound calls at this time etc. You may have to press C
                several times to attract the attention of Opus. This is
                normal behaviour.


              * Press K

                This lets you log on to your system in "keyboard mode".
                (This is sometimes called "testmode" by a certain LCD.)
                See further the keyboard mode section below.



    5.1.1 SETTING UP F1-F10 BATCH FILES

    To run a batch file associated with one of the function keys F1
    through F10, batch files with the names F1.BAT through F10.BAT must
    exist in the Opus miscellaneous directory (ie the directory defined in
    your control file with the PATH MISC option).

    F1 usually means help, right?  (I hope you pass this impromptu test or
    Guido will ...) Right. My F1.BAT file contains the following, which is
    very useful for those of us whose memories are in recess:

    the other function key batch files is set ut below with comments (do
    not enter the comments if you decide to use it!):


    @echo off                       ;avoid screen clutter DOS 3.3+
    at com%PORT%: h1                ;busy out the phone line
    <program name> <parameters>     ;insert your program etc here
    at com%PORT%: h0                ;hangup the modem
    goto end                        ;just to be safe
    :END                            ; "   "  "   "
    c:                              ; "   "  "   "
    cd \opus                        ; "   "  "   "


    * AT is a small program which sends AT commands to your modem; if you
      do not have this program (stocked by most BBS file areas) you may be
      able to use:  ECHO ATH1 > COM1:  and  ECHO ATH0 > COM1:

    * %PORT% is a DOS environment variable containing the communications
      port which is used by Opus on the system invoking the batch file
      (very handy if you are running a multi-line system). You can set it
      by placing SET PORT=1 (for com1:) in your NERF.BAT batch file;
      alternatively you can simply hardcode the entry in the function
      batch file like so:  AT COM1: H0  and  AT COM1: H1

    * <program name> inserting COMMAND here will let you drop to DOS and
      busy out the phone line.

    5.2 SYSOP CALLING FROM KEYBOARD

    When Opus is sitting at the "Ready" prompt waiting for a call or the
    next scheduled event, the sysop can log on to the system by pressing
    K. Opus will ask you to confirm it is you, will ask for your password
    etc and then log you on to the system.

    The keyboard works just like it would if you were calling in using a
    modem. There is only one primary difference. When Opus asks for your
    name, you can quickly get back to DOS by just pressing ENTER. You can
    also terminate Opus <ouch> and get back to DOS by typing ALT-X from
    anywhere inside Opus (this also works remotely, Opus will log you off
    without asking you any questions at all, if you are using Avatar
    emulation to transfer ALT keys over the modem line -- see further
    below).

    A few things are different. If you find that Opus is not listening to
    your every keystroke when you try to abort searches and listings, and
    you have VIDEO IBM set in the Equipment Section of the control file,
    change it to VIDEO DOS and Opus may just pay more attention to your
    pounding on the keyboard. Also note that if you have IBM VIDEO set,
    any Avatar or ANSI graphics commands will be written straight to the
    screen ... not a very pretty sight unless you have honed your skill to
    translate these commands on the fly.

    In keyboard mode OpEd, the Opus full-screen editor, accepts additional
    keyboard commands as follows:

              ALT-R  Open a quotation window
              ALT-Q  Copy four lines of quotation into reply
              ALT-X  Abort message
              ALT-W  Save message

              +      Copy four lines of quotation into reply

              TAB    (Insert 8 spaces (insert mode)
                     (Overwrite 8 characters (overwrite mode)

              PgUp   Scroll message up
              PgDn   Scroll message down
              CUP    Cursor up
              CUD    Cursor down
              CUL    Cursor left
              CUR    Cursor right

              HOME   Move cursor to beginning of line
              END    Move cursor to end of line

              INS    Turn insert mode on
              DEL    Delete character under cursor

              F1     Help screen
              F10    Editor Menu

    If you call your system remotely and have Avatar emulation turned on,

    and are using a proper Avatar terminal emulator (such as TinyTerm or
    FrontDoor), you can transfer those keys over the phone line and use
    them in OpEd (to use OpEd you need at least an 80x25 screen AND screen
    clear turned on). To allow this transfer, press ScrollLock in
    FrontDoor, or Shift-F1 in TinyTerm, which will tell these programs to
    transfer any function keys remotely. The same key that turns this
    feature on in these two terminal programs turns it off.



    5.3 WHEN A CALLER IS ONLINE

    When a caller is online, there are two different keyboard modes
    available: (1) the sysop can type commands as if the caller had typed
    them, and (2) the sysop can obtain information about the caller and
    change some of it while the caller is still online -- Opus will
    remember any changes made for next time the caller logs on.

    The full list of keyboard commands available while a caller is online
    are set out below:


              <up arrow>          Add 1 minute to the caller's time

              <down arrow>        Subtract 1 minute from the caller's
                                  time.

              C                   Go into chat mode (see below).

              CONTROL-X           Ignominiously hang up on the caller!

              A (or CONTROL-A)    Turn on the local keyboard. Opus will
                                  take commands from your keyboard or from
                                  the modem, but your keyboard had
                                  priority.

              <ESC>               Turn off the local keyboard.

              - ("minus")         Lower the privilege level of the caller
                                  by one notch. Starting with Opus V1.70,
                                  this also changes the caller's time and
                                  download allowances to reflect those
                                  associated with the new privilege level
                                  for this call.

              + ("plus")          Raise the caller's privilege level by
                                  one notch. Starting with Opus V1.70,
                                  this also changes the caller's time and
                                  download allowances to reflect those
                                  associated with the new privilege level
                                  for this call.

              O (or CONTROL-O)    Turn off SNOOP. Only status-type
                                  messages appear on your monitor when the
                                  SNOOP is turned off.

              N (or CONTROL-N)    Turn on SNOOP mode. Your monitor will
                                  show everything that the caller's
                                  monitor shows.

              Z                   Zero the cumulative daily time for the
                                  caller. This has NO EFFECT on the time
                                  for the current call ... only the total
                                  time spent online for the day. Use <up>
                                  and <down> to change the caller's time
                                  limit for the call that is in progress.

              ?                   Show a detailed chart of information
                                  about the caller (eg keys, user macros,
                                  number of calls, time online today, file
                                  up/down loads etc, whether chat was
                                  requested).

              K                   Display the caller's keys. You can then
                                  toggle keys on or off by pressing those
                                  keys that you want to toggle on or off.
                                  This will cause the keys to redisplay.
                                  The caller's current keys are shown in
                                  upper case, the other keys are shown in
                                  lower case. Press ENTER to finish
                                  toggling the keys.

             The NIEL KEYS are sometimes called "function keys" by those
             who do not live in Dallas. Ask any grizzled Dallas Opus
             veteran why! The Niel Keys are a set of keys that work like
             photon torpedoes. You can send any one of ten OEC (BBS/GBS)
             files to the caller at the press of a button ... which means
             they can have ANSI graphics and OECs to do everything from
             greet the caller with the caller's own name, send a quote of
             the day, or even hang up on the caller (or all of the above).
             The F1.BBS / F1.GBS) files must be located in the Opus
             miscellaneous directory which is defined in the control file
             with the PATH MISC option.

             <unknown key>        If you press any other key ... you will
                                  be shown a short status screen and a
                                  brief menu of some of these commands.


    5.4 CHAT MODE

    Starting with Opus V1.10, chat mode is only available if you have
    loaded George Stanislav's "chat fossil" (a small Terminate and Stay
    Resident program) or you are using one of the several external chat
    programs which are available (eg William Beebe's OPHONE) via an
    external menu command.

    The chat fossil should be loaded from the NERF.BAT batch file which
    you use to start Opus. Load it just after the point that you load your
    fossil. If you run DESQview and load your fossil outside of DESQview,
    then load the chat module outside also.

    To chat with a caller is who online, simply press C. To end chat mode,
    use ALT-Q.



    5.4.1 CONFIGURING THE CHAT FOSSIL

    You can configure CHAT.COM to slow down between the individual beeps.
    CHAT uses a very simple method of waiting between the beeps: it loops
    so many times. The default it uses is a 4.77 MHz PC. On any faster
    computer this is not the way to go! To slow it down, simply place a
    number on the command line.

              EXAMPLE, on a 386SX-16 computer:  chat 30

    This tells CHAT to repeat the loop 30 times. Play with the value till
    you find one that suits your particular system.

    6.0 THE MATRIX

    This is a general explanation of the procedures involved in setting up
    your system to send messages from your system to other systems in the
    Matrix. It assumes that you have followed the procedures outlined in
    the section in this manual entitled "Setting Up Opus V1.70" -- if you
    have not followed those procedures exactly, this section may not be of
    much help to you.

    Skip this section if you do not want to run netmail ... there is no
    rule that says you have to run netmail.

    Uhuh, I thought you might ... read on then.



    6.1 NETMAIL FOR THE COMPLETE NOVICE

    This section is dedicated to the sysop who has no previous experience
    with netmail. If you follow the step-by-step instructions, you will
    quickly set up simple node-to-node netmail. This does not cover
    netmail comprehensively, but it will get you up and running without a
    lot of frustration. Advanced netmail topics will be covered in other
    sections of the manual. EchoMail is also dealt with in its own section
    of this manual.

    The novice's introduction to the Matrix can be overwhelming,
    especially with all the jargon and programs that abound:

    documentation or information covers it all.



    6.2 FILES REQUIRED FOR NETMAIL

    If you check out an active Opus-CBCS, you will undoubtedly see many
    programs for doing all kinds of wonderful and interesting things.
    However, we are trying to save time and get you going. So here is a
    list of only the essentials that you will need:


    oMMM  originally by Wynn Wagner III

    oMMM stands for the Opus Matrix Message Masher. This program is used
    to bundle messages for sending to other systems in the Matrix. You
    can use other similar programs which bundle messages, but oMMM was
    specifically written to support Opus and has some Opus-specific
    widgets that may not be found in other similar programs.


    NODELIST

    This is your "phone directory" of other systems in the Matrix. It
    contains information about each system's name, location, sysop,
    maximum baud rate and special information on operating times and types
    of mail that can be processed.

    The nodelist will be in a file named something like NODELIST.107 (the
    107 means it was published on the 107th day of the year). The file is
    usually found compressed inside an archive that will have a file
    extension something like .A07 (ie the first digit of the raw
    nodelist's filename extension becomes an A to indicate that file is
    ARChived); such a file will need to be uncompressed before it can be
    used.

     
     
    THE MATRIX                                                   Page 93 
     
     
    The nodelist is published weekly by the FidoNet International
    Coordinator and available from most FidoNet bulletin board systems.
    Ask your local, friendly, FidoNet sysop if you cannot find it. In
    fact, it may pay to make friends with a local sysop because the file
    is currently over half-a-megabyte in size when archived, and just
    under one megabyte when unarchived. Downloading the nodelist at 2400
    bps is not exactly high on the fun scale.


    OPARSE    by Doug Boone
    =or=
    PARSELST  by Bob Hartman

    This program is used to "compile" or "translate" the raw NODELIST data
    into a form usable by Opus. For example, the program will strip the
    area codes from local phone numbers. The program can also process a
    per-message "cost" item. This is the amount you would charge your
    users for sending a message, should you decide to give them access to
    the Matrix message area. Opus will use the "cost" information to
    decide whether a call to a remote system is local or long-distance.

    OPARSE will generate the advanced Opus V1.70 Version 7 nodelist files;
    PARSELST will generate the "old" Version 6 nodelist files used by Opus
    1.1x and some other mailer programs.


    ARCA.COM  by Vernon D. Buerg

    Used to create compressed mail bundles.  DO NOT SUBSTITUTE ANY FILE
    COMPRESSION PROGRAM THAT CREATES COMPRESSED FILES DIFFERENTLY FROM
    ARCA without the prior approval of all of the other systems to which
    you intend sending mail bundles. ARCA is the lowest common denominator
    in file compression which is supported by every Matrix system. Other
    file compressors may not be supported by Matrix systems.

    Used to uncompress mail bundles from other systems which have been
    compressed with ARCA or another compatible file compressor.

    6.3 AN OVERVIEW OF NETMAIL

    Most novices are quickly confused by the complexities of netmail, but
    would appreciate a simple overview. The following flowcharts show what
    happens to incoming and outgoing mail bundles and which programs
    operate on them. Note that once your nodelist is compiled, only four
    programs are required to handle all forms of node-to-node mail: OPUS,
    ARCA, ARCE, and oMMM.

    6.4 QUICK START TO NETMAIL

    This section will list each step required to get node-to-node netmail
    working. It is a "cookbook". Rather than attempt to explain it all
    here, some assumptions are going to be made to keep it simple. You may
    wish to change things later. To get your system up and running
    quickly, the following assumptions have been made:

    * your system has at least 256k memory available to run Opus; and

    * your Opus system directory is C:\OPUS. If it is not, you will need
      to substitute your own directory pathname in the following
      instructions.


    Page 96                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    (1)  Place the following programs and files in your Opus system
         directory (usually C:\OPUS where OPUS.EXE resides):

         OPUS.EXE                   ARCA.COM
         BBS.CTL                    ARCE.COM
         oMMM.EXE                   NACL.EXE
         oMMM.CFG                   NACL.HLP
         OEVENT.EXE                 NACL.MSG

         OPARSE.EXE      =or=       PARSELST.EXE

         The Latest NODELIST.??? file


    (2)  Edit the PARSELST or OPARSE control file (PARSELST.CFG or
         OPARSE.LST) to represent your phone costs and local area code
         (see the documentation included with the PARSELST or OPARSE
         program).

         In the PARSELST.CFG file make sure you set the following options
         for Opus V1.70:

                                 ; Stuff everyone should have:
         Node 3:711/401          ; Your network address
         Country 61              ; Your country phone code
         MaxBaud 9600            ; Your highest baud rate

                                 ; For Opus V1.70 use the following:
         Complete                ; Generate entire nodelist
         UseZone                 ; Do not change Zone to Region
         Version6                ; Generate Version 6 format files


    (3)  Compile the nodelist by running OPARSE or PARSELST.


    (4)  Create the following directories:

         C:\MSG\NET\         (where the individual messages are stored)
         C:\FILE\NET\        (where inbound files are stored)
         C:\OPUS\OUTBOUND\   (where outgoing message bundles are stored)

         NOTE: if you are going to be sending netmail directly to
         different Zones (ie, not routing it via the zonegate systems),
         you need to also create a C:\OPUS\OUTBOUND.ZZZ directory for each
         Zone to which you will be sending mail. The .ZZZ is the
         HEXADECIMAL number of the Zone, so Zone 3 is 3, but Zone 16 is
         10.

         IMPORTANT: If you do create additional "zoned" outbound
         directories, make sure that they appear in your directory IN
         ORDER or else you will experience some grief to put it mildly
         (just ask Paul "I've broken it, Doug" Kelly). Watch out for disk
         defragmenters which order directory entries alphabetically!

    (5)  There are several options in your Opus Control File which must be
         set in order to handle netmail. These options appear in two
         sections of the control file, "Equipment Section" and "Matrix and
         EchoMail Section". Since this section is devoted to the novice,
         all non-essential advanced options will be skipped. For full
         details of these control file options, refer to section 2 of the
         Opus Technical Reference Manual. Edit your Opus control file
         (named BBS.CTL) as follows:

         The Equipment Section

         OUTPUT COM1:       % If your modem is attached to COM2:
                            % substitute that for COM1: here.

         BAUD MAXIMUM 2400  % If your modem goes faster, substitute its
                            % top speed here (typically 19200 or 38400 for
                            % high speed modems).

         INIT ATZ|          % The character string for Opus to send to
                            % your modem to initialise it.
                            % You should place any commands required to
                            % setup your modem in the batch file which
                            % runs Opus and store them in your modem's
                            % non-volatile memory using the AT&W command.
                            % If your modem does not have non-volatile
                            % memory (ie it does not remember settings
                            % when you turn the power off) you will need
                            % to put your full initialisation string here.

         DIAL PREFIX ATDT   % The character string for Opus to send to
                            % your modem before the phone number to cause
                            % it to dial out.
                            % If your phone only supports pulse dialing
                            % substitute ATDP for ATDT.
                            % This is where you could add any special
                            % characters required for ALL outbound phone
                            % calls. For example, "ATDT0,," to go through
                            % a PABX and obtain an outside line.

         DIAL SUFFIX |      % The character for Opus to send after the
                            % phone number. Usually just a carriage
                            % return, represented by the "|" character.

         MASK CARRIER 128   % Refer to the Opus Technical Reference Manual
                            % if you must know what this means.

         MASK HANDHSHAKING CTS   % May be required for high speed modems or
                                 % modems that can accept data faster than
                                 % they send it PROVIDED you have setup
                                 % your modem to use "hardware flow
                                 % control".

         Create a matrix message area definition in the Opus control file.
         It should reference the directory C:\MSG\NET\ and the message
         type should be "Matrix". Here is a sample Matrix message area
         definition with just the bare essentials:

         AREA   0005   MATRIX          % Area number and name
         MATRIX                        % Matrix type message area
         ACCESS PRIV   Disgrace        % Access for access to the area
         EDIT PRIV     Sysop           % Access for E)nter & R)eply
         PATH C:\MSG\NET\              % Path to your matrix message area
         TITLE Netmail                 % Title for this message area
         END AREA                      % End of message area definition


    (6)  Use NACL to compile your now modified BBS.CTL control file. NACL
         will produce a file called BBS.PRM which is the compiled version
         of the Opus control file. To compile your control file type the
         following line and press ENTER:

         NACL /L /V /I BBS > REPORT

         If there are any problems with the compilation of your BBS.CTL
         file, error messages listing the line numbers of the problem
         lines may be found in the file REPORT which is created using the
         above NACL command line. Use the error messages to track down the
         problem(s) and fix them; then recompile.


    (7)  Make sure you have loaded your FOSSIL program by running the
         program (eg OPUSCOM1.COM, OPUSCOMM.COM or X00.COM) =or=  by
         installing your FOSSIL device driver by putting a "device=" line
         in your CONFIG.SYS file in the root directory (c:\) of your boot
         drive and rebooting (eg DEVICE=C:\X00.SYS).


    (8)  Run Opus by typing OPUS BBS and pressing ENTER.

    (9)  If you created the default event schedule with OEVENT.EXE, Opus
         outbound netmail behaviour should default to the settings in your
         control file. To confirm this is true, go to the Matrix menu
         (press "M" at the ready prompt while Opus is waiting for a
         call). Select the I)nformation option. At the top of the screen
         it should say:  "Matrix Behavior: LOCAL"


    (10) Test the integrity of your setup by selecting the M)atrix menu
         (press M while Opus is sitting at the ready prompt) and then
         choose the P)oll option from the menu to call a known node in
         your local area. This part is really satisfying if everything
         works correctly. If it does not work, pay attention to any error
         messages which might hint at the problem, and then recheck
         EVERYTHING.


    (11) Terminate Opus by pressing ALT-Q. Now edit the oMMM configuration
         file to reflect your system (refer to the documentation included
         with oMMM for further details of the options in this file). The
         following is an example of a very simple, working oMMM.CFG file:

         =============================================================
          ; this is line one of the file oMMM.CFG
          ; path to your matrix message area
          MESSAGEPATH     c:\msg\net

          ; path to your outbound message holding area
          ; only specify your primary outbound path
          HOLDPATH        c:\opus\outbound

          ; Matrix address of system.
          ADDRESS    65535:65535/65535.0  ;equivalent to -1:-1/-1.0

          ; Define the program for creating compressed mail packets.
          Define_Stuffer  ARC  arca

          ; this is the last line of the file oMMM.CFG
         ============================================================

         Run oMMM (type oMMM and press ENTER) and see if it terminates
         with any error messages. If it does, it will usually tell you the
         line number of the line in the oMMM.CFG file where the problem
         occurred so that you can correct it. You can ignore its complaint
         that there is no route file; you do not need one for the moment
         (refer to the oMMM documentation for details of the route file if
         you are curious).

