   This software product is a collection of easy-to-use facilities that
   enables management of a bank of items.

   An item is declered by the following details: Its title, List of authors,
   place and date of publication, several keywords identifing the item, and
   an abstract.

   The main features are:
   ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀
   *  Adding data to a new item (and thus adding an item to the bank of items).
   *  Updating data of an existing item.
   *  Deleteing an unneeded item from the data bank.

   *  Searching for items that meet a specified combination of keywords.

   *  Printing a bibliographical list for all or some of the items.

   *  Maintaining the system.




   Following are the key strokes convensions for the system:

   Setting the drive and path for data files to be searched.
   The structure is:    [ <drive letter>: ][ <path> ]

   Use this option to process data files other than those in the default
   directory (i.e. the directory from which XR was activated).
   The two parts are optional. It is, however, recomended to enter
   a complete path (including drive) even if the drive is not changed.
   Note that when specifying a path, the '\' sign must close it.
   A blank line will reset to the default drive.

   Examples:
   ▀▀▀▀▀▀▀▀▀
 * C:                   if XR was activated from anywhere in drive c:,
   this is simmilar to a blank entry - resetting to the default directory.

 * A:\FILES\XREF\DBF\   process files from drive a: in directory
   called DBF that is a subdirectory of XREF that is itself a
   subdirectory of FILES.

 * \MYDIR\              process files from the drive you are in now,
   in directory MYDIR that is a subdirectory of the root directory.
   If no .dbf's are found in the requested directory, the request is ignored.


   This window enables the customization of the colors in a colored
   monitor environment, or the customization of the screen attributes
   in a monochrom monitor environment.

         The screen areas that may be color-customized are : -

              *     The normal foreground,
              *     The normal background,
              *     The bold foreground, and
              *     The bold background.



   Use the Up and Down arrows to navigate among the screen areas.
   Use the Left and Right arrows to change the color for the selected
   screen area. The entire screen changes its color after each selection.

   After setting the colors, you may press the Esc key which will
   reset the colors to those before the entrance to the colors window,
   or you may press the Enter key which will activated the selected
   colors.

   In order to track the data that is entered to the PUBLICATION and
   KEYWORD fields, and to prevent mistaken data in these essential
   fields, the data that is entered to these fields has to be familiar
   to the system.

   Keying an unfamiliar word in one of these fields (or pressing the F1 key)
   prompts a table window from which you may choose a familiar word to be
   transfered to the field.
   This is also helpfull in data entry : key in the first letters of
   a long keyword, press enter and transfer the complete word from the window.
   In order to add a new word to the table - press the F10 key.
   From this point - the added word is one of the familiar words to the
   system.

   In the window you may use all the navigation keys, in order to
   place the cursor on the word you wish to transfer to the field.
   The last line in the window holds the word or portion of word
   you entered in the field. The cursor is placed in the window on
   the closest word to the one entered. Altering this word (by keying
   in characters) will respectively replace the cursor.



   This is the main import window. Importing external data means
   adding new articles to the system, from a file previously created by
   any data net. Data from this file is transfered, via given rules of fields
   determination, in the "cut and paste" concept, to the XREF.
                                DATA FILE
                                ▀▀▀▀▀▀▀▀▀
   This is the name of the data file that was previously created by a
   data net. You may use wildcards (* and ?) or leave that field blank
   in order to activate a selection window.
                                 PROFILE
                                 ▀▀▀▀▀▀▀
   This is the name of the file that holds the rules via which the
   data in the data file is being treated.
   If you enter here a name of an existing file, the system prompts
   you with the 'Updating the existing profile ?' question. The default
   is no (N/n), but you may responde with a Y/y and edit the profile.
   If you enter here a name of a new file - the editor is being automaticaly
   loaded.
   Once the system gets the names of an existing data file and a profile -
   the import process begins.
   Whenever an unknown Publication or Keyword is found in the data file -
   the process stops, and the user is asked to determine weather this word
   is to be replaced with another, or is added to the table.
   The required parameters (all found and kept in the profile) are : the item
   length, the begin_of_item and end_of_item identifiers, the delimiter of
   the list of keywords, and the identifiers of the data fields. The first
   four are entered in the first (left low) window, the begin_of_item in the
   left upper window, and the end_of_item in the right upper table window.
   The item length should be grater than zero only for fixed format items !!
   The end of item should be entered only if there is a special identifier for
   the end of item. It should be left blank when the end of an item is
   indicated by the beginning of the next item.
   The format of each delimiter is :  ±Col1 , Delim , ±Lin , ±Col2      where
   Col1     is the column at which this delimiter should be found in the line,
            in order to be a delimiter,(0 means every column is good)
   Delim    is the character string to point the begining/ending of the field,
   Lin      is the number of lines to be skipped from the delimiter, and
   Col2     is the number of columns to be skipped .

   For example: a Begin_Title of 5,TITLE:,2,0 means that whenever the string
   TITLE: is found in the fifth column of a line - two lines ahead starts a
   title to be transformed to the XREF.

   While the begin of item is unique, the end of item consists of a list of
   delimiters. XREF looks for the first delimiter to be found, and this becomes
   the actual delimiter for this field.
   This window is available in the Search and List screens to enable data
   sorting. Up to four fields may become control fields :
                Publication, Date, Volume and Page.
   The sort is allways performed in accsending order.
                            Order Setting
                            ▀▀▀▀▀▀▀▀▀▀▀▀▀
   The sort window allowes five options. The first four are fields that
   may be selected as control fields, and the last one uses to activate
   the sort request. Select the field names in the order you want them
   to perform as control fields. Selecting a field name to be a control
   field, is marked with a number neer its name. This number illustrates
   the place of that field in the sort order. Note that you may cancel a
   field mark by selecting it again. The mark disappears and the field is
   no longer a control field. You may then select it again with its new
   relative mark.
   When sorting by the date field, dates as 17/06/89, JAN 90, 1/89, 07/87,
   july' 89 - are treated correctly. All other formats are treated as blanks.
                         Natural Order Setting
                         ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀
   In order to restore the original order - select the sort request
   without any control fields selection. This will cause the data to
   be sorted in its original order.

   This window is available in the Search and List screens to enable data
   filtering. You may declare the range of data to become active.
   Two fields may be filtered : Publication and Date.
                             Main window
                             ▀▀▀▀▀▀▀▀▀▀▀
   Use this window to get to the publication or date filtering prompt, or
   to restore the original scope of data, by selecting the RELEASE option.
                        Publication filtering
                        ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀
   Selecting the first option prompts you with a window to declare the
   publication name you wish to browse. When activating this filter,
   only items with publication names that are equal to the entered
   publication will become active. Entering a wrong publication name will
   prompt the table window, to enable a correct selection.
                           Date filtering
                           ▀▀▀▀▀▀▀▀▀▀▀▀▀▀
   Selecting the second option prompts you with a window to declare the
   From-date and To-date boarders. When activating this filter, only items
   with dates that are equal or grater than the From-date and equal or
   smaller than the To-date will be active.

   Notes: 1. Lower and Upper cases are ignored.
          2. If the To date is empty - it defaults to the value of From date.
