It's nice to have readers. Eleven numbers is out and i'm slowly getting some mail or notices about my magazine. Hope that sometime will also come more articles from some other peoples. Thanx for all of few which were coming. What's new on my side of world? It's simple. The Netherlands is on autumn very rainy country. Raining and raining. It's far better to leave my portable at home, otherwise it will get a swimming. My company is now moved into new office in different building (thanx God, that we were moving only from one side of street to another). Never want to move again, it's something really terrible, but it's far better. New cabling for network, telephone lines for centrale, all of those needed changes and new things were taking about week. That's also reason why so long pause between last editorial. Company is faking busy thing and business has importance before hobby (otherwise hobby will not get money for existance, but i guess, it's known problem). During this time of movement i got several nice programs like QEMM 6.0 with Desqview 2.40 (it's really very nice), DMAKE which i hatched in ClipperNet and which seems far best MAKE program which i ever seen (40lines RMAKE make file was shutted down into about 10 lines only with this DMAKE...). Therefore at this moment is evening and i'm sitting at home (it's now exactly 00:59am) and writing this editorial after long playing with mentioned DMAKE. TV is trying to satisfied watcher with "BLACK WIDOW" thriller which is as usual totally loosing action and only giving nice women faces (as common). How it's coming to make and publish this magazine? It's very simple. I'm continuosly collecting interesting texts which i see somewhere, then i'm continuosly writing sometime new articles. Scanning of all ClipperNet files, testing and writing descriptions, then extracting from my database of BUG reports, collecting sometime articles from other authors (it's not happening very often). Then i'm starting program which i'm developing and which is using collected texts to make one big magazine. Every friday it's going out with some mail robot and messages to ClipperNet, PDN and persons who are asking for Hold putting of every issue. Then articles for made number are totally gone. One can see how they are flowing out and if there is too less of them, must write new ones.... Simple, isn't? Of course yes if there is valid one condition. Enough time. Still (it's now 5 minutes later than latest mentioned time ) i'm too mad to stop this, especially when i see a good future and fact that it can help to you or anyone else. Let stop sentimental talking , see you again on our pages...

This means that a dCLIP.EXE engine built with RTLINK will support all the features of RTLINK .AND. all the features of dCLIP. 2. Dynamic overlaying of C/ASM code is tricky and can cause undesirable results when the code includes data or interrupts. CLIPBBS 1-12 Page 3 12 Nov 1991 3. RTLINK seems to have occasional problems with Clipper-code static overlays when the modules pass parameters. 4. BLINKER allows the SET CLIPPER= to be burned into the .EXEcutable program. 5. dCLIP, dCLIPRUN use the SET CLIPPER= for free pool memory allocation and the OBJMemory= in DCLIP.SYS for object pool allocation. 6. If using Incremental Linking option or pre-linked libraries then speed is improved. 7. Symbol reduction is accomplished by compiling your .PRGs into fewer large objects, then dynamic overlaying at the procedure level. 8. Memory packing in RTLINK/Clipper-5.0 is unnecessary due to the garbage-collection system designed into the Clipper libraries. ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ Choosing a Linker for your Clipper Projects ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ Selecting a linker to use for a Clipper application is not always an easy task. There are many factors which must be considered before deciding which is the very best possible solution. Then again, it may not be necessary to always choose the best linker, but simply a linker which is adequate and will solve the problem with the least effort. To help you decide, I have chosen to use 6 real case studies, in which our staff had to make a choice of a linker or linkers for our different Clipper projects. Case Study #1: FYI - Work Smarter (ALINK and BLINKER) FYI - Work Smarter is a Clipper application that is almost entirely written in Clipper with a few functions from several third-party libraries (GET-IT, Overlay(), SMARTMEM, IDL). When development started on Work Smarter, about 1-1/2 years ago, the product was linked using PLINK86 and 4 "static overlay" areas. As the product evolved, memory usage went up. No matter how we managed the overlays, the symbol table grew to the point where we had to use a new linker to get more memory. We purchased ALINK, a "dynamic-overlay" linker and with only a few hours effort reduced the memory overhead by 50k. ALINK dynamically overlays ONLY Clipper-compiled .OBJ files. This was not a problem for us since this project was "Clipper- code" intensive. With a little more effort and by compiling our application