    (12) Log on from the keyboard (type K at the ready prompt while Opus
         is waiting for a call). Enter a message in your Matrix mail area
         to a sysop of a local node, preferably one running Opus that can
         accept mail at any time. Mark the message as "Crash" (Answer YES
         to the CRASH question). After logging off, terminate Opus with
         ALT-Q and then run oMMM. oMMM will move any messages you have
         created in your matrix message area to the outbound holding area.
         Look for a screen report that it is processing the message.


    (13) Re-run Opus (OPUS BBS). Select the M)atrix menu (press "M" when
         Opus is at the ready prompt waiting for a call) and choose
         I)nformation; it should show your message in the outbound area,
         waiting to be sent. After Q)uitting the M)atrix menu, Opus will
         wait a few minutes, then attempt to send the message. If you are
         anxious, you can select the C)all option from the keyboard. You
         may have to press C several times to get Opus to pay attention.
         This will make Opus peek in the outbound holding area and send
         the mail immediately, regardless of cost. You can try it again
         with a file attached. Just attach a file when entering a message
         in the Matrix message area.


    (14) Test your ability to receive and unpack mail by having a local
         sysop send mail and files to you. If everything is working
         correctly, you will see it come in. If Opus does not unpack it
         automatically, choose the M)atrix menu, select U)npack and the
         mail bundle will be unpacked and the message(s) placed in the
         Matrix message area for you. Log on from the keyboard and verify
         the message(s) made it there.


    (15) Create a batch file, NERF.BAT, to run Opus and automate the
         bundling of mail by oMMM. The following is a very bare bones
         example NERF.BAT batch file which will handle mail bundling
         automagically (the file consists of the lines between the two
         lines of "======", with each line starting in column 1):

         ==================================
         C:
         CD \OPUS
         :OPUS
         OPUS BBS
         :TEST
         IF ERRORLEVEL 16 GOTO BUNDLE
         IF ERRORLEVEL 1 GOTO OFFLINE
         :BUNDLE
         oMMM
         GOTO OPUS
         :OFFLINE

         ==================================

    6.5 OPUS DEFAULT NETMAIL BEHAVIOUR

    Opus can be configured in many different ways to accommodate the many
    variables in netmail as well as your own preferences. Some of the
    variables in netmail are:

         * your own system configuration - see the BBS.CTL file and refer
           to section 2 of the Opus Technical Reference Manual;

         * cost of outgoing phone calls - refer to the documentation for
           your nodelist compiler program for setting call costs, and to
           the section 4 of this manual on the Opus Event System for
           setting the cost of what are to be regarded as "local" calls;

         * scheduling mail traffic to conform to local, national or
           international mail schedules (eg Zone mail hours) - refer to
           section of 4 this manual describing the Opus event system and
           to the oMMM documentation which describes routing;

         * the display of various attributes associated with a netmail
           message while reading messages in Opus - refer to the BBS.CTL
           file and to section 2 of the Opus Technical Reference Manual;

         * the ability to define various attributes of a netmail message.



    6.5.1 BEHAVIOUR WINDOWS

    Doing outbound mail with Opus is fairly simple. In fact, getting that
    message across has been one of the toughest jobs.

    Idea #1: With Opus, "mail events" do not exist. Instead, there are
             matrix "behaviour windows."

    With an event, you have to give every detail ... making statements
    that are procedural in nature. With a behaviour window, you paint with
    a wide brush telling the system what to do with different classes of
    remote system.

    When systems could handle Matrix mail only during special times,
    routing and times were important. Now that most systems can process
    mail at any time, the idea of a schedule becomes less important.

    The item of prime importance in Opus is COST. We are going to try to
    relieve you of the tedious details of scheduling and concentrate on
    doing things for the least cost. More on this later.



     
     
    THE MATRIX                                                   Page 103 
     
     
    6.5.2 BUILDING MAIL BUNDLES

    Idea #2: A "bundle" is what some other systems call a "packet." In
             network operations, a packet has a special meaning ... a
             meaning that has nothing to do with network mail. An "XModem
             Block" is a packet in network terminology. To avoid confusion
             with an established word, Opus documentation use "bundle".

    With some programs, bundles are built every time a mail schedule
    starts. As a result, one message may be put into a bundle several
    times. With Opus, bundles are built once. As Opus has no internal
    bundler (the thing that maintains message bundles destined for some
    other system) you must use an external program called oMMM (Opus
    Matrix Message Masher). You can exit Opus with a preset DOS errorlevel
    to call the bundler program when the contents of the Matrix area
    changes (refer to the AFTER EDIT EXIT <number> line in the Opus
    control file).



    6.5.3 FILENAMES DRIVE OUTBOUND MAIL

    Idea #3: The driving force behind outbound message and file traffic is
             filenames!

    You will have special subdirectories set aside just for bundles and
    other Matrix files. These subdirectories belong to Opus and should not
    have anything else put in there. Opus will maintain these
    subdirectories for you.

    As soon as you run oMMM, messages that are marked KILL/SENT in your
    Matrix message area will disappear. They have not been sent, yet. They
    have just been bundled up and deposited in your outbound mail holding
    area, ready to go.


    Bundle filenames

    The filenames of the bundles tell Opus how to treat the different
    bundles. Here is a typical bundle name:

              12345678.OUT

    That says the bundle is for 1234/5678.  The numbers are in hexadecimal
    (base 16). The ".OUT" means it is a regular bundle and, if left with
    that extension, will be treated by Opus like a .DUT file (see below).

    Other bundle extensions include:


              .CUT ... send the bundle to the destination node NOW,
                       regardless of cost;



    Page 104                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


              .DUT ... send the mail direct to the other node without
                       routing it via another system; if the destination
                       node can accept CM (Continuous Mail, ie, mail at
                       any time) send it now provided there is no Opus
                       behaviour window overriding this directive (eg
                       local call cost is observed - see further the
                       section 4 of this manual on the Opus Event System);

              .HUT ... hold the bundle for pickup by the destination node;

              .CRT ... the same as CUT but with an attached file request;

              .DRT ... the same as DUT but with an attached file request;

              .HRT ... the same as HUT but with an attached file request;

              .ORT ... the same as OUT but with an attached file request.

    One nice thing is that you can manually change the filename's
    extension if you need to do so. That would change the behaviour of the
    bundle the next time Opus sees it. Only change it if you know what you
    are doing!

    The oMMM program knows about these extensions and creates them based
    on information you put into the oMMM route file.  You will have
    statements like this:

              ONEHOLD 1:119/5

    That would create a .HUT bundle file of messages addressed to 1:119/5
    that are to be HELD for 1:119/5 to pickup when it calls.


    Flow file names

    Files are also sent through the Matrix. oMMM builds and maintains a
    file that tells Opus what files to send to destination systems and
    what files to hold for pickup by destination systems. A typical "file
    attach" file might be named:

              12345678.FLO

    Other flow file extensions are:

              .HLO ... hold these files for pickup

              .CLO ... crash these files to the other system NOW,
                       regardless of the cost!

              .DLO ... send these files if the destination is capable of
                       receiving CM (Continuous Mail, ie, can accept mail
                       at any time).

     
     
    THE MATRIX                                                   Page 105 
     
     
    A flow file is just a text file. It contains a list of files that are
    to be sent to another system, for example:

              #c:\opus\outbound\00096581.mo1
              #e:\pascal\program.arc

    Now for a few details about what may be contained in flow files:

              * Filenames in a flow file never include wildcard characters
                such as *.* or ????????.ARC etc;

              * Filenames in a flow file should always be fully pathed
                with disk drive letter and full directory path from the
                root directory (eg c:\opus\outbound\00095681.mo1 and not
                just 00095681.mo1);

              * If the first character in front of the disk drive letter
                is a # (hash sign or American pound sign -- NOT an English
                pound sign!) , Opus will truncate the file (make it zero
                bytes in length) after it has been successfully sent to,
                or picked up by, the destination system;

              * If the first character in front of the disk drive letter
                is a ^, Opus will delete the file after it has been
                successfully sent to, or picked up by, the destination
                system;

              * If there is no character in front of the drive letter, the
                file will not be touched after it has been successfully
                sent to, or picked up by, the destination system.


    Compressed messages

    The oMMM program will compress messages for you using your favourite
    file compressor. Do not forget that the only method of compression
    that is supported by ALL nodes in FidoNet is the original ARC
    compression employed by ARCA (to create compressed files) and ARCE
    (to extract compressed files). Details on how this is done may be
    found in the documentation which comes with oMMM.

    oMMM creates archives using the same numbering convention as other
    message archive programs. The filename is the difference between the
    sender's net/node and the receiver's net/node. The file extension is
    ."MO#" where `#' is a number between 0 and 9. In this case, MO stands
    for "Monday". oMMM will also produce "TU", "WE", "TH", "FR", "SA" and
    "SU" files depending on the day of the week when the archive is
    created.


    6.6 HOW IT ALL WORKS

    So far, we have covered bundles and flow files. We have also hit on
    some of the high points of oMMM. More detailed information on oMMM may
    be found in the documentation which comes with oMMM.


    Page 106                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    This is the flow of a message ...

    If I have written a message to Doug Boone, the message is in my Matrix
    message area and I have flagged it as KILL/SENT and CRASH (ie, I do
    not want to keep a copy, so th original in the Matrix message area
    directory will be deleted after it has been bundled and moved by oMMM
    to my outbound mail holding directory). See below for why I used
    CRASH.

    oMMM is run, and converts the message into a bundle in the outbound
    holding directory. In my route control file for oMMM, I have this:

              ONECM 1:119/5 1:119/All

    This route control file line tells oMMM to build a compressed message
    bundle using my favourite file compressor (whatever is specified in
    the oMMM.CFG file) to 1:119/5 and mark it CRASH. In the bundle will be
    any messages to Doug (119/5) as well as messages to anybody else in
    Net 119. The ONECM verb should only be used when you know the
    destination system can receive continuous mail (the nodelist entry for
    the destination node is marked CM) and you want to send the message
    NOW, regardless of the cost.

    Now there is one GOTCHA that must be mentioned. If you are in a
    different zone from the zone you are sending to, AND you wish to send
    the message DIRECT from your system to the system in the other zone,
    you MUST mark the message as CRASH in the message editor or the
    message will be routed via the appropriate Zonegate system instead of
    being sent direct.

    If I did not want to incur the expense of an international phone call
    to send mail to Doug, in my oMMM ROUTE.CTL I could use the following
    lines instead:

              UNCM 1:119/5
              ONEHOLD 1:119/5

    First oMMM bundles messages it finds in the Matrix message area, then
    oMMM processes lines in the route control file sequentially -- one
    after the other starting with the first line. In this example, oMMM
    would create a compressed mail bundle containing any messages to
    1:119/5 and mark it as a CRASH bundle (using the .CLO extension for
    the flow file). The UNCM verb would then turn the flow file into a
    normal .FLO flow file, and the ONEHOLD verb would change that .FLO
    flow file into a .HLO flow file. The mail will now be held for 1:119/5
    to collect when Doug calls me.

    Enter Opus, stage right.

    Opus can tell by looking at the outbound holding subdirectory that
    there is a bundle for Doug. Opus infers from the .CLO extension that
    Doug's system can receive continuous mail.

    It is in the middle of the afternoon. Phone rates between Sydney,
    Australia and Chico, California are the highest that they will be all
    day. It is a bad time to call.

    We are not controlling calling times because of our software. The
    software does not care. Both ends can handle Matrix traffic anytime.
    We are controlling calling times based on the phone rates.

    I have a Matrix behaviour window (Z-event) set in Opus that tells the
    system to make daytime calls only to local systems that can receive
    continuous mail.



    6.7 CONTROLLING OUTBOUND CALLS

    You have two primary methods for controlling phone calls made by your
    Opus system: the Opus control file (BBS.CTL) and the event manager
    program which manages the schedule file of events.

    The control file method is in effect if there is no other event to
    override it. Matrix behaviour windows or Z-Events described below
    are used to override these control file events.



    6.7.1 OPUS CONTROL FILE

    To disable outbound calls, uncomment this line (remove the  percent
    sign % from in front of the line) in your Opus control file:

              SEND NOTHING

    To disable long distance outbound calls, uncomment this line in your
    Opus control file:

              SEND LOCAL



    Page 108                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    To enable the sending of mail to nodes which can accept Continuous
    Mail (these nodes are marked with the CM flag in the nodelist), ie,
    can accept mail 24 hours a day, uncomment this line in your Opus
    control file:

              SEND CM

    With those restrictions, Opus now attempts to send any outbound
    mail it finds in the outbound mail holding area(s).

    If you want to keep humans off-line during a critical mail period,
    uncomment this line in the Opus control file:

              REFUSE HUMAN CALLERS

    There is a way to override these control file settings: Matrix
    behaviour windows (or Z-Events). Read on ...



    6.7.2 MATRIX BEHAVIOUR WINDOWS

    A Matrix behaviour window or Z-Event is set up using the Opus Event
    Manager, OEVENT.EXE by Doug Boone. The event starts out looking like
    any other event ... except that it has a Z for the tag.

                        +----------------------------------------------+
                        |                                              |
                        | "But what HAPPENS during this event?"        |
                        |                                              |
                        | "Nothing.  It's not a real event.  A better  |
                        |  phrase would be BEHAVIOUR WINDOW."          |
                        |                                              |
                        |                              Anonymous       |
                        +----------------------------------------------+

    When a Matrix behaviour window or Z-Event is in progress, its settings
    remain in effect until the next "Z" event.  In other words, the
    settings do NOT RETURN TO THEIR ORIGINAL VALUE at the "end" of this
    event.

    If you declare a Matrix behaviour window or Z-Event for every day of
    the week from 09:00 (9am) to 12:00 (noon), the behaviour you describe
    in that behaviour window will be in effect for those three hours.
    Here is the part that needs to be stressed: at noon, the behaviour
    will remain in effect unless there is another behaviour window
    declared to take effect then.

     
     
    THE MATRIX                                                   Page 109 
     
     
    That should probably be repeated:

            * You can set up Matrix behaviour in the Opus control file
              (BBS.CTL). If Opus runs into a Matrix behaviour window or
              Z-Event that is in progress, those control file values are
              gone for the life of the program;

            * To end a Matrix behaviour window or Z-Event, you have to
              begin another one. In this case, the duration of the event
              means, "go to these values whenever you find yourself in
              this time period".

            * The end of a Matrix behaviour window or Z-Event does NOT
              mean return to the old values.

    In addition to the start time and end time, there are several other
    decisions you must make when setting up a Matrix behaviour window or
    Z-Event:

              Offset errorlevel? .. The offset is added to any errorlevel
                                    that Opus exits with during this
                                    behaviour window. (Optional.)

              Mail? ............... YES: Opus can make outbound calls
                                    during this behaviour window.

                                    NO: Opus cannot make outbound calls
                                    during this behaviour window.

              Local only? ......... YES: only make calls to systems whose
                                    cost field (set by your nodelist
                                    compiler) is less than or equal to the
                                    "local cost" that you set for this
                                    behaviour window.

                                    NO: it is okay to make calls that cost
                                    more than the "local call" cost that
                                    you set for this behaviour window.

              No Local Mail? ...... YES: do not make calls to systems
                                    whose cost field is equal to or below
                                    the "local cost" that you set for this
                                    behaviour window.

                                    NO: it is okay to make calls to
                                    systems whose cost field is above the
                                    "local call" cost that you set for
                                    this behaviour window.

              #CM ................. YES: only make outbound calls to
                                    systems that are marked as CM in the
                                    nodelist.

                                    NO: outbound calls are not restricted
                                    to continuous mail systems.

              Suppress exits? ..... YES: stop Opus from exiting with
                                    "after mail" exits (set in the BBS.CTL
                                    file) after inbound and outbound
                                    matrix calls.

                                    NO: allow Opus to exit according to
                                    the Matrix exits specified in the
                                    BBS.CTL file.

              Mail only? .......... YES: do not let human callers online,
                                    concentrate on mail.

                                    NO: human callers and the outbound
                                    calls can coexist.

              File requests? ...... YES: let other systems make file
                                    requests on your system.

                                    NO: do not allow file requests on your
                                    system.

              Frequency? .......... A numerical value used to regulate how
                                    often Opus make outbound matrix calls
                                    during this behaviour window. Range:
                                    between 5 and 40 (5= call every 10
                                    seconds approx, 40 = call every 12
                                    minutes approx). (Optional.)

              Local call cost? .... A numerical value used to set what
                                    Opus is to regard as the "local call"
                                    cost during this behaviour window.
                                    Used by the Local Only and No Local
                                    options above. (Optional, but you
                                    should really use it to get the most
                                    out of Opus and make outbound call
                                    scheduling cost effective.)

                       |  Getting the cost information correct is a   |

    During the day (from 06:30 till 20:00 AEST), I have a Matrix behaviour
    window that has LOCAL, #CM, and FILE REQUESTS set to YES. My local
    call cost field for this behaviour window is 10c. I do not want to
    make long-distance calls, and I do not want to call systems that
    cannot handle mail on a continuous basis.

    WARNING            MAIL MARKED AS CRASH WILL ALWAYS BE SENT
    WARNING ===---->>  REGARDLESS OF COST. Do not mark mail as CRASH
    WARNING            unless you really want to make that call NOW!
     
     
    THE MATRIX                                                   Page 111 
     
     
    Back to the example, in my oMMM route control file I might have the
    following lines:

              UNCM 1:119/5
              ONEDIRECT 1:119/5

    So, if I enter a CRASH message to Doug, there it sits, a .DLO file for
    Doug. Although it says Doug's board can accept mail on a continuous
    basis, the COST field in the nodelist for 1:119/5 is $2.50 which is
    above my local call cost field of 10c. It is an international phone
    call.

    Opus will not call 1:119/5.

    At 20:00 AEST, the phone rates are lower. I have another behaviour
    window that allows #CM and Non-local calls. In other words, at
    20:00 AEST I drop the requirement that all calls be local.

    At that point, Opus will start trying to send the mail to Doug.

    Here is how my Z-Events would go:

              Daytime ..... CM, Local
              Overnight ... CM, Non-Local
              ZMH ......... Mail only

    For ZMH (Zone Mail Hour), I drop the CM requirement. That lets Opus
    send to systems that cannot handle continuous mail. The point to all
    of this is that messages stay bundled all the time.  What changes is
    the behaviour of Opus.

    That is about it ...

    At this point, the standard reaction is "I have some special cases
    that this won't handle. I have several pages of routing and batch
    files to do all this special stuff."

    Possibly, just possibly, there are some special cases that Opus
    outbound cannot handle. I cannot think of any. Guido says there are
    none, so do not try thinking any up unless you are fond of grey
    cement shoes and wooden overcoats.



    6.8 SETTING UP BEHAVIOUR WINDOWS

    Set up your schedule of Matrix behaviour windows using those set out
    below as examples of how to control when Opus will make outbound calls
    depending on the cost of the calls. You can fine tune them if you
    want, or add more. The examples below are just meant to serve as a
    realistic guide as to how you should go about setting up Matrix
    behaviour windows.





    Page 112                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    6.8.1 THE ZONE MAIL HOUR

    The theory is, if you cannot get a message to another system at any
    other time, you can send it during the relevant zone mail hour (ZMH).
    One hour is supposed to be set aside for Matrix traffic ... with no
    human callers. Being able to accept traffic during ZMH is the sole
    requirement for maintaining your listing in the FidoNet nodelist. File
    requests are often disabled during the ZMH, although this is optional.

              Tag:             Z (Matrix Behaviour Window)
              Day:             ALL
              Start:           (the start of the appropriate ZMH)
              End:             (60 minutes later)
              Mail:            Yes
              Local only:      No
              No Local:        No
              CM:              No
              Suppress exits:  Yes
              Mail only:       Yes
              File requests:   No (optional)
              Frequency:       15
              Local call cost: not applicable



    6.8.2 OVERNIGHT LONG DISTANCE

    This behaviour window tells Opus that it is okay to make long distance
    calls because rates are low ... but only if the remote systems can
    receive mail on a continuous basis.

