Turbo Pascal 7.0 Crt Patch
Turbo Pascal 7.0 Crt Patch >>> https://fancli.com/2t0Cax
-Turbo Pascal 7.0, Free DOS 1.1, Virtual Box 4.3.6, Windows XP Service Pack 3 Host machine-This error is unfortunately caused by fast Pentium CPUs and I found a patch on the internet that will resolve the error. (www.filewatcher.com/m/bp7patch.zip.62550-0.html) Now the other problem is, when i was tracing the code, it hangs at 'RxWait procedure when trying to execute while not odd(port[RXTX + 5]) do;'
Old question I know, but there is another way to write Turbo Pascal code without incurring the wrath of the infamous RTE 200 bug. FreePascal (www.freepascal.org) is fully TP7 compatible and runs under a number of OSes including DOS, Windows and Linux.
There is a problem in the CRT unit of Borland Pascal 7 and Turbo Pascal (for DOS) which manifests itself as... Runtime Error 200 - Divide by 0 ...immediately upon startup of a program created with these compilers when run on a Pentium-class computer faster than about 180mhz.Borland (now Inprise) has no officially-supported fix for this but several unofficial fixes have appeared on various Pascal programming forums and newsgroups. 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 (in which case you do not need the source code or the means to re-build the problem program).A patcher for existing problem programs written by Andreas Bauer appears to work.I have used it on a 233 mhz Pentium II and have heard of others using it on up to 400mhz machines. The ZIP file contains documentation in English (shown below) and German, and the patch seems to work as described.The patch used to be on Klaus Hartnegg's pages at... -freiburg.de/~klaus/pascal/runerr200/ ...but as is often the way with sites at universities, Klaus' directories are gone now.I have placed the file here. tppatch.zip (9,623 bytes)Here is the English version of the documentation... TPPATCH does fix a bug appearing in all programs that have been written using Turbo Pascal when such a program is run on a Pentium Pro 200MHz or a faster computer.
To patch software without having the source of it, you can apply better methods, for example replacing Delay() if you have the runtime sources, and a unit has been posted in some newsgroups that will circumvent this with various low-level tricks.
With this patch Delay() does run correctly on all slower machines, likewise on a Pentium Pro with 200MHz. But if there are even faster processors one day, Delay() will wait a bit to short on them. But the programs patched with TPPATCH will never hang again because of the bug.
The program (TPPATCH.EXE) examines the file it is commanded to patch exactly, so no exe file will be "patched to death". The position of the variables are scanned automatically, so the patch should work with *all* versions of TP7/BP7. But I haven't tested it with TP6. Of course it is possible that it also can patch those files.
I'm not responsible for any action that is performed by TPPATCH, nor do I give any waranty about the function of it. Before you go and patch foreign software you should take a look into a LICENSE.DOC file or anything similar.