into CLIPBBS 1-12 Page 4 12 Nov 1991 larger and less .OBJects we reduced the symbol count further and were successful in reducing the memory overhead an additional 30k. A total investment of about 24 hours of time and $179.00 reduced our .EXE load module from 340k to 260k. ALINK likes to fragment the Clipper memory pool and we were getting OUT OF MEMORY during re-indexing, so we invested in a product named SMARTMEM and made structured calls to the H_PACK() function which packs the free pool. As FYI - Work Smarter evolved, it grew more powerful and larger. The .EXE load module increased another 10k over several months and we were running into memory problems again because now the program was designed to work with a 90k resident TSR. Enter BLINKER, (designed by Jud Cole, the author of ALINK). BLINKER uses the same basic overlaying concept as ALINK, however it offers the ability to also dynamically overlay the EXTEND.LIB library. This brought the .EXE load module down from 270k to 230k. Our BLINKER link file: FILE hoa,swapattr,resident OUTPUT fyi.EXE BLINKER MEMORY PACK 10 BLINKER OVERLAY OPSIZE 50 BLINKER EXECUTABLE CLIPPER V10;R32;F39 SECTION INTO fyi.OVL BEGINAREA FILE errorsys FILE hoaovl1.OBJ FILE hoaovl2.OBJ FILE hoaovl3.OBJ FILE hoaovl4.OBJ FILE hoaovl5.OBJ FILE hoaovl6.OBH ALLOCATE overcl.LIB ALLOCATE dclip.LIB ALLOCATE extend.LIB ENDAREA LIB dclipr,getit,smartmem,clipper,idl Case Study #2: FYI - LetterWriter (.RTLINK and .RTLINKplus) FYI - LetterWriter is a Clipper application which is a data- merging word-processor, spell-checker and thesaurus. FYI - LetterWriter is approximately 30% Clipper-compiled code and 70% C/ASM code. When this project started, about 1 year ago, it was linked using PLINK86 and 5 "static overlay" areas. After many "crashes" we determined that this application was far too sophisticated to be managed with "static overlays", so we purchased .RTLINK, reduced our overlay areas from 5 to 3, and completely eliminated computer lock-up problems while reducing CLIPBBS 1-12 Page 5 12 Nov 1991 the .EXE load module by 50k. The Clipper-code portion of the program was still overlayed "static" so we had to be careful to structure the Clipper-code segments properly to prevent lockup, however the C/ASM code was all automatically reloaded simply by entering the command: "RELOAD FAR 300" in our link file. We tried using dynamic-overlay linkers like BLINKER and WARPLINK for this project, but they could not dynamically overlay the sophisticated C/ASM routines we used in the spell checker and thesaurus. During development we use RTLINK+ because it supports Microsoft Code-View, then we link the final product with RTLINK 3.1. Our link file: Sorry, but this is information is proprietary Case Study #3: dCLIP/dCLIPRUN (.RTLINK and NOLINK 2.1) dCLIP is a development platform and runtime system for Clipper which runs Clipper applications from .OBJect files or dynamic libraries. dCLIP is basically a Clipper application, however, the dCLIP.EXE program contains about 5% Clipper-compiled code and 95% C/ASM code. The dCLIP dot-prompt interpreter, debug system, database manager, report writer, query-builder, etc. are all written in Clipper, yet none of this Clipper-code is included in the DCLIP.EXE program, but instead is included in a "dynamic-library" which is linked into memory only as the functions are needed. dCLIP and dCLIPRUN are an example of 2 linking technologies working together to produce the very best memory management solution. NOLINK is a "dynamic link" library which is linked into the dCLIP.EXE "engine" using .RTLINK. The engine also includes the entire CLIPPER.LIB and EXTEND.LIB libraries and makes provisions for including any third-party libraries. When dCLIP development started 2 years ago, we used PLINK86 and NOLINK version 1.2. Our dCLIP.EXE engine load module size was approximately 310k. This left very little room for the Clipper application so dCLIP version 1.0 could handle only small Clipper programs or it would run out of memory. Like ALINK and BLINKER, the NOLINK-1.2 "dynamic linker" used the Clipper free pool to link the Clipper-compiled code. This caused memory fragmentation and eventually the program would run out of memory. dCLIP 2.0 used a whole new approach to the problem of overlay linking. First, we threw away "static overlays" and found that we could extract modules from the CLIPPER.LIB and EXTEND.LIB libraries and overlay them using .RTLINK and the "MODULE" command. The Clipper libraries are all C/ASM code, so we use the "RELOAD FAR 200" command to insure that the overlayed CLIPBBS 1-12 Page 6 12 Nov 1991 segments get properly reloaded. RTLINK allowed us to overlay the "dynamic-link" functions from the new NOLINK-2.1 library as well, so now our DCLIP.EXE load module was reduced from the original 310k to only 230k. With this additional 80k memory overhead, rewriting the "dynamic-linker" to allocate a seperate object pool and including a "memory-packing" utility for memory defragmentation, we improved dCLIP to now be capable of running any large Clipper application without running out of memory.