              Tag:             Z (Matrix Behaviour Window)
              Day:             ALL
              Start:           00:00
              End:             06:00
              Mail:            Yes
              Local only:      No
              No Local:        No
              CM:              Yes
              Suppress exits:  No
              Mail only:       No
              File requests:   Yes (optional)
              Frequency:       40
              Local call cost: not applicable



    6.8.3 DAYTIME LOCAL-ONLY

    During the day, when long distance phone rates are high, you should
    probably tell Opus not to make any long distance calls.  In fact, the
    only calls should be to local systems that can accept mail
    continuously.

              Tag:             Z (Matrix Behaviour Window)
              Day:             ALL
              Start:           06:00
              End:             23:59
              Mail:            Yes
              Local only:      Yes
              No Local:        No
              CM:              Yes
              Suppress exits:  No
              Mail only:       No
              File requests:   Yes (optional)
              Frequency:       40
              Local call cost: (set an appropriate number of cents,
                                depending on what you have in your
                                nodelist control file call cost table for
                                local calls)

    You should not skip setting the "local call cost"; it is one of the
    main ways of controlling the cost of outbound phone calls made by Opus
    and will reward you in the long run by saving you unnecessary phone
    charges. When Opus implemented the "local call cost" field, Guido now
    sold all his shares in the local phone company. Need we say more?



    6.9 HOW TO GET INTO THE MATRIX

    The term "Matrix" is used to mean the worldwide amateur email network
    that is sometimes called FidoNet<tm>. Although this section describes
    the operation of FidoNet, there is nothing to stop you from creating
    and maintaining your own private nodelist or joining another network
    using FidoNet technology.

    Getting into FidoNet consists of getting a Matrix address. Those
    numbers are assigned by NET HOSTS.

    Normally, you cannot call your net host or log onto his/her system.
    That is not the way this works. Instead, you have to send a message
    requesting an address direct to the Network HOST to prove that your
    system is capable of supporting netmail.

    When your address is assigned, you will be informed of the address in
    a return message from the network host to ensure that you are also
    able to receive netmail.

    By the time you have an address, you will have proved that you have a
    minimally functioning system!  You will have sent and received mail.

    6.9.1 MATRIX STRUCTURE

    The Matrix is a loose collection of fiercely independent systems and
    system operators. To break things down into manageable pieces, the
    Matrix is divided five ways. You will be dealing with the NETWORK and
    NODE items for the most part:

         ZONE      ... a very large geographical area, normally a
                       continent (Zone 1 = North America, Zone 2 = Europe
                       & United Kingdom, Zone 3 = Australia & NZ, Zone 4 =
                       South America, Zone 5 = Africa, Zone 6 = Asia);

         REGION    ... normally a large geographical area, but smaller
                       than a continent;

         NETWORK   ... an even smaller geographical area, often based on a
                       local phone company free/low cost calling area;

         NODE      ... an individual system (you may be a node!);

         POINT     ... a sub-node (you may be a point!).

    Unless you are sending international email, you do not have to worry
    about zones. Zone Coordinators are responsible for overseeing the
    coordination of ZONES.

    Major cities are usually designated as NETWORKS in the Matrix. The
    person who coordinates things in a network is called a Network
    Coordinator (among other not-so-nice things sometimes!).

    The person who oversees the running of the networks in a REGION is
    called the Regional Coordinator.

    A NODE is part of a net or a region.  The person who runs a node is
    you, the Sysop. Your system may be either a NODE or a POINT (if it is
    a point, refer to section 7 of this manual for details of setting up
    as a point.



    6.9.2 MATRIX ADDRESSES

    A Matrix address looks like this:      3:711/401.5

    That is a system in zone 3, net 711, node 401, point 5. Most of the
    time, you will see the shorthand version of that:

              711/401

    The address of a Network Coordinator or "host" system looks like this:

              NET/0

    The host for net 711, for example, would be 711/0.  The zero for the
    second digit is the signal that the address refers to a host.
     
     
    THE MATRIX                                                   Page 115 
     
     
    The address of a regional coordinator looks just like a network
    coordinator's address except that the first sequence of digits refers
    to the REGION not the NET.

    Whatever you do, do not make up your own matrix address; use -1:-1/-1.0
    until you are officially assigned a matrix address.



    6.9.3 FINDING YOUR NETWORK

    Here is how to find the network in your area:

       * Using a text editor or viewer, look at the raw NODELIST.nnn file.
         Search for your city or town -- or perhaps for other phone
         numbers having your area code.

       * Find the line that begins with the word HOST. Here is an example:

         Host,711,SYDNEY_NORTH,Springfield_NSW,Kevin_Mann,61-43-23-2275,
          9600,PEP,MNP,CM

         This line tells you that folks living in North Sydney are in net
         number 711. The Network name indicates this, but may not always.
         If it does not imply a geographical area, check the location
         which occurs before the sysop name.

         If you live in a small town, you may not be in a net. Rural areas
         are covered by regions. If your town is not in the nodelist, do
         a text search for a nearby town or your State.



    6.9.4 ASKING FOR AN ADDRESS

       * Use Opus to generate a Matrix-area message to your network host
         or regional coordinator;

       * Use Opus & oMMM to send your message;

       * Wait patiently for a reply. If you do not hear anything for a few
         days, you might call the host system and leave a local message.



    6.9.5 GETTING ALONG IN THE MATRIX

    Please remember that network coordinators and regional coordinators
    do not get paid elephant dollars or even peanuts. It is a hobby for
    them.

    Getting hooked up to the Matrix can be a frustrating experience
    sometimes. The network coordinator knows that ... he/she had to go
    through it, too!



    Page 116                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    It is OK to ask for help.

    When things are finally running smoothly, you ought to consider
    offering to help. YOU ARE NOT A CONSUMER ... this is a hobby where
    everybody pitches in. There's plenty to do, and no net host can do it
    all. The point is that being in the Matrix is not like subscribing to
    a commercial service.



    6.10 MATRIX FILE REQUESTS

    A file request is when one matrix system asks another matrix system
    for a file. It is something like logging onto the other system and
    downloading a file, but it is handled during a matrix session rather
    than a human caller session and is usually quicker (read cheaper)
    because you do not have to go through the logon sequence and then
    search the file areas for the file you want. Of course, it is only
    really of benefit if you know the name of the file you want in
    advance. File requests can help here too. If you request the magic
    filename FILES, most system will send you a compressed file containing
    an up to date list of files which they have available for request.



    6.10.1 REQUEST METHODS

    There are currently two methods for handling matrix file requests:
    "bark" and WaZOO. "Bark" is a telink-transfer method used by some non-
    WaZOO systems. The WaZOO method uses zmodem and offers more
    capabilities than the older method.

                    Opus will process incoming "bark" style file requests,
    INFO ==---->>   but never initiates such requests. Opus always
                    initiates "WaZOO" style file requests.



    6.10.2 ENABLING/DISABLING REQUESTS

    If you want to allow other systems to make file requests from your
    system, comment this line in the Matrix and EchoMail Section of your
    Opus control file (BBS.CTL) by placing a percent sign % in front of
    it:

              REFUSE FILE REQUESTS

                    See the section called "Matrix Behaviour Windows". You
    INFO ==---->>   can override these control file settings with a matrix
                    behaviour window (or Z-Event).



     
     
    THE MATRIX                                                   Page 117 
     
     
    6.10.3 THE OKFILE LIST

    You will need a file containing a list of files approved for file
    requests. This is a standard, garden-variety text file. It MAY include
    wildcards. Declare the file like this in the "Matrix and EchoMail
    Section" of your Opus control file:

              USES FILEREQ OKFILE c:\opus\okfile.lst

    This is a "raw" list of fully-pathed filenames. Normally, only one
    filename should be on a line. The items must begin in the far left
    column. The format of a normal OKFILE listing is:

    <path\filename> [!<password>]

    For example, you might place the following in your OKFILE:

    c:\comms\*.*
    c:\net\node*.a??
    c:\pascal\tp-tutor.zip
    c:\forth\this.one

    You can also include an optional password like this:

    c:\private\*.* !sesame

    The requesting system must supply the password with the request or
    Opus will not send the requested file if it is in the c:\private\
    directory. Instead, Opus will send the ABOUT file as it does with all
    failed requests. The password is always listed as the second item,
    regardless of the type of request (magic, dollar sign, normal).



    6.10.3.1 MAGIC FILENAME REQUESTS

    Opus also provides support for so-called "magic" filename requests. A
    magic file request is where you "define" an arbitrary "magic" name and
    associate it with a particular file or files which will be sent if
    another system requests the magic name. The format of the OKFILE for a
    magic filename is:

    @<magicname> [!<password>] <path\filename>

    For example, you might place the following in your OKFILE:

    @OPUS120 c:\120\oexe_120.zip
    @OPUS120 c:\120\odoc_120.zip

    =or=

    @OPUS120 c:\120\oexe_120.zip c:\120\odoc_120.zip

    Notice that each line begins with an "at" sign @ to alert Opus to the
    fact that this is a magic file request.


    Page 118                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    You may prefer the first method of putting each associated file on a
    separate, especially if you have 10 or more files being sent in
    response to a magic filename. It makes it easier if an update comes
    through if you do it on a line-by-line basis.

    You can also optionally password protect magic filenames, for example:

    @BETA120 !kinky c:\120\oexe_120.zip
    @BETA120 !kinky c:\120\odoc_120.zip

    Notice that the password is preceded by an exclamation point and is
    the second item listed. The password is always the second item
    listed, regardless of the type of request (magic, dollar sign,
    normal).



    6.10.3.2 DOLLAR SIGN FILENAMES

                                  +-------------------------------+
                                  | The following material is not |
                                  | for novices or the squeemish. |
                                  |                               |
                                  |                     -- Guido  |
                                  +-------------------------------+

    You can execute a .COM, .EXE, or .BAT file from inside your OKFILE by
    using a dollar sign in column one.

    For example, if the remote system does a WaZOO file request for
    "LIST" and your OKFILE contains this line:

              $LIST C:\STUF\GETDIR.BAT %04x %04x

    The `%04x" items are for Opus to use to stick in additional
    information. They are C-Language format symbols. For more info on this
    convention, refer to a book on C.

    The data is available IN THIS ORDER:

          Remote net number (integer)
          Remote node number (integer)

    Future releases might include more than just those two items, so
    anything you do with the data should be protected from additional
    information appended to this list.

    When the LIST request comes through, Opus will bring up a copy of
    COMMAND.COM and try to execute "C:\Stuf\GetDir.Bat".

    The GetDir file could contain this:

          DIR *.ARC > %1%2.DIR
          ECHO ^%1%2.DIR >> C:\OUTBOUND\%1%2.HLO

     
     
    THE MATRIX                                                   Page 119 
     
     
    See what we did? Opus supplied the net/node of the remote system. The
    "%04x" items asked that the net/node be passed as two 4-character hex
    numbers. The batch file did a directory of all the archives in the
    current subdirectory, and piped the directory listing to a file made
    up of the net/node number and a tag of ".DIR". Then we told DOS to
    append or create a .HLO file for the remote system in which the .DIR
    file is listed. In addition, we used a "^" as the first character of
    the listing in the .HLO file as a signal that the .DIR file should be
    deleted after it is sent.

    Another use would be at a zone gateway. You could use this feature as
    a "Directory Assistance" method. Let's say I need to know all the
    systems in Sydney, Australia. I could put this in a .REQ file:

          INFO SYDNEY

    At the gateway, the system could have a customized program that did a
    case-insensitive pattern match on the other zone's node list. The
    system could have this in its okfile:

          $INFO ZONEFINO.EXE %d %d

    "ZoneInfo.Exe" would be the name of the program that searches the node
    list. Note that the ZoneInfo program would have to open up the .REQ
    file. The other system has sent additional information with the
    request ("Sydney"), and this additional information is only available
    in the .REQ file itself. The information is not pulled out by Opus.
    Leaving it in the .REQ file gives your external program the maximum
    amount of flexibility. Anyway, the ZoneInfo program opens the .REQ
    file, looks for "INFO", pulls the next token from the same line
    ("Sydney"), goes through the node list doing a pattern match, creates
    a text file with the requested information, appends a .HLO file using
    the net/node information supplied on its command line by Opus, and
    quickly exits. I said "quickly" because this entire procedure had to
    be finished before ZModem times out. If your external program will
    take more time than is available, you can always just drop DTR on the
    modem to end the session and create a .HLO file so the remote system
    can call back later for the information it wanted.


    Another example, in your OKFILE place the following line:

    $sendlogs !password c:\opus\getlog.bat %d %d

    GETLOG.BAT contains:

    pkzip c:\opus\logs c:\opus\*.log
    omail kill c:\opus\logs.zip -h%1/%2 -poutbound

    This example runs the batch file, GETLOG.BAT, passing the calling
    system's net/node number. The program OMAIL then runs, creating a
    file attach to the calling system, and Opus then regains control and
    then sends the file log.zip to the calling system during that call
    and then deletes the file logs.zip (which is why OMAIL was called
    with the kill command line switch).


    Page 120                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    If you need the information, the original .REQ file will be available
    in your inbound files directory to your external batch file or
    program.

    When Opus sees a dollar sign in the OKFILE, it will immediately call
    the external program/batch file. In other words, if there are any
    actual file requests in the .REQ file following the dollar-sign
    activator, those file requests will be ignored.

    The power offered by the dollar-sign convention is extraordinary. Its
    primary limitations are your ability and creativity.

          The dollar-sign convention offers low-level access to your
          system. Do not use it unless you are sure you know what you
          are doing.                               -- Wynn Wagner III



    6.10.4 THE ABOUT FILE

    The ABOUT file is sent on file requests for "ABOUT," or when a  file
    request cannot be satisfied because the file requested does not exist
    or is not listed in your okfile.lst or its name in the okfile.lst is
    misspelt.


    The ABOUT file should tell the requestor something about your system
    (eg, its main purpose or theme) and perhaps your file requesting
    policy (eg, when file requests can be made, how often, how many etc).
    It could also list any MAGIC filenames (see the section on the okfile
    above).

    Opus sends the ABOUT file if a file request fails. So, you might like
    to explain in the file that it may have been received because the
    file which was requested could not be found or was PASSWORDED (see
    the section on okfile.lst above).

    As you include the extension in the control file, the file can be a
    TXT, DOC, ARC or any other kind of file.


    6.10.5 THE FILES FILE

    If the sysop of another system wants to know what files you have
    available for file requesting, the standard Opus method is to request
    a file called FILES.  When Opus receives a request for FILES, it will
    automatically transmit the file that you have declared like this:

              USES FILEREQ FILELIST c:\opus\filelist.arc

    As you include the extension in the control file, the file can be a
    TXT, DOC, ARC or any other kind of file. However, it is kinder to your
    long-distance and international file requestors to use one of the
    several available file compression programs to compress the file and
    thereby save them a large phone bill. It will also ensure that Guido
    does not send Nunzio around to measure you for those grey concrete
    shoes he makes.

    6.10.6 MAKING A FILE REQUEST

    There are several ways to make a WaZOO file request. You can use
    standalone programs to generate the file request file (########.REQ)
    and then have Opus deliver the file, or you can use Opus together with
    oMMM to generate the file request file.

    The file request file is simply a text file which contains a list of
    the file(s) being requested. Wildcards are allowable. Each filename
    should be on a line by itself. You may add a password after the
    filename using an exclamation point / bang / this sign ! immediately
    followed by the password with no intervening space (for example,
    thisfile.exe !password). The filename is special and looks like this:

              11112222.REQ


              "1111"   ... a four-digit hex number that is the NET of the
                           system that has the files we are requesting.

              "2222"   ... a four-digit hex number that is the NODE of the
                           system that has the files we are requesting.

              "REQ"    ... the file tag that tells Opus this file contains
                           file request information.


    * Opus still knows how to respond to the older "Bark" style method for
      file requests, but it does not initiate such a request.

    * The presence of a ".REQ" file does not make Opus make an outgoing
      call. Only ".?UT" and ".?LO" files cause a phone call.


    To generate the file request file with Opus:

              * enter a netmail message in your Matrix message area to the
                node from which you are requesting the file;

              * put the name of the sysop (or just Sysop) from whom you
                are requesting the file on the To: line ;

              * put the name of the file you are requesting on the subject
                line of the message (and !password, if applicable);

              * invoke the handling menu (in LORE, press enter on a blank
                line - in OpEd, press ^KH) by choosing H and set the
                "Request a file" attribute to YES;

              * save the message (see note below);

              * run oMMM which will create the .REQ file for transmission
                by Opus.




    Page 122                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    The message which you entered, assuming you did enter some "body" for
    it, may or may not also be sent to the system from which you were
    requesting the file. Check your oMMM.CFG file to ensure that the NAKED
    request option is not uncommented. oMMM V1.70 will only create the
    .REQ file if you have NAKED uncommented. The accompanying message (if
    any) will not be sent -- and this means that Opus will not try to make
    an outbound call, although you may force it to do so by POLLING the
    system to which you now have a valid .REQ file waiting to be sent.

    Another way that some grizzled Opus veterans and a certain LCD have
    been known to use to create requests is to use:

     echo nodediff > c:\outbound\00770000.REQ
     echo  > c:\outbound\00770000.DLO

    If you do not understand this method, do not worry about it. When you
    become a grizzled Opus veteran, you will! (You do have to know the
    hexadecimal filename for the destination system before you can use
    this method -- see above for how to work it out.)



    6.10.7 MAKING AN UPDATE REQUEST

    Making an update file request is just as easy as making a normal file
    request. What is an update request? Good question. Oh, you want an
    answer!  It is a request which is conditional on the date of the file
    you are requesting being newer than the copy of the file you already
    have.

    To make an update request, refer to the section above on making a
    normal file request. The method is almost identical, except that you
    set Update Request to YES instead of Request a File and when you enter
    the filename on the subject line, you must give the full path to the
    copy of the file you already have on your system (ie you must type in
    something like c:\files\thisfile.exe rather than just thisfile.exe).

    When Opus calls the other system and transfers the .REQ file, the
    other system will only send you another copy of the file if it is
    newer than the one you already have!

    Advanced Users: note that you can also manually create "update"
    requests which will result in your being sent a file older than the
    one you have (hint: look at a sample update .REQ file and think about
    the time offset specified therein).



    6.11 THE MATRIX MENU

    When Opus is at the ready prompt waiting for a call or the next
    scheduled event, you can get to a special Matrix section.

    Press "M" when you see the "Ready" prompt line. The menu includes
    the following options:
     
     
    THE MATRIX                                                   Page 123 
     
     
    I)nformation:  This generates a chart showing the status of pending
                   outbound traffic and where it is going.

    P)oll:         Force a call to another system whether there is any
                   pending outbound mail or not. If a connection is made,
                   Opus will dynamically generate and transmit a dummy
                   message bundle if a real one is not available.

                   As many as 10 tries will be made. You can stop the poll
                   by pressing <esc>. If no connection is made after
                   several attempts, Opus will recycle to its on-line
                   ("Ready") state.

                   If a connection is made, you can expect all items for
                   that node to be transmitted ... except those marked as
                   "hold" or "left".

                   When you cancel a poll, you may have to press <esc> a
                   few times. The first will cancel the current call; the
                   second one will cancel the poll.

    U)npack:       Process/toss any PKT files found in the current default
                   subdirectory. This does the same thing as the "-u"
                   command line option.

    S)can          Scans the echomail message areas looking for new
                   messages that need to be gathered up into the outbound
                   area.

    C)lear undialables
                   Resets the "unavailable" counter for any boards that
                   Opus has found to be unreachable, so calls may once
                   again be made to them.

    Q)uit          Quits so that Opus goes back to waiting for the next
                   caller or scheduled event.



