Pascal Runtime Error 200 Fix
The patch has background information in German (TPPATCH.DOC) and English (TPPATCH.ENG). Furthermore on even faster computers than today this patch will fail and the run time error will re-appear even with the patch applied. ctbppat v1.2 © Andreas Stiller [April 2000]ctbppat fixes programs coded in Borland Pascal that cause runtime error 200 on systems with clock speeds of over 200MHz. This “bug” seems to pop up in DOS based programs that were faster than 200MHz and could make an already slow machine even slower and/or inoperable. weblink
Already built programs won't be changed. Now recompile the CRT.PAS file, and put it into the TPL files using TPUMOVER: TPUMOVER TURBO.TPL -CRT TPUMOVER TURBO.TPL +CRT Optional replacement delayloop.

If PatchCRT does not work for you, you might check if the EXE file is compressed, eg using PKLITE, LZEXE, etc. (To do so, you'll probably need to analyse the internal before the changes: cs:0062 33C0 xor ax,ax cs:0064 A25100 mov [0051],al cs:0067 A26100 mov [0061],al cs:006A A26200 mov [0062],al cs:006D 40 inc ax cs:006E A25000 mov [0050],al after the changes: cs:0062 So the 'divide by zero' error message isn't really correct.
We recommend upgrading to the latest Safari, Google Chrome, or Firefox. Or you can used a patched run time library that contains a lot of additional changes that nobody has yet explained. procedure ShortDelay(Interval: Word); assembler; { Interval = number of ticks Note: About 1193180 ticks/s } asm push ax push bx cmp Interval,0FFFFh { otherwise 0FFFFh will end in an infinite loop In the CRT.ASM file: 1.
Home EleBBS FAQ How to fix a Run Time Error 200 Run Time Error 200 (Divide by Zero) is usually caused by a bug Tp7p5fix If all the above fails, the other option is to run a TSR (Terminate and Stay Resident) utility that will provide a kluge to the division by zero issue by catching Some are to patch the CRT unit in your compiler (so you can produce programs free of the problem) and others are programs to patch executable programs that have the problem Such a solution will probably never exist.
DOS based programs that were compiled using these buggy versions of the CRT unit will generate the RTE200 error when started on a CPU that is faster then 200 Mhz (though The initialization part of the CRT unit has a calibration loop for the procedure DELAY. The disassembler displays file addresses and assigned logical addresses. They are neither the version of Turbo Pascal 7.0, nor the ones of versions 7.01.

Use: if your program is program.exe , enter the command tppatchprogram.exe Warning: This patch will cause delay to run too fast on computers that are significantly faster than Pentium Some (earlier?) compiler versions mysteriously seem to go free of this bug - Delphi doesn't have them, for instance, and Turbo Pascal 6 seems to work too.

Actually it is the same bug that on earlier processors caused Delay to be inaccurate, that now causes programs to fail with a runtime error if they use the CRT unit! The combination of removing the old delay-routine and using this replacement routine is what I do myself, if you include this routine in the crt unit, all you need to do Remove the Delay initialization code (lines 94 to 107, both inclusive). 3. http://opinfos.com/runtime-error/pascal-runtime-error.html This counter has an overflow on high speed cpu's, including Pentium II 266 Mhz and faster.
Warnings: the program patch is only suitable for programs that do not require precise timing the included TPL files were created based on the Run Time Library of Turbo Pascal 7.0 From the readme... I'm currently using the following procedures for generating a delay, the delay procedure is an exact replacement of the faulty Borland delay procedure.

Anyway, I've used this method on several programs, and it seems to work well. All programs compiled with Borland Pascal 7 that use the system unit Crt (almost all programs do that) abort with the error message "Runtime Error200" on all fast PCs, for example Risk using one of the other solutions below Index of other solutions bppatch Solution by German computer magazine c't contains description, program patch, source patch and copy of patched this content The best tool I have found to uncompress .EXE files is UNP.

response then the binary is now patched and in future those annoying runtime error 200 messages should be gone. Obviously that's only possible if you have the source code available. Thank you! [Top] [Home] [What'sNew] [ContactUs] [Referrals] [Feedback] [ProductsSummary] [DownLoads] [Orders] [Links] [Anti-Spyware] PatchCRT will only be able to patch .EXE files which have not been compressed by an EXE compressor, such as aPACK, Diet, LZEXE, PKLite, Petite, UPX, etc.
This file-size is about 30k. (See Download Instructions). Otherwise you can run the application in DOSBox which can artificially slow down the speed of the emulated DOS session. The patch program for executables has the same problem as all these patches: if the patched program uses the delay procedure, this will run at incorrect speed, thus if the program Lately there have been reports in usenet that Borland doesn't know about a 7.01 bug fix version, it's still called 7.0, so it may be better to ask for replacement disks
Technical Details: applies the same patches as in bp7patch (c't magazine), but uses the bugfixed Pascal version 7.01. It contains two things: a new delay procedure that prevents the overrun by using a 32 bit delay factor instead of only 16 bit. Note: we've seen a few EXE files with the 200 error, but which PatchCRT, up to ver 1.5, would not adjust.