What i have to do for correct using of 4DOS? Answer: 1) take a sure, that CONFIG.SYS contains correct specs: shell=c:\4dos.com /e:512 /s:d /p This one is telling to boot that has to take 4DOS.COM instead of COMMAND.COM with 512 bytes for environment and swapping to disk (replace with /s:e for EMM swap) /P is telling to run AUTOEXEC.BAT for start of system. 2) AUTOEXEC.BAT has also to set several things: path c:\;c:\4dos Be sure that PATH is telling where to found all other files from 4DOS! set COMSPEC=c:\4dos.COM set 4DSHELL=/S:D First one is giving correct COMSPEC for all invocation of COMMAND.COM like later and other is telling again about swapping for all other copies of 4DOS.COM later. This two things are needed for DOS to get correctly working, for CLIPPER here is needed something totally different. Clipper is taking COMSPEC DOS variable to run 'command.com', then will RUN without problems any internal or external DOS commands or another programs. If one wants to run another session of 4DOS.COM, then for compatibility is best to use RUN("%COMSPEC%") which is without problems. And last comment - ONE MUST HAVE ENOUGH MEMORY TO RUN _TWO_ coppies of 4DOS.COM in case of running another 4DOS.COM or copy of 4DOS.COM + runned program. ------------------------------------------------------------------------------ QUESTION: I'm looking for good books about Clipper 5.0x and also looking for some newspapers about it, where i can found some from them?

I can create a dbase, but when I go to enter data, DBU hangs. No response from keyboard... nothing! Running an AT (286) 10hz V/c drive VGA. (Can't see any probs there) Is there a fix I should know about? Answer: You are completely right. Nantucket produced changed DBU but this change is putting in DBU new error which wasn't in previous version. Here is a fix (one from many): at line 281, change DBUEDIT.PRG to say: /* Edit the current field */ IF bof() .and. eof() .and. !lAppend keyboard chr(K_DOWN) + chr(nextkey()) loop ENDIF ------------------------------------------------------------------------------ QUESTION: I encounter very often a very annoying problem which i refer to as "ghost records". With no apparent regularity i find in my .dbf files, usually but not always at the end, one or more records whose fielsd are filled with right arrows (chr(26)'s). For sure this problem is a very well known one; Can someone tell me the origin of these records and how to avoid them ? (I use clipper 87 and am starting with clipper 5.1. The ghost records are visible also with dbxl interpreter and enter in the total number of records of the fields). ANSWER: Sounds like a dBase III pack of a clipper .dbf file. Or header corruption where there is one more record in the filesize than the header says. Clipper reads the real filesize and gets the last record which is full of end-of-file markers (^Z or ASCII 26). Solution : don't access the files from dBase or DBXL. (I do it often though and only stop doing it when problems arise - which has not happened for a year or so now). ------------------------------------------------------------------------------ CLIPBBS 1-12 Page 12 12 Nov 1991 ============================================================================== ANOMALIES ============================================================================== ANOMALIES and their comments This part of Clipper BBS Magazine is dedicated to all discovered anomalies and comments about them in Clipper products. Because Nantucket is still unable to give own bug and anomalies reports (as actually did in past with Summer 87 version) is very handy to have results of many investigations done on many user places. I'm also doing my own investigatings, because i'm always very good when someting has hidden problems. Everything what i buy will first show all problems and then all normal things. This amazing part of my live is sometime making me crazy, but for testing of programs it's great . Daniel ------------------------------------------------------------------------------ DBEDIT()* Locks up with return value of 2. Problem Statement When a UDF returns a value of 2, DBEdit locks up. --------COMMENTS--------- Long time i was trying to get situation where DBEDIT will hang up with return value of two. I did it with simple program: ³ #include "inkey.ch" ³ ³ use adres ³ dbedit(0,0,maxrow(),maxcol(),,"ufun") ³ ³ function ufun(mode,ind) ³ do case ³ case mode=4 ³ if lastkey()=K_ENTER ³ return (0) ³ endif ³ if lastkey()=K_ESC ³ @ 0,70 say 'Ctrl A' ³ return (2) ³ endif ³ case mode=0 ³ @ 0,0 say '+-+' ³ return (1) ³ otherwise ³ return (1) CLIPBBS 1-12 Page 13 12 Nov 1991 ³ endcase ³ return (1) All is working perfect and actually few of other mine programs (old ones) with DBEDIT are using also RETURN (2) very often. And they haven't problems at all. If someone knows about sample which will cause REAL hang, please give it to me. Daniel ------------------------------------------------------------------------------ DOS 5.0 Using PLL's with DOS 5.0. General Comment If you encounter a problem executing an application.EXE and you are using a PLL try: a) LOADFIX App b) Re-making the PLL file under