    6.12 FORCING AN OUTBOUND CALL

    When Opus has outbound traffic but is waiting for a call, you can
    force it to make a call immediately. Simply press "C" when you see the
    "Ready" prompt line.

    If it has any pending mail (not counting "hold" items), Opus will make
    a call. In other words, this does not cause Opus to make a call it
    would not have made, it merely speeds up the process.

    Sometimes Opus will just flicker your modem lights instead of actually
    making a call. This is normal behaviour. Just select C)ALL again.

    6.13 UNSUCCESSFUL CONNECTIONS

    Opus maintains a counter. It is incremented when there is an
    unconsummated connection. Whenever there is a carrier but no
    successful Matrix session, this counter gets bumped.

           +-----------------------------------------------------------+
           | IMPORTANT:  If Opus finds a counter file showing it tried |
           |             five times unsuccessfully to call a node, it  |
           |             will not make any more calls to that node.    |
           +-----------------------------------------------------------+

    You can manually delete a counter file to enable further calls to the
    node in question.

    If you have some kind of daily house-cleaning routine, you could put
    this into your batch file:

              DEL C:\OPUS\OUTBOUND\*.?$?

    The path should be your Opus hold area. It deletes all files that have
    "$" as the middle character of the extension. Every time you use this
    statement, it will re-enable calls to nodes that had unsuccessful
    tries earlier.

    There is also a HOUSECLEANING event which will remove these counter
    files.



    6.14 MATRIX SESSION SCRIPTS

    Instead of (or in addition to) a phone number, the "phone" field of a
    record in the node list can contain the name of a script file. The
    script file name and optional phone number must be in the following
    format:

              "FILENAME.EXT"123-456-7890

    The quotation marks are mandatory; they tell Opus that this is a
    script name. The name within the quotes must be the simple filename
    (no directory path) of a script file in the subdirectory you've
    declared as being the NET_INFO subdirectory. The phone number, if
    given, must be in the format shown. It's used only by the AREACODE and
    PHONE script commands.

    Script names may be easily inserted into the node list by using the
    PHONE and/or DIAL substitution commands provided by PARSELST:

              phone 124/210 "HardWire.Scr"
                   or
              Dial   /   011-
                   1-201- "PCP.SCR"201-
                    ...
                   1-919- "PCP.SCR"919-

    6.14.1 CONTENTS OF A SCRIPT FILE

    A script file is created with a text editor. Each line must contain a
    KEYWORD (refer to the Opus Technical Reference Manual for a fuller
    description of the full list of keywords). In many cases, a script
    file will contain other material.

    The keyword must be in the far lefthand column of each line. The
    system is not sensitive to the case of keywords ... uppercase and
    lowercase are treated the same.

    Some keywords require additional information. You should put a single
    space after the keyword, then start typing the additional information.
    In other words, if you put a keyword then TWO spaces ... the second
    space will be considered part of the additional information.


    Keywords

              Remember: In actual practice, the following keywords
                        must always begin appear in the far lefthand
                        column.


    Xmit:     Send something to the modem.  As in the modem initialization
              string in the control file, Opus understands the following
              special characters:

                        ~    slight pause
                        |    transmit a <cr> character

              EXAMPLE:  xmit ATZ|
                        xmit AT|~ATH0|


    Dial:     Transmit whatever additional information appears on the same
              line of the script, then wait for a modem response.  If the
              modem reports any kind of failure (eg, "BUSY"), the script
              will be terminated.

              NOTE:     The dial "prefix" and "suffix" from the
                        control file are NOT used here.

              EXAMPLE:  dial 555-1212


    Areacode: Transmit the area code portion of the phone number given
              after the script file name, eg:

                   "xxxxxxxx.xxx"@@@-xxx-xxxx

              This is primarily useful for placing PC-Pursuit calls.

              EXAMPLE:  areacode



    Page 126                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    Phone:    Transmit the local phone number portion of the phone number
              given after the script file name, eg:

                   "xxxxxxxx.xxx"xxx-@@@-@@@@

              This is primarily useful for placing PC-Pursuit calls.

              EXAMPLE:  phone


    Pattern:  Designate a text string to be searched for by the WAIT
              command. Up to 4 such text strings, numbered 0-3, may be
              searched for simultaneously. Each string may be a single
              "word" (no embedded spaces) up to 20 characters long.
              Upper/lower-case ARE significant; a pattern will only be
              matched by an identical incoming string.

              EXAMPLES: pattern 0 :
                        pattern 1 OPUS
                        pattern 2           (disables pattern)


    Wait:     Wait for any of the text strings previously designated by
              PATTERN to be received from the remote system. The command
              will continue until either a match is found, or there is no
              input from the remote system for the specified number of
              seconds. The silence timeout defaults to 40 seconds if not
              given. If no match is found the script is terminated.

              EXAMPLES: wait
                        wait 20


    Session:  In most cases, this will be the last keyword in your
              scripts. It means Opus should begin a network session with
              the remote system.

              The session begins with whacking, if necessary. Then it
              moves through the SYNC procedure into the exchange of
              bundles and files.

              EXAMPLE: session


    Dos:      Send a command to DOS. You can process something.or even
              summon a stand-alone netmail session-handler.

              EXAMPLE:  dos DIR
                        dos ARCA test *.pkt


    Carrier:  If there is no carrier when Opus reaches this keyword, the
              script will terminate.

              EXAMPLE:  carrier

    Init:     Go through the normal modem initialization routine.

              EXAMPLE:  init


    Baud:     Set the computer's async port to the remote system's baud
              rate.

              EXAMPLE:  baud



    6.14.2 SCRIPT CHECKLIST

       * Script file names are in quotes in the node list phone field;

       * All script files must be in the NET_INFO subdirectory;

       * Each line must have a keyword in the far lefthand column;

       * Most keywords require additional information. This information
         should be separated from the keyword by a single space character;

       * Most script files should end with "session".

    NOTES:

    Line 1:   Batch file label for "goto opus"

    Line 2:   Ensure we are logged in to drive c:

    Line 3:   Ensure we are in the Opus system directory

    Line 4:   Runs Opus with up to six optional command line switches; you
              would specify these by running the batch file like this:

              NERF BBS

              which would cause the batch file to run "OPUS BBS" when it
              gets to this line.

    Line 5:   The check for errorlevel 255 is not really needed here
              because the following line (errorlevel 8) will end up
              trapping 255. It is put here to stress that 255 is a
              possible errorlevel.

    Line 6:   Checking for errorlevel 8 is a safety measure. It will trap
              any ErrorLevels above 8, too. In other words, the batch
              file is saying "If you get anything else just recycle."

    Line 7:   Respond to "After Edit Exit 7". The errorlevel 7 means
              something in the matrix message area has changed. The only
              thing we need to do is put the new messages into bundles by
              calling oMMM. This errorlevel happens after somebody enters
              a message in the matrix area.

    Line 8:   Errorlevel 3 is a reserved Opus errorlevel. The batch file
              should halt.

    Line 9:   Errorlevel 2 is a reserved Opus errorlevel. The batch file
              should recycle.

    Line 10:  The sysop pressed CTRL-C or ALT-Q on the keyboard to
              terminate Opus and return to the DOS prompt.

    Line 11:  Errorlevel 0 is a reserved Opus errorlevel. The batch file
              should recycle.

    Line 12:  The batch file bundle label used in "goto bundle".

    Line 13:  Runs the oMMM program to bundle and/or compress any new mail
              to be sent to other systems.

    Line 14:  Rerun Opus after bundling any new mail.

    Line 15:  The batch file label used in "goto offline".

       * Quadruple check to be absolutely sure that you have a "TZ"
         environment variable set ... and that your event manager is
         reacting to it well. When your system is waiting for a call, the
         "Ready" prompt message should show information about the next
         scheduled event or behaviour window. See that the time of the
         next event coincides with your expectations. The "TZ" environment
         variable can be a little tricky. See the "Setting Up Opus V1.70"
         section of this manual for full details.

       * Make sure you have an outbound holding area subdirectory;

       * Quadruple check to make sure that both ARCE and ARCA are on your
         path. This may seem silly, but some folks had trouble with it.
         For example, they had changed "ARCA.COM" into "AA.COM" because of
         a patch message archive program;

       * Without both ARCE and ARCE on your DOS path, you can expect
         problems ... tragic and/or humourous depending on your attitude.


    Do this:

       * From the DOS prompt, type ARCE and press Enter. The ARCE program
         should display a help screen. If it does not, do not try to run
         Opus outbound. ARCE must be in the Opus system directory or on
         your DOS path;

       * From the DOS prompt, type ARCA and press Enter. If ARCA does not
         respond with a help screen, you need to put ARCA in your Opus
         system directory or on your DOS path;

       * Put OPUS.EXE into your Opus system directory;

       * Customize the Opus control file, BBS.CTL, and compile it using
         NACL;

       * Compile the raw NODELIST to produce your Version 6 or Version 7
         nodelist files;

       * Build an oMMM control file and oMMM route file;

       * Build a new NERF.BAT batch file.

    7.0 IMPLEMENTING POINT SUPPORT

    Opus can function as either a "point" or in its traditional role as a
    fully-fledged BBS. Starting with Opus V1.70, special point support has
    been added to Opus to make it easy to run Opus as either a point or a
    "BossNode" (usually a fully-fledged Bulletin Board System which
    provides mail facilities points).

    The following sections explain how to set up Opus V1.70 as a BossNode
    to support a PointNet, and as a Point in a PointNet under a BossNode.

    Opus cannot be set up as both a BossNode and as a Point at the same
    time. You can, however, achieve this feat by using two Opus control
    files and switching from one to the other using external events to
    switch the resulting parameter files at the specified times.



    7.1 WHAT IS A POINT?

    A point is the perfect solution if you are heavily into messaging and
    do not have the time or inclination to run and maintain a fully-
    fledged Bulletin Board System. A point is like a small BBS with no
    users other than yourself. It does not require the full time,
    dedicated use of a phone line and its phone number is not publicly
    listed in any list or the nodelist.

    So, what is it really? A point is a computer system which calls a
    fully-fledged BBS regularly to collect any new EchoMail or netmail
    since its last call. The new mail which is collected is then read on
    the point system, "off-line" from the main BBS. The mail collected is
    usually for one person's use only, rather than for general consumption
    as in the case of a fully-fledged BBS where users call into the system
    and read the mail on-line.

    A point does not have to be limited to this use only, it is just that
    the majority do use it this way. For example, a point could be a
    fully-fledged BBS which allows users to call in. The only limitation
    (advantage?) with a BBS point is that it is NOT included in the weekly
    nodelist and does not have to make its system available for other BBS
    calls.



     
     
    IMPLEMENTING POINT SUPPORT                                   Page 133 
     
     
    7.2 HOW DO POINTS WORK?

    You leave Opus running (or to be run automatically) on your computer
    system at a pre-arranged time each day/night (e.g. in the early
    morning). At the pre-arranged time (usually when users are not allowed
    on the BBS), your system will phone the BBS to send all your new
    messages to the BBS and pick up all the new messages from the BBS.
    This should take 2 to 15 minutes at 2400 baud depending on how many
    EchoMail message conferences you wish, or are allowed, to take.

    Opus then sorts all the new messages out into the various EchoMail
    conference topics and waits for you to read them. You can come along
    at any time and read them, and possibly also reply to some of them.
    You no longer need to try calling the BBS in person to read the
    messages, you do not tie up the telephone lines and there are no time
    limits. It makes messaging very easy and leisurely.



    7.3 HOW TO BECOME A FIDONET POINT

    A "point" system is allocated a FidoNet address. This means that a
    person running a point (although not listed in the nodelist) can send
    and receive worldwide netmail, in addition to participating in
    EchoMail conferences. A normal BBS FidoNet address consists of a Zone
    number (Australia is in Zone 3), a Network number within that Zone and
    a node number within that Network. For example, Sentry's full FidoNet
    address is 3:711/409.

    To get a node number in a network (and be listed in the nodelist) you
    need to be able to send and receive mail in the designated Zone Mail
    Hour and comply with the additional mail times prescribed by the
    particular Network in which you are a node. This means that your
    system must be able to be on line a considerable percentage of the
    day.

    This is where points and point operators come in. In FidoNet, points
    are an additional layer in the hierarchy under normal nodes.  A full
    point address is made up of the Zone:Net/Node number of the BBS (known
    as the BossNode) which provides the NetMail and EchoMail service to
    the point plus a point number: i.e. 3:711/409.1 would be the address
    of point 1 under node 409 in network 711 in zone 3.

    The BossNode also usually needs to run special software (eg Opus) to
    ensure that mail from other FidoNet systems is passed on to the point
    to which it is addressed. It should also be noted that not every node
    Sysop is prepared to provide point services to someone wishing to be a
    point. There are many reasons for this. It does involve extra work for
    the Sysop of a BossNode, and it is the Sysop of the BossNode who is
    responsible for the behaviour or "netiquette" of the points under the
    node. In addition, nodes which bear a heavy mail processing burden
    already (for example, Network Hosts and EchoMail Hubs) will usually
    not be prepared to provide additional mail services to points. The
    bottom line is, it is a free service provided voluntarily by the Sysop
    of a node. It pays to ask (nicely!) the Sysops of the FidoNet nodes


    Page 134                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    which you frequent whether they are able or willing to support you as
    a point off their node.



    7.4 SETTING UP AS A BOSSNODE

    The first step is to setup a working Opus BBS, which is explained
    elsewhere in the Opus documentation. Once you have the BBS working,
    it is just a matter of adding a line to your Opus control file.

    An official PointNet number may be obtained from your FidoNet Zone
    Coordinator, but this is not compulsory. You are free to choose
    whatever number your heart desires. To obtain an official PointNet
    number, send a netmail message to the your ZC asking to be allocated a
    PointNet number for your zone. The ZC will then send back to you a
    unique (to your zone) point net number for your use.

    This PointNet number needs to be added to your Opus control file in
    the section titled "MATRIX AND ECHOMAIL SECTION" as follows:

         Address   3:711/409.0        % BossNode's FidoNet address
         PointNet  30141              % Your PointNet number

    It is usually a good idea to put the PointNet option directly after
    your Address option in the Opus control file.

    The PointNet option tells Opus to check any incoming mail from the
    points and strip off the SEEN-BY and Origin lines and put the
    BossNode's Opus system's SEEN-BY and Origin lines in the message
    before passing it on to other systems.

    To send echomail to any PointNet node, is simply a matter of including
    that point's point address (PointNet/Point) in the SCAN line of an
    echomail message area definition in the Opus control file. For
    example (note: this area definition has been viciously edited for
    brevity):

            AREA    0002    DESQVIEW
            %
            PUBLIC MESSAGES ONLY
            ECHOMAIL        DESQVIEW
            ACCESS PRIV     Disgrace
            PATH            C:\MSG\DESQVIEW\
            TITLE           Int'l DESQVIEW Conference [Echomail]
            HELP            C:\OPUS\HLP\ECHOHELP.BBS
            SCAN            711/0 30141/1 30141/2 30141/3
            END AREA

    Opus's support for points has certain limitations. First, you need to
    use Opus to process your incoming packets so that the correct
    addressing is placed in the point-generated mail. This leads on to the
    second limitation. When stripping off the SEEN-BY line inserted by the
    point, Opus does not save this information in the message. If the
    first message in any echomail message area (1.MSG) is subsequently
     
     
    IMPLEMENTING POINT SUPPORT                                   Page 135 
     
     
    deleted and Opus re-scans messages in that area, Opus will send out
    second copies of the echomail messages which originated from the point
    to all the points in your PointNet.



    7.5 SETTING UP AS A POINT

    To setup Opus as a point, Opus needs setting up almost as if it was
    going to be run as a fully-fledged BBS. This includes having a
    nodelist available to Opus to enable it to call its BossNode. Refer to
    the documentation for your favourite nodelist compiler program for
    details of the generation of nodelist files.

    Once Opus has been set up as a BBS system, adding point support is
    simply a matter of adding the BossNode option to the "MATRIX AND
    ECHOMAIL SECTION" of your Opus control file along with the Address
    option as follows:

         Address  3:30141/1.0       % Your Zone:PointNet/Point
         BossNode 711/409           % Your BossNode's address

    The address option is in the form Zone:PointNet/Point. The address is
    supplied by your BossNode. The BossNode is the address of the BBS
    which is called to pickup and send mail too. It does not include the
    zone, it is assumed to be the same as the zone in the address field.

    The address used for a point is generally for use between the point
    system and its boss ONLY. Some Sysops consider it to be "annoying" if
    the address is used to call up their system to plunder its files
    without first getting permission to do so. Other Sysops do not mind at
    all. Be warned!

    The point can receive netmail by using the full address of
    Zone:Net/Node.Point. This is 3:711/409.1 using the above examples.
    Your outgoing PointNet address will be translated by your BossNode to
    this full FidoNet address, and the address on your incoming mail will
    be translated from the full FidoNet address to your PointNet address.

    8.0 IMPLEMENTING UUCP SUPPORT

    While this section of the manual has no intention of providing full
    details on UUCP e-mail, some explanations as applicable to Opus and
    FidoNet are in order.

    UUCP is a Unix-to-Unix copy protocol -- the means by which many people
    on FidoNet communicate with people on other networks such as Internet
    and Bitnet. Several gateways operate between FidoNet and UUCP to
    permit such communication, and these gateways are indicated in the
    FidoNet nodelist by the flag "Guucp".

    Opus-CBCS V1.70 is the first version to incorporate UUCP awareness
    into a FidoNet-compatible BBS program. The Matrix section of any Opus
    V1.70 setup can now be configured to recognise UUCP e-mail.

    It must be stated, however, that this UUCP awareness merely means that
    Opus recognizes UUCP e-mail and can offer certain features to make its
    use much simpler than it has been in the past or with the other BBS
    programs which have netmail capabilities. This awareness does not turn
    an Opus setup into a UUCP gateway.



    8.1  DEFINITIONS

    To help you understand the new Opus V1.70 UUCP features, the following
    is a list of definitions which are used throughout this section of the
    manual:

         Gateway -- a FidoNet system which has installed the UUCP gateway
         software and has registered with the FidoNet domain recognized by
         UUCP;

         From: address -- a path showing how a UUCP e-mail message made
         its way to the destination system;

         Address String -- a stand-alone line of characters containing
         "to:" plus address components (information on who is to receive
         the UUCP e-mail message plus a routing path by which that message
         is exported through the gateway into the proper domain);

     
     
    IMPLEMENTING UUCP SUPPORT                                    Page 137 
     
     
         Address Tag -- a name or some alias on the UUCPlist which points
         to the address components Opus uses to generate an Address
         String;

         Netmail -- point-to-point mail on FidoNet;

         E-Mail -- point-to-point mail on Internet, Bitnet, etc;

         Override -- replace a parameter;

         Cancel -- throw away a parameter



    8.2 ELEMENTARY FIDONET <--> UUCP

    How FidoNet interacts with UUCP depends on your perspective. The
    gateway has a more complicated view of the activity than does a
    FidoNet system served by a gateway. As the UUCP awareness now built
    into Opus has no impact on UseNet newsgroups (backbone echomail
    equivalent), the discussion in this manual concentrates on UUCP
    e-mail, which is the USENET equivalent to FidoNet netmail. Here are
    the basics:

         The host server (often a university) permits a FidoNet system to
         use UUCP for access to networks such as Internet. That FidoNet
         system (the gateway) has installed the software package which
         facilitates this access.

         As UUCP e-mail is imported from the host server to the gateway,
         the software on the gateway determines if that message is to
         remain "local" or be exported to another FidoNet system. If the
         message is destined for another FidoNet system, the appropriate
         zone:net/node address is applied to the message, which is then
         sent out as regular netmail.

         A non-gateway FidoNet system can take advantage of these new UUCP
         features built into Opus V1.70 to enter UUCP e-mail messages,
         reply to them, and send them via netmail to the proper gateway,
         even if the FidoNet system which delivered a replied-to message
         was not the same gateway.

