I installed FreeDos because I wanted to run a Pascal code using Turbo Pascal. When I run the code, it throws error 'Error 200: Division by zero.'. How can I solve this? -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;' uses crt; const { COM1: RS232 port address } RXTX = $3F8; { $2F8 if COM2: is used } ACK = 6; NAK = 21; ESC = 27; var dummy, checkSum : integer; key : char; protocol : integer; procedure InitComm; { Set baudrate to 9600, 8 bits, no parity, 1 stop bit } var i : integer; begin i := 1843200 div 9600 div 16; port[RXTX + 3] := $80; port[RXTX + 1] := hi(i); port[RXTX]:= lo(i); port[RXTX + 3] := 3; port[RXTX + 4] := $A; while odd(port[RXTX + 5]) do begin dummy := port[RXTX]; delay(10); end; end; { InitComm } procedure Tx(data : integer); { Transmit a character on serial channel } begin while port[RXTX + 5] and $20 = 0 do; port[RXTX] := data and $FF; end; { Tx } function RxWait : integer; { Waits for a character from serial channel } begin while not odd(port[RXTX + 5]) do; RxWait := port[RXTX]; end; { RxWait } procedure Tx2(data : integer); { Transmit a char on serial channel + Calculate check sum } begin Tx(data); checkSum := (checkSum + data) and $FF; end; { Tx2 } procedure TxCommand(c1, c2 : char; sendCheckSum : boolean); { Transmit command (no data) on serial channel } begin Tx(ESC); checkSum := 0; Tx2(ord(c1)); Tx2(ord(c2)); if sendCheckSum then begin Tx2(checkSum); dummy := RxWait; end; end; { TxCommand } function
MSS03USA 2006South Africa 2008 Last updated: July 18th, 1999(Uploaded May 17th, 1998) Runtime Error 200 running a Pascal program on fast systems (PII 266+) Contents of this document General information Programmers information Programmers Option 1: Enhancing the Delay-routine Programmers Option 2: Removing the Delay-routine Optional replacement delayloop Users Patch-program General information The Runtime Error 200 (Division by zero) bug is not part of the Pentium Errors. It's a mistake Borland made. The initialization part of the CRT unit has a calibration loop for the procedure DELAY. The resulting value of a counter depends on the speed of the cpu. This counter has an overflow on high speed cpu's, including http://stackoverflow.com/questions/21647352/how-to-resolve-error-200-division-by-zero Pentium II 266 Mhz and faster. 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! 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. Please http://mtech.dk/thomsen/program/pasbug.php 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. Keep backups of the appropriate files! (and then some...) Programmers As a programmer you have several different options. First of all you can disable the delay-routine completely. If you need a delay routine you can use the one found in this document, you can create your own, or you can find another one somewhere on the web. Another solution is to change the Delay-routine so it will work on todays fast systems. This solution found in this document should push the problem about 10 years into the future if we assume that Moores Law is correct. If you're having Borland Pascal, you also have the sources of the runtime library. Just make the following changes and recompile the complete runtime library. A MAKEFILE is included with the sources. If you have Turbo Pascal only, it's a bit more complicated. You'll need the sources of unit CRT. At least the files CRT.PAS, CRT.ASM and SE.ASM. They are the same in 7.0 and 7.01.

Wersja podstawowa -nie zawiera wszystkich poleceń Pascala. Służy do nauki podstaw FAQ - Najczęściej zadawane pytaniaDlaczego Turbo Pascal mi nie działa? Turbo Pascal został opracowany na stare komputery. Dobrze radził sobie w Windows 98, czasami w XP. Aby pisać w Pascalu na najnowszych komputerach error 200 division można skorzystać z Virtual PC lub lepiej zainstalować wersję obiektową -czyli Delphi. W sieci dostępne jest darmowe środowisko Delphi 7 PersonalDlaczego mam 'RunTime Error 200 Division by 0'? Jeśli posiadasz Turbo Pascala bez Patch'a i użyjesz modułu Crt wystąpi błąd Error 200: Division by 0. Rozwiązaniem jest zainstalować Patch. Pobierz Patch z działu DownloadCo zrobić, żeby działała grafika? Mam BGI Graphics Error Aby zadziałała grafika, gdy używasz polecenia InitGraph(Gm, Gd, ''), musisz podać ścieżkę, w której znajduje się sterownik do grafiki, plik: Egavga.bgi. Domyślnie, pliki te są w katalogu BGI. Polecenie może wyglądać następująco: InitGraph(Gm, Gd, '../BGI'). Jeśli chcesz by program szukał pliku Egavga.bgi w katalogu programu, musisz skopiować plik z katalogu BGI do katalogu BIN -lub tego, który ustawiłeś w Options->Directories. Wtedy możesz pisać InitGraph(Gm, Gd, '')Jak wczytać kod klawisza, nie zatrzymując programu? Zadeklaruj moduł Crt. Potem zadeklaruj zmienną 'ch:char'. Następnie napisz: 'if keypressed then ch := ReadKey'. Teraz w zmiennej ch znajdziesz wartość wciśniętego klawisza, bez zatrzymywania programu.Jak skompilować program, żeby otrzymać plik .exe?

are no longer functioning. Instead they reply with an error message like 'Runtime Error 200: Divide by zero'. In this case, the program is a Pascal program using the CRT unit. At startup of the program, the Crt.Delay loop is executed. The loop counter, divided by 55 is on these machines larger than what fits in a 16-bit register. So the 'divide by zero' error message isn't really correct. There are a couple of patches available for this problem. Some patches are RT (runtime): they fix the actual program. Other patches actually alter the source code of the CRT. But this is only useful if you compile Pascal programs yourself. Already built programs won't be changed. Runtime patch I have one patch here that should work with any Pascal programs compiled with TP/BP 6.0/7.00/7.01. I have finally been able to check this patch (unfortunately not on my very own PC, which is still too old, I'm afraid...) and guess what... IT WORKS! The patch has background information in German (TPPATCH.DOC) and English (TPPATCH.ENG). The patch can be executed by starting TPPATCH.EXE. If you want to patch from inside Windows NT, run NT.BAT instead. Get TPPATCH.ZIP. BP7 CRT source patches (compiletime) I have two of those patches here. The patches have been tested, but only the second one seems to work for protected mode programs. The patches work with versions 7.00/7.01 only. See readme.txt in the files for instructions.
