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 dosbox runtime error 200 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 da

old game and it was written in Turbo Pascal, chances are, on any machine over 200MHz, you will get an Error 200 (Divide by zero error). This program corrects the problem by patching your executable. From the readme... 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 error occurs due to incorrect initialisation of the DELAY counter.ctbppat is also a universal EXE scanner, monitor, http://stackoverflow.com/questions/21647352/how-to-resolve-error-200-division-by-zero and patcher. It supports the usual EXE formats -- MZ for DOS; NE for OS/2, DPMI, and Windows 3.11; and PE for 32-bit environments -- and can detect the language with which the file was created. Running "bppatch *.* /s [/p]" will list all file formats in the current directory.If you use the switches /NE, /MZ, or /PE, ctbppat will be restricted to the respective EXE format. This will increase the speed with which it can analyse files. Running in pure DOS http://www.vogons.org/viewtopic.php?t=93 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 if it uses an original or changed CRT unit, whether this unit is already patched, and whether the DELAY function is called at all. (If it is not, patching is unnecessary.)Depending on the result of this examination, ctbppat may offer to patch the file. If the DELAY function is used, it can be fixed by using a different delay routine that should function properly up to ~4GHz.To do this, the BREAK routine in the CRT unit is shortened and the delay code patched into the free space.If DELAY is not used, the divisor is simply increased to 65535. This will prevent DELAY from operating; however, this will ensure that the program is able to run (theorhetically) on a 300GHz CPU.If the CRT unit has been changed, but contains the same incorrect initialisation, ctbppat will modify the faulty divisor (255 => 1).ctbppat only analyses original CRT units -- routines with similar incorrect code in Tool Boxes remain unchanged. 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 code to be changed). ctbppat will then allow you to patch the code with the new divisor (the default is 255, but by using the "/BRUTE=XXXX" switch, where XXXX

It's a mistake Borland made. The initialization part of the CRT unit has a calibration loop for the procedure DELAY. The resulting value error 200 of a counter depends on the speed of the cpu. This counter has an overflow on high speed cpu's, including 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 runtime error 200 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 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 sour
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.