         When a gateway receives FidoNet netmail bound for UUCP, specially
         installed software strips the message of FidoNet kludge lines,
         reads the Address String, and formats the message for use by the
         host server. On the next connect to the host server, the gateway
         delivers the UUCP e-mail.



    Page 138                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    If you plan to use a gateway, please notify the gateway sysop. Some
    gateways serve designated nets only; others serve none. But a gateway
    sysop might be willing to accept in-transit UUCP e-mail if prior
    arrangements are made. Some sysops are charged for connect time to
    their host servers; others are not. And remember that UUCP e-mail
    passing from Internet through the gateway to another FidoNet system is
    traveling as netmail and should be respected as such.

    End of an incredibly basic lesson, folks!



    8.3 DIFFERENCES BETWEEN FIDONET AND UUCP

    When you enter a FidoNet netmail message, you respond to Matrix
    options prompts before entering the editor. When you enter a UUCP e-
    mail message, you respond to many of the same prompts, but your
    responses are different. In addition, some prompts have no meaning.
    For example, you cannot file-attach anything to a UUCP e-mail message,
    nor can you do file-requests.

    When you enter and save a UUCP e-mail message, that message typically
    lives out part of its life as FidoNet netmail; for the other part, it
    is UUCP e-mail. (If you happen to enter that message on a gateway, its
    netmail life span is *real* short.) Thus, you must apply both netmail
    and UUCP e-mail characteristics to your message. During its life as
    netmail, it is sent to a recipient called "UUCP." So, how do we insert
    the real information, such as to whom and where? With the Address
    String.



    8.3.1 THE UUCP ADDRESS STRING

    A message destined for UUCP requires an Address String on line 1 of
    the actual message. It must stand alone on this line with no other
    information, for this string contains data on the person who is to
    receive the message and the path to reach that person. It functions
    like your to/destination of FidoNet netmail, and must begin with "to:"
    followed by address components -- the recipient/destination
    information. It looks something like this:

           to: bevvie@bricks.charm.edu

                      or

           to: host!bricks.charm.edu!bevvie

    It is this critical string which Opus V1.70 takes into consideration
    when you reply to or enter UUCP e-mail.

    8.4 OPUS UUCP FEATURES

    The Opus V1.70 UUCP features work with both the full screen editor and
    LORE. The following is a list of these features:

      o  Default UUCP gateway;
      o  Default Address String;
      o  UUCPlist;
      o  Address String verification;
      o  Address String handling;
      o  Forwarding of UUCP e-mail to Matrix area.



    8.4.1 SCOPE OF THE UUCP FEATURES

    Now that you have an overview, you are probably thinking "when are
    these features appropriate?" or "what can I expect?" Some of the
    explanations here may not be totally clear until you actually start
    playing with the UUCP features.



    8.4.2 CONTROL FILE PARAMETERS

    To take full advantage of the Opus V1.70 UUCP features, certain lines
    of the Opus control file must be set. These lines are as follows:

              MATRIX AND ECHOMAIL SECTION

                     GUUCP
                     USES UUCPlist
                     MESSAGE EDIT Ask UUCP
                     USES VERSION6

              OpEd and LORE EDITOR MENUS

                     ED_UUCP

    GUUCP <zone:net/node.point>

         Tells Opus V1.70 the zone:net/node of the system you have assigned
         as your default UUCP gateway.

         Example:    GUUCP 1:129/104.0



    Page 140                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    USES UUCPlist <path>\<filename>

         Tells Opus V1.70 the location and filename of your list
         containing frequently contacted people and their corresponding
         address components. It is just like FIDOUSER.LST, a list of names
         and addresses. The difference is that UUCPlist is UUCP addresses,
         not FidoNet addresses. If this option is specified, you simply
         enter Netmail messages with the person's name on the address line
         and Opus will look them up in UUCPlist first; if that fails, then
         Opus tries either FIDOUSER (version 6 nodelist users) or
         SYSOP.NDX (version 7 nodelist users).

         Example:    USES UUCPlist c:\opus\uucp.lst

    MESSAGE EDIT Ask UUCP <priv>

         Tells Opus 1.70 the privilege level of anyone who is permitted to
         cancel or override the default Address String.

         Any user below this privilege level will *not* be permitted to
         send a UUCP e-mail reply to anyone other than the individual who
         sent the original message.

         Example:    MESSAGE EDIT Ask UUCP Limited

    ED_UUCP <priv> "<menu option>"

         May be added to the Oped and LORE Menus. It presents the user
         with a display of the selected Address String and a (Y/n)? prompt
         to accept or cancel that string.

         Example:    ED_UUCP Limited "Verify UUCP"

    USES VERSION6

         This line is important for gateways because it tells Opus to use
         the version 6 nodelist, which is recognized by packages such as
         UFGATE. Gateways should uncomment it. The version 7 nodelist can
         be used by non-gateway systems without any impact on UUCP e-mail.



    8.4.3 THE DEFAULT UUCP GATEWAY

    UUCP gateways are flagged in the nodelist by "Guucp." When you want to
    send a UUCP e-mail message, Opus will not waste time scanning the
    nodelist for the nearest gateway; it uses the gateway you have
    designated via a control file parameter. When you do any of the
    following, you trigger Opus to assign the gateway to that message:

      o  Type "UUCP" on the Matrix address line;
      o  Apply the default Address String to your message;
      o  Apply an address from the UUCPlist to your message.

     
     
    IMPLEMENTING UUCP SUPPORT                                    Page 141 
     
     
    Opus does NOT assign the gateway when you type "UUCP" on the "To:"
    line of the Matrix options. Think of "UUCP" as a recipient whose
    FidoNet address is your designated gateway. This gateway can be
    overridden by another FidoNet address.

    If you cancel the default Address String, the message destination
    becomes the originating system (which may or may not be the gateway).

    If you override the default Address String with an address from the
    UUCPlist, the message destination becomes the gateway.

    If you cancel the UUCPlist Address String, the message destination
    becomes the gateway.

    For details, refer to section 8.3.3 (Control File Parameters) and
    section 8.6 (UUCP Procedures) of this manual.



    8.4.4 THE DEFAULT ADDRESS STRING

    This feature works only with replies to UUCP e-mail. Opus does the
    following to generate a default Address String:

      o  reads the "From:" (or "From") address path of a received UUCP
         e-mail message;
      o  uses that line to generate Address String components;
      o  automatically prefaces the components with "to:" ;
      o  inserts the Address String onto line 1 plus a blank line onto
         line 2 of the saved reply.

    Do not look for this string to appear on your message body. It is
    applied to the message after it has been saved.

    For details, refer to section 8.6 (UUCP Procedures) of this manual.



    8.4.5 THE UUCPLIST

    The UUCPlist feature works with both replies and new messages. You
    create a file containing commonly used UUCP addresses. Opus does the
    following when you type an Address Tag from that list onto the Matrix
    address line:

      o  reads the list for the tag's corresponding Address String
         components;
      o  automatically prefaces the components with "to:";
      o  inserts the Address String onto line 1 plus a blank line on
         line 2 of the saved message.

    Do not look for this string to appear on your message body. It is
    applied to the message after it has been saved.

    For details, refer to section 8.3.3 (Control File Parameters) and
    section 8.6 (UUCP Procedures) of this manual.



    8.4.6 ADDRESS STRING VERIFICATION

    As you are accustomed to verifying FidoNet addresses, it is a good
    idea to develop the habit of verifying the Address String. Opus does
    NOT apply the Address String to the message until the message has been
    saved. Depending on how you have selected the string to use, Opus
    displays it in two places.

    It appears above the Matrix options prior to entry to the editor when
    all the following conditions have been met:

      o  the message is a REPLY;
      o  IF AND ONLY IF "Use UUCP Address" is "Yes".

    It appears on the Editor and Handling menus when either of the
    following conditions is met:

      o  UUCPlist is used;
      o  the default Address String is used.



    8.4.7 ADDRESS STRING HANDLING

    Whether the Address String is defaulted or extracted from the
    UUCPlist, Opus permits some limited manipulation of that string in the
    form of a cancellation or an override.

    WHEN YOUR MESSAGE IS A REPLY: Prior to entering the editor, you can
    either cancel or override a displayed Address String via the Matrix
    options. After entering the editor, you can cancel, but not override,
    via the Editor or the Handling menus. At no time, however, can you
    actually modify the Address String Opus has been instructed to apply.

    WHEN YOUR MESSAGE IS NEW: The only feature which produces an Address
    String for a new message is the UUCPlist (defaults are generated from
    replies). This string is NOT displayed prior to entering the editor.
    Neither can it be canceled or overridden from the Matrix options once
    you have chosen to use it. But you can cancel it via the Editor Menu
    or the Handling Menu after you have entered the editor. At no time,
    however, can you actually modify the Address String Opus has been
    instructed to apply.

    For details, refer to section 8.6 (UUCP Procedures) and section 8.7
    (Editor and Handling Menus) of this manual.

    8.4.8 FORWARDING UUCP E-MAIL TO THE MATRIX

    This feature works only with messages having "To: UUCP" in their
    headers, and does not refer to forwarding mail to another system; it
    refers to forwarding a particular message from one message area to the
    Matrix area on the same system. There may be occasions when a message
    destined for UUCP ends up in a message area which does not handle UUCP
    e-mail. In the past, when you forwarded such a message, Opus added
    "from/to/date" information to the top burying the Address String. Opus
    V1.70, however, does not. When the message contains "To: UUCP" in its
    header, Opus withholds adding the "from/to/date" information, thereby
    preserving the Address String on line 1. (Such information is added to
    all other messages, as usual.)



    8.5 THE UUCPLIST

    The UUCPlist is like your own personal "UUCP nodelist". Similar in
    function to Fidouser.Lst, it is a simple text file which contains the
    addresses of individuals you frequently contact via UUCP.



    8.5.1 CREATING THE UUCPLIST

    To create the UUCPlist, simply use a text editor and list one set of
    address components per Address Tag per line as follows:

                  <address tag> <address>

    An Address Tag can be any string of alpha characters: single name,
    first/last names, alias, some made-up name -- whatever you assign. IT
    CANNOT BE ALL NUMERIC.

    You have to create and maintain this list with a text editor. Opus
    does not provide an option by which you can adopt an address from some
    UUCP message.

    When you type a tag onto the Matrix address line, Opus examines the
    UUCPlist for a matching address. If the tag is not found, Opus assumes
    the tag is a name and begins a search in the Fidouser.Lst or
    Sysop.Ndx. If the tag is indeed a name, it might appear in both the
    UUCPlist and the FidoNet sysop list. To distinguish between the two,
    you merely customize the UUCPlist tag, ensuring that it is not
    identical to a name in the FidoNet nodelist.




    Page 144                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    == Example Of A UUCPlist ==

        George Brown brown@fvm.info.com
        Boughman pitt!muswa.dialix.oz.au!wizard
        Pinhead saddam@bunker.blooey.gov
        Martha Garrity xfgt1@csvax.cal.edu
        Uppity Wench freed@nss.fidonet.org
        Digest digest+@luther.ohio.edu
        Vince Smith digest-request@luther.ohio.edu
        Vince vince@luther.ohio.edu

    Now . . . why "Uppity Wench"? Because "Bev Freed" is also in the
    FidoNet nodelist. Therefore, if you wanted to send a FidoNet netmail
    message to Bev Freed, you would type "Bev Freed" onto the Matrix
    address line. But if you wanted to send a UUCP e-mail message to Bev
    Freed, you would type "Uppity Wench" onto that line, because when you
    created the UUCPlist, you assigned "Uppity Wench" as the tag to her
    address components, and thereby differentiated between her FidoNet and
    UUCP e-mail addresses.

    It makes no difference to any UUCP mailer if you do not use the
    person's proper name on the UUCPlist. The mailer does not even know
    about your list. The components of the Address String are what contain
    the critical information.

    Also, notice that the last three lines on the sample list have
    something in common: they are all related to the same system. This
    ability to customize the tag is handy when you contact a person via
    different addresses for different reasons. In this example, Vince
    Smith participates on a private e-mail conference called "Digest." He
    is also the administrator of that conference. Plus, he has another
    address you can use to communicate outside the conference and outside
    his official capacity as conference administrator. You would use
    "digest" to participate in the private e-mail conference. You would
    use "Vince Smith" to communicate to Vince regarding Digest
    administrative matters. You would use "Vince" when you wanted to send
    personal mail that would not be placed in Vince's official
    administrative spool on his system. Set the multiple tags according to
    whatever is best for you.

    By the way ... there is only one legitimate entry on that sample list.
    If you try any of the others, you will learn "The Joy Of Bounced
    Mail".



    8.5.2 FINDING A PROPER UUCP ADDRESS

    There are a few ways to determine someone's proper address:

      o  the person tells you;
      o  you construct an address using the From: address path;
      o  you select the address from the person's signature line at the
         end of a message you have read;
      o  you use a "reply-to" line sometimes added to UUCP e-mail.
     
     
    IMPLEMENTING UUCP SUPPORT                                    Page 145 
     
     
    Keep in mind that a From: address should, but does not always,
    represent the proper path. A machine routing a message on its way to
    you may have discovered that another machine was down. It may have
    rerouted the message via a different machine at that moment. The best
    place to obtain a proper address is from the person with whom you wish
    to communicate. For more information or assistance in determining a
    proper address, contact your gateway sysop.



    8.5.3 VIEWING THE UUCPLIST

    Here is a trick for keeping your UUCPlist handy for viewing even while
    you are in Opus. Add the following line to the Opus control file for
    your Editor Menu (OpEd or LORE or both):

        _SHOW     <priv>     "UUCPlist" = <path>\<filename>

    This line lets you see the entire list while you are in the message
    editor.

    To enable viewing outside the editor, I simply added that line to my
    Sysop Menu as well. If you maintain the list for users too, you might
    want to put the viewing feature elsewhere. Just keep in mind that the
    entire list would be available for viewing by all who had access to
    it. Assign it a security level at least equivalent to that for netmail
    access. Users cannot have separate lists. Opus looks for the filename
    as assigned to UUCPlist in the control file.

    There is one thing to say about viewing the list from the Editor Menu:
    it scrolls by and disappears when the screen is cleared. This does not
    happen when it is viewed from the Sysop Menu. To overcome this
    disappearing act, I added a ^A below the final entry in the list. Opus
    does not care that the OEC is in there. When it hits this command, it
    pauses, giving you a "Press Enter To Continue."

    Another hint: I have installed my text editor (WordStar) to run off
    the Sysop Menu. When, while browsing through UUCP e-mail or
    newsgroups, I find an address I want to add to the UUCPlist, I
    scribble that address down, go to the Sysop Menu, call up WS, edit the
    UUCPlist, save the file, then exit WS back to Opus.

    (In fact, I can edit on the fly many files residing on the hard drive
    while I am still in Opus. Comes in pretty handy when I want to see how
    something looks, create a quick bulletin, etc.)



    8.6 UUCP PROCEDURES

    Now to put this information into practice. The introductory notes and
    feature overviews should give you an idea of what is going on when you
    browse through these sample procedures.



    Page 146                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    BLANK LINES -- Many who use UUCP e-mail are accustomed to inserting a
    few blank lines after posting the Address String onto line 1. Although
    Opus adds a blank line after applying a defaulted or UUCPlist Address
    String to a saved message, it is a good idea to add a blank line or
    two at the top of your message in case you decide to cancel the
    Address String and replace it with one which you manually enter. These
    few extra lines overcome the editor's inability to insert a blank line
    when any text already exists on line 1 of the message body. A blank
    line or two reserves that space.



    8.6.1 USING NO UUCP FEATURES

    This procedure should be familiar to any FidoNetter who has ever used
    UUCP e-mail.


     1.  Type "E" to enter a message.

     2.  Type the gateway's FidoNet address on the Matrix line.

     3.  Type "UUCP" on the To: line.

     4.  Type in your subject then enter your editor.

     5.  Type the Address String on line 1 in the following format:

              to: <address components>

     6.  Add one or two blank lines (optional).

     7.  Enter then save your message.



     
     
    IMPLEMENTING UUCP SUPPORT                                    Page 147 
     
     
    8.6.2 ASSIGNING A GATEWAY

    This procedure can be used when you have no default address and no
    entry for the message recipient in the UUCPlist.

     1.  Type "E" to enter a message.

     2.  Type "UUCP" on the Matrix line.

         Note:  The gateway's address automatically appears, and "UUCP"
                appears on the To: line.

     3.  Type in your subject then enter your editor.

     4.  Type the Address String on line 1 in the following format:

              to: <address components>

     5.  Add one or two blank lines (optional).

     6.  Enter then save your message.



    8.6.3 USING THE DEFAULT ADDRESS STRING

    When you reply to a UUCP e-mail message, Opus offers you a default
    Address String and brings up a new Matrix option special for replies:
    "Use UUCP address." When this option is set to "YES", the default
    Address String will be applied to the saved message.

         VERIFICATION -- The Address String may be verified as follows:

           o  Before entering the editor -- above the Matrix options
           o  After entering the editor -- via Editor or Handling menus




    Page 148                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


     1.  Type "R" to reply.

         Note:  "Use UUCP Address: YES" appears as a Matrix option, and
                "UUCP" appears on the To: line.

     2.  Let the "YES" stand and move to the Matrix address line.

         Note:  When the cursor hits the "Use UUCP Address" line, the
                default Address String appears on the top of the screen
                exactly as it will be applied to line 1 of the saved
                message, excluding any name in parentheses. In addition,
                the FidoNet address of the system which sent the message
                appears. (That system may or may not be the designated
                gateway. The saved message, however, is sent to the
                designated gateway.)

     3.  Type in your subject, then enter your editor.

     4.  Add one or two blank lines (optional).

     5.  Enter then save your message.

         Note:  The saved message goes to the gateway.



    8.6.4 OVERRIDING THE DEFAULT ADDRESS STRING

    Used for replies, this default can be overridden by an address from
    the UUCPlist, or it can be canceled to be replaced by manual entry of
    the Address String into line 1 of the message. When overridden by an
    address from the UUCPlist, the default string displayed at the top of
    the screen is replaced by the address from the UUCPlist, as long as
    "Use UUCP Address" remains set to "YES."

         VERIFICATION -- The Address String may be verified as follows:

           o  Before entering the editor -- above the Matrix options
           o  After entering the editor -- via Editor or Handling menus


     1.  Type "R" to reply.

         Note:  "Use UUCP Address: YES" appears as a Matrix option, and
                "UUCP" appears on the To: line.

     2.  Move to the "Use UUCP Address" line.

         Note:  When the cursor hits the "Use UUCP Address" line, the
                default Address String appears on the top of the screen
                exactly as it will be applied to line 1 of the saved
                message, excluding any name in parentheses. In addition,
                the FidoNet address of the system which sent the message
                appears. (That system may or may not be the designated
                gateway.)

     3A. To Cancel The Default Address String And Use A Manual Entry
         Into the Message Body, do the following:

         a.  Type "N" at "Use UUCP Address."

             Note:  When you set this option to "NO", the ability to
                    override with the UUCPlist and use the designated
                    gateway are also canceled.

         b.  Type in the gateway's FidoNet address.

     3B. To Override The Default Address String With An Address From The
         UUCPlist, do the following:

         a.  Let the "YES" stand and move the cursor to the Matrix
             address line.

         b.  Type the Address Tag as it appears in the UUCPlist, and hit
             Enter.

             Note:  The string which will be applied to the message now
                    appears at the top of the screen. Also, the tag is
                    replaced by the gateway's FidoNet address.

     4.  Type in your subject, then enter your editor.

              If You Canceled The Default Address String, type the
              replacement Address String on line 1 in the following
              format:

                      to: <address components>

     5.  Add one or two blank lines (optional).

     6.  Enter then save your message.

         Note:  If you canceled the default string, the message goes to
                the originating system unless you directed the message
                to the gateway's FidoNet address.