DOS 5.0 c) Executing the application from a batch file which 'eats up' some of the memory in the first 64Kb segment; e.g., @echo off command /e:32000 /c %1 %2 %3 %4 %5 %6 %7 -----------GENERAL COMMENT------- It's well known problem of DOS 5.0 when used with DOS=HIGH because it's leaving first 64KBs free for application and application is then starting in first 64KBs. This is making some problems for some applications. And it's not ONLY problem of CLIPPER. Dos 5.0 has many problems with many other applications. Some from them are caused by wrong written appli- cations, but some other also with some "incompatibility" of new DOS to previous versions. .DD. ------------------------------------------------------------------------------ DOS ERROR 4 Encountered on a network. General Comment If you encounter DOS Error 4 on a network, check that your SHELL.CFG file has a sufficent number of files specified. Without a FILES= statement, the default will be 40 (Novell). ------ADDITIONAL COMMENT------- Formulation and placing of this 'comment' between other anomalies of Clipper are not very good choosen. Because it's problem only of not enough knowledge of programmers writing applications for NOVELL. It's common knowledge that Novell application can open FROM NETWORK CLIPBBS 1-12 Page 14 12 Nov 1991 only 40 files if is not specified bigger number inside of SHELL.CFG. I saw several people saying with flames "CLIPPER IS NOT ABLE TO OPEN MORE THAN 40 FILES IN NOVELL, I READ IT IN REPORT FROM COMPUSERVE". It's pitty and big mistake and is giving big misunderstanding. .DD. ------------------------------------------------------------------------------ CLIPBBS 1-12 Page 15 12 Nov 1991 ============================================================================== COMMENTS ============================================================================== How to use 4DOS for managing projects More on the theme of zipping and unzipping whole work areas to save on disk space... These two let you put a whole directory branch away into a zip when you aren't working on them. The zip is in the same place that you otherwise find the directory so the main structure is constant. The usual sequence is: cd \projects open hoover .... do hoover stuff close This works better with an alias like: alias job=cd \projects ^ if not isdir %1 open %1 _______________________________________________________________ :: This is used from the directory containing the zip alias open=unzip -n -d %[1].zip %[1]\ ^ cd %1 _______________________________________________________________ :: close.bat :: Fold current or named directory and subs into a zip file :: one level higher. :: Remove files and directories folded loadbtm on :: use argument if present if not "" == "%1" cdd %1 :: Touch the directory to ensure pkzip has :: something to do. Avoid Error #12. echo %_date >zip.log :: zip it up set fspec=%[_cwps]*.* set zspec=%[_cwp].zip set dspec=%_cwp zip -urp %zspec %fspec iff errorlevel == 0 then cd .. call prune %dspec echo OK: %fspec ZIPped into %zspec else echo *** Error %? *** ZIP of %fspec Failed. endiff CLIPBBS 1-12 Page 16 12 Nov 1991 set fspec= set zspec= set dspec= ------------------------------------------------------------------------------ CLIPBBS 1-12 Page 17 12 Nov 1991 NOTICE of some older articles second time After long thinking new decision is born. Sometime Clipper BBS Magazine will do a REPRINT of OLD articles from old numbers if they are interesting or in any way useful. This decision is based on possibility that no everyone has available old numbers and maybe can easily get present ones. Therefore it can be handy to have them now. Therefore if you see that article is TWICE in Clipper BBS Magazine, nothing bad. It's purpose.

Programs and sources of pushing SYSTEM timer connected function into CLIPPER. If someone needs to display system CLOCK on screen whenever hee is, then take this and use this! However, still the same problem is appearing as in call cases of redirection of interrupts. This one is using INT8 to redirect and this MUST be changed BACK to original, otherwise will come mailfunction of system. Thanx to gap in Clipper which isn't allowing simple this way and is able just jump out without ANY executing of some user closing function. Therefore in case of crash of Clipper program will redirection stay in place at all. However, great idea is born and can have nice future. ------------------------------------------------------------------------------ CLIPBBS 1-12 Page 20 12 Nov 1991 ClipperNet - GETKEY.ARJ File Name: GETKEY.ARJ Other Names: File Size: 280,043 bytes File Contents: DEMO.EXE 430080 DEMWPRO.TXT 1727 DEMOGET.SPT 1702 EKOT.TXT 139 DEMOLD.PRG 22591 EMPH.TXT 63 DEMOMAIL.PRM 21 EXP.TXT 279 DEMOMAIL.SPT 1204 GETKEY.LIB 102723 DEMOMAIL.TXT 637 GETKEY.OBJ 15560 DEMOPEN.MEM 9226 GETKEY.PRG 31147 DEMOPEN.PRM 23 KARTIS.DBF 6226 DEMOPEN.SPT 1166 MANUAL.DOC 71128 DEMWPRO.PRM 21 PSOURCE.LIB 29237 DEMWPRO.SPT 2390 TI.CH 9488 TI_MSG.DBF 24971 TI_DEFLT.DBF 18761 TI_MSG.NTX 2048 TI_DEFLT.NTX 2048 From first moment of discovering, this looks as one good library oriented for FIELD INPUT in professional manner and ideas.
