Pascal Runtime Error 200 Fix


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 It is known as the CRT unit issue and can be fixed by applying a patch to the effected application. Back to homepage. The patches have been tested, but only the second one seems to work for protected mode programs. http://kiloubox.com/runtime-error/pascal-runtime-error-123.html

Turbo Pascal had a timing bug that would cause its complied programs to crash when they were operating on machines running at 200Mhz or faster. 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 However, by running "ctbppat [filename.ext] /brute", one can force the program to search for the incorrect code but WITHOUT further analysis (which prevents error checking and will then allow the faulty tpbug.zip new TPL files not available for download here because of potential copyright problems File contains exactly the same files CRT.ASM, CRT.PAS and CRT.TPU (included in TURBO.TPL) as BPPATCH.ZIP. http://www.pcmicro.com/elebbs/faq/rte200.html

Dos Runtime Error 200

Home EleBBS FAQ How to fix a Run Time Error 200 Run Time Error 200 (Divide by Zero) is usually caused by a bug in So run the UNP program to decompress the binary. This file-size is about 30k. (See Download Instructions).

Replace the 16-bit delaycounter DelayCnt DW ? CRT,CRT.OBJ,CRT.LST compile TPC -$d-,l- CRT and insert the result to TURBO.TPL TPUMOVER TURBO.TPL -CRT TPUMOVER TURBO.TPL +CRT and now, it will even work on your neighbour's Pentium II. It's a mistake Borland made. additional feature: disables all other interrupts during delay initialization to make initialization more reliable.

The preferred solution is to use an updated version of CRT.ASM, or to contact the software developer, and request that an updated CRT.ASM be used to re-build the app/utility. Tp7p5fix 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. Anyway, I've used this method on several programs, and it seems to work well. http://mtech.dk/thomsen/program/pasbug.php This has worked for about 80% of the compressed .EXE files I have encountered.

That's a nasty trick, I don't like it, but it seems to work. MKDIR C:\TPATCH Unzip both downloaded packages into the temporary directory. Fixed.

Once you have sucessfully uncompressed a compressed .EXE file, you should then be able to run PatchCRT on it to remove the RTE200 bug. Other programs should work fine with this. Dos Runtime Error 200 Users Before you do anything yourself, you should try to contact the programmer, so he can fix the problem using the steps listed above. Dosbox Runtime Error 200 Create a temporary directory.

Fixes for "RuntimeError200" bug of Borland Pascal 7 on fast PCs Note: You are reading the download page. Additional feature: tries to make a program behave nice during delays if it runs in a multitasking environment. The more common solution is to patch the .EXE file to disable the bug. this contact form If it works, you can probably re-compress the updated file, or just use the de-compressed version.

Otherwise you can run the application in DOSBox which can artificially slow down the speed of the emulated DOS session.

The first way is to use a patch in order to get the program to work, but this is risky. Borland Pascal Runtime Error 200 problem There is a problem in the CRT unit of Borland Pascal 7 and Turbo Pascal (for DOS) which manifests itself as... Obviously that's only possible if you have the source code available. Repeat steps one and two each time you access DOS as the TSR will not be active unless you load it each time.

In the patched versions the delay procedure will use a 32 bit counter similar as in newdelay but without the nice idle behaviour. If you don't like it, disable it in the source. 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 navigate here Ceterum censeo Microsoft esse delendam.

Of course it is possible that it also can patch those files. Thank you!

Technical details: A patched program will test if the computer is too fast.

The best TSR I have found to do this is TP7p5fix. Use: In your program sources include this unit first, crt second, then all other units and then recompile your programs. In the CRT.ASM file: 1. The bug was specifically in the CRT.ASM unit included with these compilers.

Steps: Run the TP75.EXE and allow loading into TSR memory. BP7 CRT source patches (compiletime) I have two of those patches here. Runtime Error 200 Causes The Runtime Error 200 problem is generated in the initialization routine’s internal workings. I'd suggest keeping PatchCRT.exe in your path, so that you can run it from any directory simply by typing it followed by the name of the .EXE to be patched.

Get BP7PATC2.ZIP. Please note: I take no responsibility for the potential damage people may do to their RTL's, working programs or vital data while using the instructions in this document. PKUNZIP TurboPascal-Unpack.zip C:\TPATCH PKUNZIP crtfix16.zip C:\TPATCH In our example we are going to patch defacto.exe which is the binary from an early Defacto magazine that suffers from this bug. Keep backups of the appropriate files! (and then some...) Programmers As a programmer you have several different options.

Running in pure DOS mode with SmartDrive (if possible) will also increase analysation speed.If ctbppat finds an executable made with Borland Pascal 7.0, it will examine the file further to determine response then the binary is now patched and in future those annoying runtime error 200 messages should be gone. The nice thing about UNP is it runs well under Windows.