                If you overrode the default string, the message goes to
                the gateway.

    8.6.5 USING THE UUCPLIST

    An address from the UUCPlist can be used to apply an Address String to
    a new message or override the default Address String of a reply.

         VERIFICATION -- The Address String may be verified as follows:

           o  Before entering the editor -- above the Matrix options IF
              the UUCPlist was used to override the default Address
              String

           o  After entering the editor -- via Editor or Handling menus


     1.  Type "E" or "R" to enter a message or make a reply.

     2.  On the Matrix address line, type the Address Tag as it appears
         in the UUCPlist, and hit Enter.

         Note:  The tag is replaced by the gateway's FidoNet address.
                "UUCP" appears in the To: line. If the message is a reply,
                the default Address String display is replaced by a
                display of the address from the UUCPlist.

     3.  Type in your subject and enter your editor.

     4.  Add one or two blank lines (optional).

     5.  Enter then save your message.

         Note:  The message goes to the designated gateway.



    8.7 EDITOR AND HANDLING MENUS

    Two new Opus V1.70 features let you verify Address Strings once you
    are in the editor. They do NOT permit editing. They permit you to
    cancel any default Address String or UUCPlist address. Once you cancel
    the address, you MUST enter the Address String manually in line 1 of
    the message body. For this reason, it is always a good idea to insert
    one or two blank lines at the top of your message body to permit such
    insertion and editing, in case you want to cancel the string after
    already starting your message text.

    When you cancel the default Address String, your message goes to the
    originating system (which may or may not be the gateway). When you
    cancel an Address String from the UUCPlist, your message goes to the
    designated gateway.

    8.7.1 EDITOR MENU

    If you have added ED_UUCP to your editor menus, Opus displays the
    Address String it will apply to the message. The display reads:

                  Use <Address String> (Y/n)?

    If you type "N", the string is canceled. You might consider making
    this option available to your users, if you permit them to modify the
    Subject and To lines of their messages once they are in the editor.
    Remember: the Address String is really a "to" string.



    8.7.2 HANDLING MENU

    A new option has been added to the Handling Menu:

                  G)ated UUCP Address

    When a default Address String or a UUCPlist address is selected for
    application to line 1 of the saved message, this option appears on the
    Handling Menu, displaying the Address String that will be applied,
    excluding any name in parentheses.



    8.8 CREDIT WHERE CREDIT IS DUE

    I personally want to thank Doug Boone for tackling this tremendous
    UUCP adventure. The folks out there who run gateways and the many,
    many people who use UUCP e-mail will benefit greatly from his efforts.
    I also want to thank Trev Roydhouse for asking me to put this section
    of the manual together. And of course, my dearest thanks go out to
    Wynn Wagner III for being Wynn.

    9.0 ECHOMAIL

    An EchoMail Conference is a discussion on a particular topic which
    takes place on a number of FidoNet bulletin boards almost
    simultaneously. A message placed in an EchoMail Conference on one
    bulletin board is "broadcast" to all the other boards in the network
    which are participating in that conference. There are a number of
    conferences available, including international ones, which cover a
    wide variety of subjects. Not all conferences will necessarily be
    available on all FidoNet bulletin boards.

    What EchoMail does for you is allow you to talk to people on other
    FidoNet bulletin boards across the country and the world without
    having to know who, or where they are. You can tell an EchoMail
    Conference Area from the Area Name. It will say something about the
    echo, eg. mirrors, national conference, etc. All you have to do is
    enter a message in one of these areas, and it is automatically sent
    out to any and all FidoNet bulletin boards participating in that
    particular EchoMail Conference.



    9.1 AN ECHOMAIL TUTORIAL

    Before we get down to the nitty gritty of implementing EchoMail on
    your system, it is worthwhile spending a few minutes learning about
    how to use EchoMail. What follows is an edited, and somewhat updated,
    version of a tutorial I grabbed from Jon Sabol's system in 1986. Jon
    was the original author of the tutorial.



    9.1.1 ORIGIN LINES

    At the end of each message in an EchoMail Area there is a line called
    an Origin line which shows the name and FidoNet address of the board
    on which the message was entered. That name may or may not be a
    familiar to you. At the end of the origin line there are two or three
    numbers in parenthesis. This is the FidoNet address of the originating
    bulletin board, eg. EchoMail messages entered on Sentry have an origin
    line ending with "(3:711/401)" or "(711/401)". The "3" is the Zone
    number, the "711" is the network number and the "401" is the node
    number. You can find a listing of all the zone/net/node numbers in the
    entire world in a file which may be called 'NODELIST.TXT' on many
    FidoNet bulletin boards.

    If you wish to send a private FidoNet mail message (not an EchoMail
     
     
    ECHOMAIL                                                     Page 153 
     
     
    message) to a person who has entered a message in a particular
    conference, you can discover the person's FidoNet address by checking
    the origin line on the particular message which he/she entered. If you
    do not know how to send a FidoNet mail message, ask your friendly
    Sysop.



    9.1.2 PRIVATE MESSAGES

    All the messages in each EchoMail Conference area are sent out to all
    the other participating bulletin boards, even if they are labelled
    private. Most FidoNet bulletin board software now only allows public
    messages in EchoMail Conference areas. Beware! If you want to send a
    private message to someone, you should not use an EchoMail area. You
    should, instead, use the FidoNet mail area (also known as the Matrix
    area on Opus bulletin boards).



    9.1.3 PERSON-TO-PERSON MESSAGES

    Generally, person-to-person messages should not be entered in an
    EchoMail Conference. If you have a message for Bill Bloggs, and no one
    else is likely to be interested in it, then use FidoNet mail and not
    EchoMail otherwise the sysop of every bulletin board participating in
    that EchoMail Conference will pay to receive it. A message between two
    users in Sydney, received on a BBS in Perth, is not likely to win you
    any friends. It can be worse! If the particular EchoMail Conference is
    an International one, your message could end up on numerous FidoNet
    bulletin boards across North and South America and Europe.



    9.1.4 THANK-YOU MESSAGES

    If you do receive a flood of replies to a question which you entered
    in an EchoMail Conference, it is only natural to want to thank each
    individual who replied. DON'T do it! Those 15 short one line messages
    saying "Thanks for your reply <fill in the name>" will be echoed
    everywhere and are only of interest to the recipients. You have two
    choices: (1) send a FidoNet mail message, or (2) send a single "global"
    thank-you message in the EchoMail Conference (e.g. "Thanks to all
    those who helped with my modem problem. It is now fixed.").



    9.1.5 OFF-TOPIC MESSAGES

    Every EchoMail conference has a subject; do not stray too far off it.
    Most EchoMail Conferences have a moderator who will step in and shout
    if the topic strays too much. Unless you have been involved in a
    particular conference and have a good grasp of its scope, be cautious
    about entering messages on new topics.

    9.1.6 REPLIES SHOULD STAND ALONE

    When you reply to a message in an EchoMail conference, mention enough
    of the previous message so that readers can tell what you are replying
    to.  It is maddening to see someone discussing the merits of a
    previous message when you cannot figure out what the previous message
    is about. On the other hand, it is equally maddening to see someone
    quote an entire message in reply only to add a short comment like "I
    agree" or "Me too".



    9.1.7 DELAYED REPLIES

    Also, remember the delay inherent in an EchoMail conference. If you
    post a question, don't expect a response tomorrow.  If you reply to a
    question, realise that many others may be replying at the same time,
    and that a flood of messages in reply may pour in over the next
    several days. This will be particularly so in the case of large
    National or International EchoMail Conferences.



    9.1.8 COMMERCIAL ADVERTISEMENTS

    Commercial advertisements are not allowed in many of the EchoMail
    Conference areas. Why should the individual sysops who bear the cost
    of moving the messages around the country, and the world in the case
    of international conferences, pay for your advertising? If you do
    enter a commercial advertisement, you will probably be warned not to
    do so again and your message will be deleted. If you persist in
    entering commercial advertisements in an EchoMail area you can expect
    to have your access to the relevant bulletin board cut off by the
    Sysop. If you are a Sysop, your link to that particular conference may
    be cut.



    9.1.9 COST OF ECHOMAIL

    EchoMail is NOT free. EchoMail messages are sent via local, long
    distance and international telephone calls. Unless sponsored, the
    Sysops involved (particularly the Sysops of "EchoMail hubs" and "host
    systems") bear the cost of this, and so users are NOT charged for
    EchoMail messages [at least in Australia].



    9.1.10 CONCLUSION

    Now, all you have to do to use EchoMail is read the messages in the
    EchoMail Conference Areas and enter or reply to them. EchoMail takes
    care of the rest. Please participate in EchoMail with us. We provide
    this as a free service, and really enjoy seeing it put to use. Enjoy!

    9.1.11 ENCOUNTERS OF AN ABBREVIATED KIND

    In EchoMail messages you are bound to stumble over some of the
    abbreviations listed below. This list is far from exhaustive. It is a
    sample of the abbreviations noted in EchoMail over the course of a
    week.

    BTW      = By The Way
    OTOH     = On The Other Hand
    FWIW     = For What It's Worth
    ROFL     = Rolling On Floor Laughing

    IMNSHO   = In My Not So Humble Opinion
    MYOB     = Mind Your Own Business

    ZMH      = Zone Mail Hour
    LCD      = An Opus Lower Code Dweller
    TNSTAAFL = There's No Such Thing As A Free Lunch



    9.2 HOW ECHOMAIL STARTED

    Once upon a time, way back in 1985, Chuck Lawson (Dallas) and Harv
    Neghila (San Francisco) noticed they were spending lots of time in
    chat with each other ...  running up their long distance phone bills.
    "There's got to be a better way," they concluded.

    "We ought to do something like netmail chat."

    That subject was brought up at the next notorious Dallas  sysops'
    pizza party.  All the sysops had opinions and suggestions, as is
    expected.

    Somebody noticed that Jeff Rush had quietly taken out paper and
    pencil. He seemed to be taking notes.

    The idea was forgotten -- that is, by everyone except Jeff. A month or
    so after the discussion, he popped up and said, "Here 'tis!"

    It was a couple of programs which make up the heart of the EchoMail
    system ... and which had no similarity to any of the designs laid out
    so carefully on our pepperoni conference table.

    He wrote a two programs: SCANMAIL, to move outbound messages from an
    EchoMail area into the netmail message area, and TOSSMAIL to move
    inbound messages from the netmail message area into the EchoMail area.

    We decided to try it out by starting two EchoMail message areas. One
    for sysops, cleverly called SYSOP... one for users called TECH.
    Messages bounced around (most of the time) between systems run by
    Chuck Lawson, Jon Sabol, and Jeff Rush.



    Page 156                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    The next day two other message areas were added: CHATTER and POLITICS.
    Two other systems were added: Wynn Wagner in Dallas and Harv Neghila
    in San Francisco.

    Chuck-to-Harv: the first backbone.  They were spending their long
    distance money again.  Now, it wasn't just for their chatting. It was
    for chatting from Jon and Wynn and Jeff, too... and all they users on
    all five systems.  So it went.

    In short order, other sysops started getting curious and interested.
    The SYSOP area spread out quickly.

    One of the earliest battles was to keep Dallas sysops from talking
    about the most recent picnic or pizza party.  It took quite some time
    for the locals to realize their little local EchoMail area was not
    little or local any more.  <wiping brow> [Ed: Guido's brow?]

    Another early problem was net hosts and region coordinators. Nobody
    realized that the volume of EchoMail would grow so quickly.  At first,
    EchoMail went out like any other e-mail ... through net hosts.  Those
    hosts quickly made it known that they were not amused by the sudden
    increase in their long distance bills.  That seems like a reasonable
    attitude, and everybody agreed that EchoMail would never be "host-
    routed" again.

    "This is going to bring the network to its knees," was the cry from
    some quarters.

    So far, though, it seems to be working.

    The amazing thing is, EchoMail is working in spite of its lack of a
    firm organizational structure. The backbone is an informal coalition,
    and they certainly would not presume to tell you what you can or
    cannot do with EchoMail ... as long as you stay polite. Maybe it
    should be stated like this: EchoMail is working BECAUSE OF its lack of
    a firm organizational structure.

    A quotation from Wynn Wagner III (March 1991):

       "Jeff Rush is sometimes called the person who invented EchoMail.
        That is absolutely not correct. EchoMail was thought up by the
        sysops of Dallas. It happened at one of our pizza parties. Two
        sysops (Chuck/Dallas & Harv/San Francisco) were the first to draw
        up a design document. Jeff was the first to show up with working
        code. I don't want to lessen Jeff's contribution to EchoMail, but
        I need to make sure other toes aren't stepped on."


    ... and a quotation from Jeff Rush (March 1991):

       "In my opinion, the idea of echos was to cause all the little
        pockets of interesting ideas that only a few could find/dial-into
        to multiply into large lakes of discussion others could listen to.
        Specific boards should blur into the whole net, and the item of
        focus becomes the conference itself with its readership, and not
     
     
    ECHOMAIL                                                     Page 157 
     
     
        the BBS with its user base. This provides better dissemination of
        new ideas geographically.

       "Sort of like reaching critical mass and achieving fusion of the
        mind.

       "It means users choose their entry point into the conference based
        on system availability and registration requirements, and prevents
        a sysop from gaining a hold o ideas.

       "I very much object to the (seemingly) natural tendency of people
        to form cliques or clubs, and to withhold membership as a form of
        social control. I see it on the big networks and in technical
        support areas. People let 'friends' into special conferences and
        brag about how they might be able to get you in if you are up to
        their standards.

       "With echos, if the sysop is a jerk but the readership base is
        interesting, you go find another system that carries the echo.

       "Freedom of choice, we carry all flavors ... coke or pepsi or ..."


    You will find several national and international conferences on dozens
    of technical and non-technical subjects ... from Opus to C to Pascal
    to science fiction and genealogy.

    To be involved with an EchoMail conference, you first have to get a
    Matrix address. Although EchoMail is not affiliated with FidoNet, it
    would be impossible to handle EchoMail without FidoNet's Matrix
    structure. If you do not have an address, you need to take care of
    that first.



    9.3 ROUTING AND COORDINATION

    Most EchoMail conferences have a coordinator. Someone who is supposed
    to help with hookups and to keep the discussion on track. Most good
    coordinators are quiet. That is because most EchoMail conferences rely
    on the goodwill and cooperation of participating sysops.

    Some EchoMail conferences are on what's called "the backbone". A
    collection of mostly mail-only systems that do very little other than
    process and send EchoMail.

    Like almost everything else that touches Opus, EchoMail is a
    grassroots sort of deal. It is not a commercial service that has
    subscriptions, and you are not a consumer. If you get involved, you
    can be expected to share in the expense and in the responsibility. But
    that is what makes it a hobby!

               In some Zones, eg Zone 1, EchoMail is never "host-routed".
     --==>>    It is sent directly from one system to another. In Zone 3,
               however, EchoMail is nearly always "host-routed" -- but
    +++++++++  then everything is upside down for us.
    IMPORTANT
    +++++++++  Do not attempt to send an EchoMail conference through your
               Net Host, Hub, Regional Coordinator or ZoneGate Operator
     --==>>    without obtaining their approval to do so IN ADVANCE or
               your career in the Matrix may well be very short-lived.



    9.4 GETTING STARTED WITH ECHOMAIL

    1.      Find an EchoMail conference you want to carry on your system.
            This is all fairly informal. Here are some suggestions:

            * Log onto another local system that carries lots of EchoMail.
              Leave a note to the sysop saying "Hey, can I tie into SUCH-
              N-SUCH on your board?" or "Where can I tie into this area?"

            * Check your net's newsletter or local sysop echo. Many local
              nets publish an up-to-date list of EchoMail conferences.

            * If you hear of some conference that is not available in your
              area, you can put yourself in charge of calling to bring it
              to your area. That is the way EchoMail conferences spread
              out!

            * If there simply is no conference that suits you, find
              another sysop who shares your interest and start your own
              EchoMail conference. That is precisely how conferences
              begin.

            * Do not assume you will get a helpful hand from your net host
              or regional coordinator. Remember that EchoMail has nothing
              to do with FidoNet, and some hosts/coordinators do not want
              anything to do with it.

    3.      Set up an Opus echomail message area definition in the Message
            Areas Section of your control file (BBS.CTL). A sample message
            area definition is given below:

            %
            END AREA
            %

            Make sure you tell the system that the area is for ECHOMAIL
            and that it is to be "PUBLIC MESSAGES ONLY". (It is normally
            considered bad manners to send private messages in an EchoMail
            conference.) Refer to section 2 of the Opus Technical
            Reference Manual for a detailed explanation of the options in
            the message area definition above.

    4.      The Opus control file has some other EchoMail-related options
            which are listed below. Some of the options are designed to
            make EchoMail processing as automatic as possible, or to allow
            the use of an external EchoMail processor. A full explanation
            of these options may be found in section 2 of the the Opus
            Technical Reference Manual.

    5.      Compile your BBS.CTL file with NACL to produce the BBS.PRM
            file which Opus needs to run.

    4.      In your NERF.BAT batch file that runs Opus, set things up to
            run oMMM from time to time, to bundle messages for
            transmission. Refer to the sample NERF.BAT file in Appendix A.


    9.5 THE ECHOMAIL SCAN PROCESS

    The EchoMail scan process is triggered by one of three things:

          * EchoMail messages received through the Matrix. If scanning is
            enabled, the messages are scanned after all bundles are
            uncompressed and tossed. Only the areas that have new messages
            are scanned.

          * A caller entering an EchoMail message, provided you have the
            SCAN ECHOMAIL option in the control file uncommented. If
            scanning is enabled, the messages are scanned after the
            caller's logs off. Only the echomail areas that have new
            messages in them are scanned.

          * Selecting S)can from the M)atrix menu either while Opus is
            sitting at the "Ready" prompt waiting for a call or the next
            scheduled event or as an option off the Sysop Menu (in the
            latter case Opus will wait until the Sysop logs off before
            scanning). This will scan all EchoMail message areas which you
            have defined in your control file.

    Bundles are created as .OUT files in the subdirectory designated as
    your outbound holding area. If you need other processing to take place
    after the scan, you can use the AFTER TOSS EXIT feature. The exit is
    supposed to happen after messages are scanned, whether the cause of
    the scan was the fact that messages came in from the Matrix or were
    entered by a caller. The most likely use for this EXIT will be to call
    oMMM to get the .OUT files into compressed mail archives.

    10.0 USING AN EXTERNAL MAILER

    You can configure Opus V1.70 to load an external mailer after it loads
    itself. The mailer will handle any matrix mail sessions. When it
    detects a human caller, the mailer should exit with a DOS errorlevel
    of baud/100. Opus will automagically trap this errorlevel, set its own
    baud rate and run the BBS for the caller.

    If the mailer exits with an errorlevel other than a valid baud
    rate/100, one of two things will happen:

      *  If the errorlevel = 255, Opus will assume the mailer quit
         (perhaps because you want a human-only window). Opus will no
         longer load the external mailer but will run itself as usual.

      *  In any other case, Opus will exit with the same errorlevel, plus
         the usual Z-behaviour window offset (if any).

    Since Opus remains in memory when the external mailer is loaded, there
    will be no delay between the moment Binkley, or any other compatible
    mailer, exits and the BBS starts.

    Note: With this setup, Opus runs the mailer (eg BinkleyTerm) instead
    of the other way around.



    10.1 OPUS CONTROL FILE SETTINGS

    To use the external mailer option you must define the command to run
    the external mailer in the Opus control file. You must also tell Opus
    whether to use its internal mailer or the external mailer as the
    default mailer. You therefore have to set the MAILER COMMAND and
    MAILER LOAD options in the Matrix and Echomail Section of the Opus
    control file. For example:

              MAILER COMMAND  BT.EXE share    % Run Binkley
              MAILER Load     1               % 0 = Internal
                                              % 1 = Load external
                                              % 2 = Call external

     
     
    USING AN EXTERNAL MAILER                                     Page 163 
     
     
    You should also uncomment the following line:

              REFUSE Inbound Traffic

    which will prevent the following anomalous situation from occurring:

    * the mailer answers the phone, decides that the caller is a human and
      passes control to Opus;

    * Opus decides the caller is a mailer and tries to do a mail session;

    * the caller, a human, disconnects and Opus goes back to the Ready
      prompt instead of taking the "after caller exit" caller and
      reloading the external mailer.



    10.2 EXTERNAL MAILER  SETTINGS

    A couple of notes about using External mailers like BinkleyTerm are in
    order. First of all, you will notice that with Binkley you must use
    the share command line switch to force Binkley to leave the FOSSIL
    driver "hot". Binkley must not deinitialize the FOSSIL driver on exit.
    This will probably be necessary with other mailers which use the
    FOSSIL driver.

    If you use Binkley you should also put "BBS EXIT" in your Binkley
    configuration file instead of using the batch or spawn method to start
    the BBS. This will tell Binkley to exit with the baud rate/100. You
    should use a similar configuration with other mailers.



    10.3 OPUS MAILER EVENTS

    The mailer event is an event which tells Opus whether to use its own
    internal mailer or load an external mailer. The mailer event setting
    overrides the Opus control file setting.

    You can set Opus to use its internal mailer in the Opus control file
    and have a mailer event that will run your external mailer at a
    predetermined time. Or, you can set Opus to use an external mailer in
    the Opus control file and have a mailer event that will run the Opus
    internal mailer at a predetermined time.

    Whenever you have scheduled a mailer event, Opus will use either its
    own internal mailer or the external mailer specified in the Opus
    control file depending on which mailer the mailer event specifies.

    For example, if you have told Opus to use its internal mailer in the
    Opus control file, have set an external mailer command in the control
    file, and have a mailer event scheduled at 1:00am to run the external
    mailer, Opus will exit at 1.00am to the external mailer using the
    command line specified in the Opus control file. The external mailer
    will then run until you set another mailer event telling Opus to use


    Page 164                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    its internal mailer again and exit from the external mailer to Opus
    (ie the external mailer must be set to exit to Opus a minute or two
    after the Opus mailer event is to come into effect).

    Obviously if both the Opus control file and the mailer event agree on
    which mailer to run, nothing will happen. When they disagree, whatever
    mailer the mailer event specifies will override the Opus control file
    setting.



    10.4 OPUS MAILER COMMAND LINE SWITCH

    You can also set an external event that would start Opus with another
    mailer by using the "-M" Opus command line switch. For example, you
    could have a FrontDoor command line set in the Opus control file for
    one mailer event and then start up Binkley with a command line such
    as:

     Opus BBS -M"bt.exe unattended share"

    The -M command line switch will override any setting in the Opus
    control file.

    Note that the mailer's command line is in quotes. This is necessary
    and will cause problems if it is NOT done. You should not put the
    external mailer's command line in quotes when it is specified in the
    Opus control file.

    Also note that there must not be a space between the -M and the first
    quote: Opus BBS -M "bt.exe unattended share" will NOT work properly.

    The -M command line switch will override both the Opus control file
    setting and the mailer event setting and run the specified external
    mailer instead.



    10.5 EXTERNAL MAILER EXAMPLE

    In this example the following assumptions are being made:

    (1) the default mailer is set to the Opus internal mailer;

    (2) the Opus control file has the mailer command set to use Binkley;

    (3) an Opus Mailer event is set to start at 1:00am and use the
        external mailer specified in the Opus control file (Binkley);

    (4) an external event is set to exit Binkley with errorlevel 255 at
        2:00am;

    (5) an Opus mailer event is set to start at 2:00am and use the Opus
        internal mailer;

     
     
    USING AN EXTERNAL MAILER                                     Page 165 
     
     
    (6) Opus has an external event set to exit with errorlevel 100 at
        3:00am;

    (7) the Opus batch file is set, using the -m Opus command line switch,
        to run Opus with FrontDoor as the external mailer if Opus exits
        with an errorlevel of 100.

    In the above set up, if Opus is started at midnight it will use its
    own internal mailer. At 1:00am, Opus will load Binkley. At 2:00am
    Binkley would exit to Opus and Opus would use its internal mailer. At
    3:00am, Opus would exit with an errorlevel of 100 which would be
    trapped in the batch file to run Opus with the -M command line switch
    to load FrontDoor.



    10.6 SCHEDULING EXTERNAL EVENTS

    If you have several external events which run various utilities, you
    will find that having those same events scheduled to be run by the
    external mailer and by Opus will, naturally enough, cause the events
    to be run twice.

    For example, if Binkley (as the external mailer) is active when the
    event is due, it will exit with the specified errorlevel, the
    errorlevel will be trapped, and the programs specified in the batch
    file will be run. Then Opus will restart, and before it loads Binkley,
    it will notice that it has not run the event; so it will run it (with
    the same errorlevel), and the event will be run twice.

    Now why would you do that?  The answer: you want whichever of the
    external mailer or Opus that is active when the event should be run to
    run the event. If the events are not duplicated in Opus, and a caller
    logs on just before an external event, the caller would be able to
    overrun the time when the event should start.

    Two ways of resolving this problems are described in the following
    sections. Refer to the section of this manual describing the Opus
    Event System for further information about events or behaviour
    windows.



    10.6.1 OPTION ONE

    Set up forced "dummy" external events in Opus so that Opus will know
    how much time is left until the next external event. The dummy events
    should all exit with the same errorlevel that is trapped by the batch
    file and simply reruns the batch file.

    Opus will regain control, load the external mailer, the external
    mailer will exit with the appropriate errorlevel (make sure it is not
    a valid baud rate; refer to section 10.0 above), Opus will pass the
    errorlevel on to the batch file, which will in turn take the
    appropriate action.


    Page 166                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    Under this setup, callers to the BBS will not be able to overrun the
    time when the events should occur.



    10.6.2 OPTION TWO

    Set up the external events in Opus as usual; set up forced dummy
    external events to cause the external mailer to exit to Opus shortly
    after (1) an Opus mailer event specifying that Opus should use its
    internal mailer and (2) the Opus external event; set up another Opus
    mailer event specifying that the external mailer should be loaded
    after the external event has occurred.

    The external mailer will relinquish control to Opus which will then
    use its own internal mailer (ie not reload the external mailer) and
    will execute the external event. Opus will then execute the mailer
    event and reload the external mailer.

    Under this setup, callers to the BBS will not be able to overrun the
    time when the events should occur.

    11.0 OPUS SECURITY

    Opus-CBCS has endured as one of the most secure online systems
    available. Opus V1.70 maintains that heritage and adds many more
    features that give the sysop much improved security management
    flexibility.

    Do not feel obligated to use all the features just because they are
    there. It is recommended that you set up your system with moderate
    security features using the privilege levels at first, then take
    advantage of additional features as your needs demand it. The security
    systems for online users are both flexible and potentially complex. If
    you have an idea on how you wish to setup your system, but think that
    Opus security features will not handle it, study them some more. It is
    very likely that you will be able to achieve the desired end result by
    a careful selection and application of the various options.



    11.1 ONLINE USERS

    Most sysops are concerned with flexibility in designing Opus CBCS
    security layout for online users. Opus has four primary adjuncts to
    achieve flexibility -- sections, privilege levels, locks, and
    passwords. These are described in the following section.



    11.1.1 SECTIONS

    Each online user of a system can be allocated a "section" by the
    sysop at logon or can define their own section from the section menu.
    The ability to choose sections from the section menu can, of course,
    be restricted by privilege level and/or by locks.

    A section restricts a user's access to your Opus system. It is used to
    allocate message and file areas, so that a user will only be able to
    access those areas which are included in their allocated or chosen
    section. You can look at sections as being something like TBBS Sigs,
    except that the use of sections in Opus is optional.



    Page 168                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    Sections have a couple of extensions to be considered, MSG_SCAN,
    F_NEW, MSG_NAREA, F_LOCATE and the NextArea/PriorAreas menu commands
    will no longer be concerned with the high message/high file area
    limits. They read the section area table in the user record directly.

    You define the section(s) to which a message or file area belongs in
    the message or file area definition in the Opus control file using the
    SECTION option. The implementation of sections, and user defined
    sections, is treated in detail in the section of this manual dealing
    with ... sections!



    11.1.2 PRIVILEGE LEVELS

    Each online user of a system is assigned a privilege level. This level
    is used by Opus to set many operating parameters. These parameters
    include:

         *    Access to various Opus functions;
         *    Total online time per day;
         *    Total online time per session;
         *    Lowest connect speed that can be used to access Opus;
         *    Lowest connect speed that can be used to download files;
         *    Total file kilobytes that may be downloaded per day.

    Opus has twelve privilege levels:

         Hidden
         Sysop
         Asstsysop
         Clerk
         Extra
         Favored
         Privil
         Worthy
         Normal
         Limited
         Disgrace
         Twit

    In order for a user to have access to a privilege protected function
    in Opus, he must have a privilege level equal to or greater than the
    function's privilege level. For example, most Opus systems will have a
    menu option in the MAIN menu to access the FILES section. If the FILES
    command has a privilege level of FAVORED, then the user must have a
    privilege level of FAVORED or higher to access, or even see, this
    command.

    HIDDEN is a special privilege level. You might think of it as being so
    high that no one can get to it. It is used for hiding a function from
    all users. This would be useful for hiding a menu option to a game
    door that you are constructing. If you set a user's privilege stored
    in the Opus user file to HIDDEN, it will cause Opus to hang up on them
    after they enter their password at logon.
     
     
    OPUS SECURITY                                                Page 169 
     
     
    In your Opus configuration file, you set times, speeds, and file
    download quantities and file upload/download ratios associated with
    each privilege level.



    11.1.3 LOCKS AND KEYS

    The "locks and keys" concept gives the sysop very flexible and
    powerful security management over a variety of functions in Opus.
    Locks are associated with the function and each user has a set of
    keys. There are 32 locks defined. They are denoted by letters and
    numbers as [ABCDEFGHIJKLMNOPQRSTUVWXYZ012345] for locks 1-32
    respectively. If a user attempts to access a function within Opus that
    has locks associated with it, Opus will compare the locks that are set
    against the user's keys to see if there is a match. For example,
    suppose a user has keys A, D, and 3 enabled and wishes to access the
    DOWNLOAD command, which has the D lock enabled.

         User Keys:          [A..D.........................3..]
         Download Locks:     [...D............................]

    The user's key set will unlock the DOWNLOAD command, PROVIDED his
    privilege level is equal to or higher than the privilege assigned to
    the DOWNLOAD command.

    A simple application of locks might be to use them for certain
    meanings. Here is an example scheme:

         D    Download access
         U    Upload access
         E    Enter Message access
         F    File area access
         V    Visiting sysop (use to limit access to certain
              functions and areas reserved for calling sysops)
         Y    YOU - set aside certain functions that only You can
              access

    Use your imagination. Locks and keys give you great control over your
    system.



    11.1.4 PASSWORDS AND BARRICADES

    Opus uses additional password protection to provide yet another level
    of security. Of course, every user normally must have a password to
    log onto your system. A second password feature is the area barricade
    file. Any Message/File area in Opus may have a set of passwords
    associated with it. These are defined in a password file associated
    with that area. The file is a plain text file in the following
    format:

    Password Security_Level           ;comment
    FirstName LastName Security_Level ;comment


    Page 170                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    The ;comment field is optional. Opus stops reading the file after the
    password and security items.

    An example password file for an echomail message could look like this:

    SESAME    ASSTSYSOP ; access for area moderator
    SHILOH    PRIVIL    ; access for those who can enter echomail messages
    GREYSTOKE NORMAL    ; access for those who cannot enter messages
    PERFECT   NORMAL    ; access for those who cannot enter messages
    JANE TRUSTED PRIVIL ; access for Jane who will not be asked for a pwd

    A unique aspect of the barricade file is that it temporarily adjusts
    the user's privilege level to that associated with the password
    entered to gain access to the area. Be sure that the privilege level
    associated with each password in the file is sufficient to pass the
    access privilege level for the area and its associated menu commands.

    Whenever users leave a barricaded message or file area, they lose
    the higher or lower privilege which was conferred on them by the
    password file. As an added security measure, if a user logs off or
    otherwise disconnects while in a barricaded area, Opus always resets
    the last message or file area accessed, as appropriate, to area number
    1 and resets their privilege level to what it was before they entered
    the barricaded area.

    Unlike Opus V1.1x, in V1.70 both message and file areas may be
    separately barricaded by defining a password file associated with the
    relevant area definition in the Opus Control File. Refer to the USES
    BARRICADE and BARRICADE options in section 2 of the Opus Technical
    Reference Manual.

    For further details on implementing barricaded areas, refer to the
    section 3 of this manual on Setting Up Opus.



    11.1.5 THE USER LIST

    The user list may be considered to be a sensitive list on some
    systems. The sysop may limit the availability of the menu option to
    list users by using the locks and privileges described above. There is
    a second method to view the list that is not readily apparent. Opus
    has the convenience of letting you search the user list when posting a
    private message. This helps you to find the correct spelling of the
    person's name that you wish to send a message to. If the user list is
    to be secured, the ability to view it when posting a private message
    needs to be defeated. This is done in the control file by enabling the
    option:

         EDIT DISABLE USERLIST

     
     
    OPUS SECURITY                                                Page 171 
     
     
    The user also has security options related to the user list. He can
    select what portions of information he allows to be displayed in the
    user list by going to the Change menu and turning on or off the
    options. These are:

         List User's Name
         List User's City
         List Last Time Called

    Once again, the sysop has ultimate control. If the sysop does not want
    users to have access to modifying the user list attributes, the sysop
    can disable the Change Menu option for selecting list attributes by
    using privilege levels, locks, or simple omission of the item from the
    menu.

    The Opus command line switch -NL is the same as the Opus Control File
    option EDIT DISABLE USERLIST and will override the control file
    setting.



    11.1.6 OUTSIDE SECURITY

    The REBOOT option in the Opus Control file is a security feature
    which will protect your system from being left in an unknown state
    should you or another caller hangup or otherwise disconnect while
    outside of Opus.

    For example, if the sysop calls in and drops to DOS but loses carrier
    due to line noise, the next caller to the system would find themselves
    at the DOS prompt. Callers who find themselves at the DOS prompt have,
    on occasion, been known to do a lot of damage with a few strategic
    commands like FORMAT E:, FORMAT D:, and finally a FORMAT C:. Of
    course, you could recover from this disaster because you have
    everything currently backed up ... you do have everything backed up?

    Specifying REBOOT in the Opus Control File turns on the watchdog
    function in the fossil driver when a user selects a function that will
    cause Opus to exit with an errorlevel. By turning on this function,
    the fossil will cause a system reboot if the caller is lost while the
    caller is outside Opus.



    11.2 APPLICATION OF ONLINE SECURITY

    This section is devoted to illustrating the application of online
    security measures. To the new Opus sysop, the security options may
    seem like a spaghetti bowl and very confusing. The diagram in figure
    11.2-1 should help you understand the hierarchy of things. Remember
    there are sections, privileges, locks, and passwords. These apply in
    numerous places in Opus. The reason so many places exist is to provide
    maximum flexibility in configuration. There are some basic guidelines
    that you may want to follow:



    Page 172                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


         *    Use sections to restrict users' access to the various
              areas of your system. For example, you could use sections on
              a product support system so that only users with product A
              could access areas with section A set (ie those areas
              dealing with product A).

         *    Use menu command privileges and locks to globally control
              access to things that will apply to the majority of your
              areas.

         *    Use area specific privileges and locks to control those
              things in an area that are the exception to the majority of
              your areas.

         *    If none of the above satisfy your needs, then your final
              option is to build a separate menu file for use in a
              specific area or sets of areas.  This method carries with it
              more maintenance. A separate menu file gives you ultimate
              flexibility in configuring your system, but try to use the
              other Opus facilities first.

    11.2.1 MENUS

    Opus menus are wonderfully flexible for security. You are only limited
    by the types of commands that are allowed in each major section of
    Opus -- MAIN, FILES, MESSAGES, SECTION, CHANGE, HISTORY, SYSOP and
    CUSTOM1-6. You may add and delete commands, change privileges and
    locks, and change the wording of the menus and even the menu prompts.
    The rules for building menus are explained in detail in the Opus
    Technical Reference Manual in section 3 (Opus Menu System). The use of
    privileges and locks on commands is readily apparent, but the use of
    multiple menu files may not quite be so obvious.

    Separate menu files are useful when you have one or more areas that
    need to be treated as "exceptions" to how your menus look for most of
    your areas. Suppose most of your message areas are set to use the
    menus shown in Figure 11.2.1-1. These menus are set in your default
    menu file, ENGLISH.MNU. You also have two genealogy-related
    conferences on your system and would like to make available a database
    program through the menus, when the user is accessing either of these
    conferences. Just define another menu called ENGLISH.001 as shown in
    figure 11.2.1-2 for your genealogy conferences and specify that these
    conferences will use menu number 1.

    11.2.2 AREAS

    It is quite common to have a need for security variations from area to
    area. The first level of security checked per area is the barricade
    password option, if you have it enabled. In Opus V1.70 the barricade
    password for an area is separately definable for each message and file
    section. In Opus 1.1x, the same barricade password applied to the
    message and file area which had the same area number. All area
    associated security options are now independent of each other with
    respect to message and file areas.

    In message areas, you have separately definable privilege levels and
    locks for each of these:

         *    Area access;
         *    Message creation (Enter or Reply or Upload or Upload Reply);
         *    Every external program.

    In file areas, you have separately definable privilege levels and
    locks for each of these:

         *    Area access;
         *    Download command;
         *    Download & Hangup command;
         *    Upload command;
         *    Every external program.

    11.2.3 OPUS EMBEDDED COMMANDS

    Opus embedded commands provide the sysop with the ultimate flexibility
    in customizing system security. There are embedded commands to control
    presentation of text file segments to a user according to privilege
    level and key settings. These are explained in detail in the embedded
    codes section on customizing Opus. With embedded commands, you could
    do things like:

         *    Present a note of explanation, then hangup on a user that is
              relegated to privilege level of TWIT.

         *    Ask a set of questions, then automatically invoke a callback
              validation program.

         *    Ask a set of questions and change a user's privilege level
              with an external program depending on their answers.

         *    Ask a set of questions and add or remove a user's keys using
              the OECs to add and remove keys.

         *    Present access to external program such as online games, but
              do so on the basis of privilege of key settings.

         *    Lock out a mail waiting program to new users based on
              privilege level. Since they are new and will not have any
              mail waiting anyway, it prevents a useless "Check for mail".

         *    Present an AREAINFO file (see section 5 of the Opus
              Technical Reference Manual -- Opus Support Files) in your
              "members" area where you require new users to post short
              biographies about themselves. After the users are validated
              and their privilege is raised, the AREAINFO will not display
              to them based on their elevated privilege level. In this
              way, they can go read the biographies of other users without
              the annoyance of having to read the file that gives new user
              instructions.



    11.3.1 MATRIX AND ECHOMAIL SECURITY

    If a sysop runs matrix and EchoMail with Opus, there may be a need to
    use security measures to protect against unauthorized access,
    unauthorized routing of mail through your system, prevent hostile file
    upload via the matrix, prevent unauthorized pickup of mail, and even
    prevent the insertion of bogus EchoMail into the system. All of these
    things can and have happened in different networks. Opus provides a
    number security measures to help protect you from these attacks on
    your system integrity.



     
     
    OPUS SECURITY                                                Page 177 
     
     
    11.3.1 SESSION LEVEL PASSWORDS

    In order to prevent a node from "impersonating" another node and
    picking up their mail, matrix session level passwords may be
    implemented. Opus supports password matrix sessions with other
    mailers. The password can be up to eight characters long. Opus treats
    upper and lower case characters in the password as the same character,
    i.e., "Password" is the same as "PASSWORD".

    You insert the passwords for the various nodes into your nodelist
    using your favourite nodelist compiler. Refer to the documentation for
    your nodelist compiler for details on implementing this option.



    11.3.2 FILE REQUESTS

    When you set up your system to accept file requests and update file
    requests, you can password certain files in your file request list to
    prevent unauthorized access to those files. This might be useful if
    you are part of a software test team and you want to make new versions
    of the software available in a secure way to your team. See the
    section on file requests in the matrix mail section of this manual on
    how to setup passwords.



    11.3.3 ECHOMAIL

    Unfortunately, there have been instances of EchoMail abuse wherein an
    errant sysop sent inflammatory or bogus messages into a conference by
    sending them to a node in the matrix that carried the conference. Opus
    has protection for this with a feature called ECHO GUARD. You simply
    enable this feature in the Opus control file. With this feature
    enabled, any message received for a conference which does not come
    from a passworded connection, will be tossed into the matrix area and
    marked as an orphan. If you have the PATH BADECHO enabled, the
    messages will be tossed into the bad messages directory.



    11.3.4 INTRANSIT MAIL

    Intransit mail is mail that is sent to your system but is addressed to
    another system. There are legitimate and intentional reasons to do
    this. However, it is hardly welcome, if someone sends mail to your
    system that is destined for a long distance telephone call. If your
    system processes the mail and sends it along, guess who gets to pay
    the phone bill?  You, yourself, you.



    Page 178                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    Opus has protection against intransit mail that you do not want. There
    are four options in the Opus control file to help protect you. They
    are:

         REFUSE All InTransit
         REFUSE Unpassworded InTransit
         REFUSE Nonlocal InTransit
         REFUSE Attribute InTransit

    The function of each of these is explained in detail in the Opus
    Control File Parameters section of the Opus Technical Reference
    Manual.



    11.4 OPUS NAME FILTER

    Opus has its own inbuilt "bad name", "dirty word" or "trashcan" name
    filter for filtering out the undesirable names which some callers to
    your system invariably try to use for their logon name. The filter is
    also handy for stopping that rogue modem which wants to log on to your
    system using your phone number for its name! What? You do not get
    those calls? You will.



    11.4.1 CONTROL FILE SETTINGS

    To use the inbuilt name filter you need to uncomment the USES
    NAMEFILTER option in your Opus control file (BBS.CTL). For example,

    USES NAMEFILTER c:\opus\misc\username.txt

    The precise format for the file "username.txt" is described below.

    There is also another control file option, USES BADNAME, which you may
    optionally use to deliver a custom message to the caller whose name
    has been rejected by the filter, just before Opus hangs up. For
    example:

    USES BADNAME c:\opus\misc\badname

    Note: When you define the filename for the badname message, you do not
    use a file extension. However, the file you define must be an OEC file
    with a BBS extension (ie, the file in the example would be
    badname.bbs).

    Do not forget to recompile your BBS.CTL file with NACL after making
    these changes!

    11.4.2 FILTER NAME FILE FORMAT

    The filter name file contains a sequence of lines that are interpreted
    in one of two ways, depending on the first character:

              ? ... the material that follows on this line is not
                    to appear in any form in a caller's name

                    EXAMPLE:  ?shit

              ! ... the material that follows on this line is not
                    to appear AS IS in a caller's name.  This is a
                    case sensitive filter.

                    EXAMPLE:  !Ass


    Remember that Opus converts all names to an uppercase character
    followed by lowercase characters.  In the first example, the character
    sequence "shit" would be disallowed in any form in a caller's name.  In
    the second example, "Ass" would be thrown out ONLY if it appears as
    the first Three characters of a caller's first or last name.  The reason
    for the second (case sensitive) version is this: the characters "ass"
    appear in several legitimate names.

    One other special character is available: the hash sign or American
    (not English) pound sign. Opus will convert a hash/pound sign to a
    SPACE character. This lets you further refine your list of banned
    words for caller names.

              EXAMPLE: ?All#

    After all, you do not want to keep everybody named "Allison" off your
    system just because you are trying to keep folks from logging on as
    "All".



    11.4.3 BEHAVIOUR OF THE FILTER

    Opus will go through the file defined by the USES NAMEFILTER option on
    a line-by-line basis after an unregistered caller types his/her name.

    If Opus finds a problem, it will either:

          (1) pretend that you run a PRIVATE system that requires pre-
              registration and hang up on the caller after sending the
              message "This is a Private system."; or

          (2) If you have defined a badname message file, Opus will show
              that file to the caller before hanging up.

    Problems include a match with any item in the USERNAME.TXT file ... or
    some DOS I/O error in reading the file.

    11.4.4 ERRORS IN THE FILTER NAME FILE

    The name filter is really an idiot when it comes to error recovery. It
    assumes that if you are using the filter, you know how to use it.

    Here is an example, if a line in the name file begins with some
    character other than "?" or "!" then the entire line is ignored.
    There is no error message.

    In a nutshell, if you decide to use the filter you need to be sure you
    are using it correctly because the system's primary job is that of a
    filter ... not a tutorial on its usage.



    11.4.5 SPECIFIC EXAMPLES OF USE

    Set out below are a few specific examples of how to use the inbuilt
    name filter. These are all taken from a working filter file that has
    not been modified in months, so you should not encounter any
    unexpected problems.

    Note: each item should appear by itself on its own line, starting in
    the far left column. The setting out in the following sections is to
    save space.



    11.4.5.1 ONE LETTER NAMES

    To prevent callers from using one letter names, you need to have the
    following in your name filter text file:

    !A#
    !B#
    (all the way to)
    !Z#



    11.4.5.2 ROGUE MODEM NAMES

    To prevent those rogue modems from logging on to your system, you need
    to have the following in your name filter text file :

    ?atd             ?+            ?4          ?8
    ?atz             ?1            ?5          ?9
    ?atdp            ?2            ?6          ?0
    ?atdt            ?3            ?7

    11.4.5.3 SHY CALLER NAMES

    Some callers are _very_ shy when it comes to revealing their real
    name(s) to Opus. Here are a few of the more common shy personalities
    for your name filter file:  ?test  ?qwer  ?asdf  ?visitor



    11.4.5.4 DIRTY WORD NAMES

    You will have to supply your own, but here are a few pointers. The
    following entry will prevent anyone using "Xxxx" as a first name,
    middle name or last name:  !Xxxx#



    11.4.5.5 WANNABE HACKER NAMES

    Ever since 1986 when Fido V11w was in vogue, there have been the
    wannabe hackers who try to log on to a system as "All", "Anyone" and
    "Everyone" and then merrily proceed to go through the message areas
    deleting messages. Of course, with today's volume of EchoMail this may
    no longer be the major disaster it once was! To spoil their fun, add
    the following to your name filter file:  !All#  !Anyone#  !Everyone#

    What about ye olde "Hacker" who calls?  You may have to handle this
    case carefully. A quick check of the Sydney metropolitan telephone
    directory reveals about a dozen people listed with that surname, so it
    is not necessarily a good idea to lock out "Hacker" with:  !Hacker#
    unless you are sure either that (1) you will not get any calls from
    legitimate Hackers, or (2) you do not want any calls from anyone with
    that name.

    12.0 OPUS FOLKLORE

    Opus has attracted its fair share of ... "Guido, put that bat down
    NOW!" ...



    12.1 THE ELUSIVE NERF.BAT

    Ever wondered why the batch file commonly used to run an Opus-CBCS is
    named NERF.BAT ?

    Well, here is how it all began ...


       "From: Wynn Wagner III
        Subj: RE: Nerf.bat

       "DEEP BACKGROUND.

       "It started here at work on my first project in C. I'm an old
        assembly language jockey, and I was having some trouble with C.

       "I used to take the white "K-and-R" book on C (that's kind of the C
        Bible), put it on the floor, and jump up and down on it.

       "My manager at the time bought me a nerf HAMMER and told me to use
        it on the book so I didn't cause quite so much damage. She also
        said this:  "I was going to get you a nerf bat, but I figured the
        hammer was more business-like."

       "I still have the hammer in my office. I still use it sometimes.
        The "K-and-R" book was worn out years ago.


       "NERF FOR OPUS.

       "I did some of the docs for Opus 0.0. [Editor's note: it was the
        V1.00 docs] On a lark, I stuck in "nerf bat" in the "Required
        Equipment" list.

       "I mean, it's for hobbyists.  There wasn't any requirement to be
        businesslike, so the bat made more sense than the hammer.

     
     
    OPUS FOLKLORE                                                Page 183 
     
     
       "The 0.0 docs were full of junk like that: quotes and leg-pulling
        and on and on.  There's a difference between being serious and
        being solemn.  The 0.0 docs were serious, but they weren't very
        solemn.


       "MISSING THE WHOLE POINT.

       "Somewhere along the way, somebody did some docs for Opus called
        NERF FREE.  As far as I can tell, about the only thing these
        'unauthorized' docs did was remove the humor.

       "Nowadays, the Opus ByLaws And Covert Action Committee requires
        humor for Opus documentation, so that kind of nonsense won't
        happen again."


    ... and the list of required hardware in the Opus V1.00 documentation
    read:


       "Required Hardware

       "Standard equipment for Opus consists of:

             AT-class computer with Award BIOS
             72-Meg hard drive
             One each:
                  TeleBit Trailblazer modem (9600 bps)
                  U.S.Robotics HST modem (9600 bps)
             Amdek 722 EGA monitor
             PC DOS 3.3
             Mirror sunglasses
             Nerf bat

       "That roughly describes Wynn's computer setup. It is the only one
        that carries any sort of assurances. It is:

             -={ Opus will sometimes run on Wynn's computer }=-

       "No other assurances are made. All other equipment is officially
        classified as Non-Standard."




    Page 184                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    ... and then there was THAT message in the MEADOW:


       "From: Jim Beeler
        To:   All
        Subj: Nerf.bat

       "I have a friend at work who I am helping set up an OPUS BBS for
        his company located in Tokyo, Japan. Being Oriental, he possesses
        infinite patience and, unlike his American counterparts in the
        U.S., realises the importance of following instructions to the
        Letter.

       "He began installing OPUS utilising the OKITs. Soon he discovered
        the missing items: Mirror Shades and a NERF Bat. Realising that
        these must be necessary items, he pulled out his sunglasses. The
        nerf bat, however, was another problem. Not realising exactly what
        a Nerf Bat was, but none-the-less realising that if it was in the
        documentation it must be necessary, he searched through the .ARC
        files for further references to the elusive Nerf Bat. Finally, he
        figured it out!

       "He called me over to his computer to see the installation of OPUS
        that he had done ... from the "C:\" prompt he evoked NERF.BAT and
        up came OPUS.

       "So, for those of you that have trouble locating a Nerf Bat, take a
        lesson from a wise Oriental, just rename your RUNBBS.BAT to
        NERF.BAT.

        Jim."


    ... and now you know what, hithertofor, only some of us really
    grizzled Opus veterans were privy to.



    12.2 IDENTIFYING THE CHICO CONNECTION

    You can tell someone from Chico by two words, "fir" ("I'm going fir
    some beer.") and "ahmund" ("We knock the 'L' out of them." You have to
    see the way almonds are harvested to get it.)
                                                   -- From a conversation



    12.3  oPOL0: OPUS POLICY, VERSION ZERO

    (pronounced "oh-pahl'-oh")

    This is the official policy statement of WOC: The Worldwide Opus
    Consortium.


     
     
    OPUS FOLKLORE                                                Page 185 
     
     
    12.3.1 DRESS CODE

    WOC sysops must wear mirror shades.



    12.3.2 ATTITUDE

    There is a difference between "serious" and "solemn".

    Any WOC sysop caught being solemn will be referred to the Enforcement
    Squad of the Opus ByLaws and Covert Action Committee for a
    solemnectomy.

    Any WOC sysop caught being sirius will be sent to Bob Klahn for
    technical support.



    12.3.3 BACKBITING, SNIDE REMARKS, AND ON AND ON

    Any WOC sysop who backbites, or makes a snide remark to another WOC
    sysop, or who on-and-on's will be forced to memorize the entire set of
    GBS/BBS embedded commands.

    Note that the "snide remark" clause only refers to other WOC sysops.
    It's okay to snipe at non-WOC sysops.



    12.3.4 MATRIX

    If you run netmail, you gotta run Zone Mail Hour.



    12.3.5 TRANSIENTS

    If you accept "In Transit" messages, you can't delete or change the
    content unless it would be illegal for you to transmit the messages.

    If you do delete or change messages, your title is "editor" instead of
    "host."  Because WOC doesn't have a title anything like "editor",
    deleting or changing a message is the same thing as resigning as host.

    The change clause does not apply to software which adds "Via" or
    "SeenBy" or other automated festooning for reasonable technical
    purposes.





    Page 186                      OPUS-CBCS V1.70 SYSOP OPERATIONS MANUAL 


    12.3.6 RULES IN A NUTSHELL

       Rule #1: Don't take yourself so seriously.
       Rule #2: Run Zone Mail Hour.
       Rule #3: Don't delete or change "in transit" messages.
       Rule #4: Send code.



    12.3.7 ENFORCEMENT

    Except where noted, this is a codification of Natural Law.  It is not
    necessary to account for enforcement of such things as the National
    Mail Hour in the same way as it isn't necessary to enforce the Laws of
    Gravity.

    It is like there is no need to make a law that says "All bachelors
    must remain unmarried."  That would be silly.  When a bachelor gets
    married, he's simply not a bachelor any more.  When a system doesn't
    run Zone Mail Hour, it isn't running net-mail. It's very simple and
    straight-forward.

    Enforcement of the Unnatural Laws, such as wearing mirror shades, is
    absolute.  It is now a standard that any WOC software incorporate
    enforcement procedures.  For example, when entering chatmode, WOC
    software will produce a brilliant flash on the monitor that could
    result in eye damage to anybody not wearing mirror shades.



    12.3.8 DISCLAIMER

    Membership in WOC doesn't preclude membership in any other
    association. WOC is neither for or against anything or anybody, and
    never takes a stand on any issue (except mirror shades).

    12.3.9 MERIT BADGES

    The following merit badges are available to WOC members:

             * Continuous Mail...

                      WOC AROUND THE CLOCK logon certificate

             * 386-based mail system...

                      WOC DON'T RUN gbs file

             * WOC system carrying more than 50 echomail areas...

                      WOC ON THE WILD SIDE ribbon

             * New WOC sysop...

                      OUT OF THE SKILLET INTO THE WOC badge

    Penalties for improperly displaying a WOC badge or honor gbs file are
    too severe to even mention.

    Here are the MEADOW "rules" posted by the moderator (aka the Uppity
    Wench ... don't ask!):


    From: Bev Freed
    To:   All
    Subj: Meadow Rules

    Guess what?  It's that time of the month again: MEADOW ADMINISTRIVIA!

    TOPIC:  Meadow is for the discussion of Opus problems, the future of
    Opus, Opus utilities, suggestions, ideas, and support among Opus
    sysops.  It is involved in the technical operation of Opus and
    responsible to the Opus Bylaws and Covert Action Committee.

    PARTICIPANTS:  Opus sysops ONLY!  Definitely UNAVAILABLE to users.
    While sysops of other systems are welcome to READ Meadow, they can't
    expect answers to QBBS, TBBS, Fido, or whateveryourerunningthisweek.
    That would be off-topic.

    RULES:  In addition to general rules for any conference, Meadow rules
    are simple, standard, and may be bent a little, but not trashed.  The
    Meadow "spirit" is one of cooperation.  And remember: Guido is
    watching.

    1.  Keep your messages on-topic --
        On occasion, the Moderator may get the feeling that message
        content is inappropriate or has the potential to attract a barrage
        of inappropriate messages.  In such instances, the Moderator will
        post a reminder of the rules or send netmail.  It's not personal.
        If you post an off-topic message, let it be for comic relief and
        the fostering of friendships.

    2.  Be excellent to one another and keep your sense of humor --
        Personal attacks (thinly disguised or not) are prohibited.  The
        useful exchange of information requires you to accept that people
        have opinions or experiences which contrast yours.  The object of
        this conference is to learn from others, not argue with them.

    3.  Be helpful --
        If you can help someone with a technical problem, PLEASE do, but
        avoid blind guesses.  You'd be doing a disservice.  If you're not
        certain of a proper response, wait a few days to see if someone
        out there has the definitive answer.  Then everyone learns
        something.

    4.  Never use Meadow to reply to inappropriate messages --
        If you feel a message is inappropriate, simply take a deep breath
        and ignore it.  It'll go away.  And if it doesn't, LET THE
        MODERATOR HANDLE THE PROBLEM.  If you feel particularly strong
        about a specific posting, send the Moderator private netmail, or
        take your beef off-echo and flame the person directly.  Leave the
        others out of it.  The Moderator has probably already addressed
        the problem via netmail.

    5.  Keep your quotes to a minimum --
        People read Meadow regularly; you don't need to quote and explain
        the obvious.  If you get a bad case of quotitis, the Moderator
        will come over to administer something you hated as a kid.

    6.  Keep your messages public and without nuisances such as
        encryption, encoding, or rotation --
        If you have a driving need to send a private or fancy message,
        there's something intriguing out there called netmail.  Use it.

    7.  Keep to a minimum BBS ads and notices on new conferences or toys--
        Such advertisements and so on should be restricted to no more than
        ONCE per month.  We hear ya, already.

    HANDLES:  While not encouraged, "handles" or anonymous names are
    permitted provided they are not used with the intent to conceal the
    identity of a person posting malicious, annoying, or illegal messages.
    Please include your proper name someplace on every message.

    NONCOMPLIANCE:  If you cannot abide by and comply with the rules, you
    are requested to forego posting messages to this conference.  Anyone
    who posts inappropriate messages will be warned of the infraction.  If
    such postings continue, you will be asked to drop the conference.  If
    you do not drop the conference voluntarily, the system(s) uproute will
    be asked to disconnect your feed.  This method of keeping the Meadow
    interesting and productive is not preferred.  It is preferable that
    participants simply abide by the rules and "spirit" of the conference,
    and that they serve one another.

                          NOTICE ON OPUS DEVELOPMENT

    Opus isn't something you slam in and let 'er rip.  It's an ongoing
    project which means it's ALWAYS under development.  It's fostered by
    the entire Opus community -- Lower Code Dwellers (LCDs) as well as
    Opus sysops and grizzled veterans -- within an environment of
    participation, cooperation, and above all, PATIENCE.  The list at the
    bottom of this notice changes as needed to address many of the
    complaints/requests in Meadow.

     
     
    MORE INFORMATION ON OPUS                                     Page 191 
     
     
    BUG/SECURITY PROBLEMS:  In the course of all human events, we
    encounter problems.  And so it goes with Opus development.  When you
    feel you've encountered a real nasty bug or security problem, send
    your reports via DIRECT netmail to 1:119/25 or 1:129/104.  Otherwise,
    use Meadow.  Someone out there has probably already solved your
    troubles.

    NEW RELEASES:  Please don't ask when the next version of OPUS will be
    released.  You'll always receive the standard answer:  WHEN IT'S
    READY.  The LCD's maintain Opus as a hobby.  It isn't a full-time job
    for anyone.  No one is making money from this.  After the beta and
    gamma testers have had their chance to break Opus, the new(est)
    version will be released for everyone.  Please be patient.  And when
    it's ready, you'll hear it on Meadow first.  :-)

    SEND CODE:  If you have a suggestion, try to provide as complete an
    explanation/model/example/source-code as you can.  Even a chunk of
    BASIC code is better than nothing at all.  Send code to Doug Boone at
    119/25.

    SEND DOCS:  If you have a good explanation of how to handle aspects of
    Opus or integration of tricks and utilities, please share them.  Send
    docs or a note that you have them on hold to Trev Roydhouse at
    3:711/401 (PEP) or 3:711/501 (V32).
