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 ReadNumber(n : integer) : real; { Read n bytes from serial cha

Topic locked 3 posts • Page 1 of 1 Fix "Error 200" (Divide by zero) - by Snover and Stiletto, with thanks to edelbeb by Snover » 2002-7-26 @ 00:40 If you're trying to play an 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 © http://stackoverflow.com/questions/21647352/how-to-resolve-error-200-division-by-zero 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, and patcher. It supports the usual EXE formats -- MZ for DOS; NE for OS/2, DPMI, and Windows 3.11; and PE http://www.vogons.org/viewtopic.php?t=93 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 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
encounter this Runtime Error. Runtime Error 200 Symptoms Like any other Runtime Error, Runtime Error 200 lets itself be well known via a pop up alert. This “bug” seems to pop up in DOS http://wiki-errors.com/runtime-error-200-%E2%80%93-the-pascal-error/ based programs that were faster than 200MHz and could make an already slow machine even slower and/or inoperable. Runtime Error 200 Causes The Runtime Error 200 problem is generated in the initialization routine’s internal workings. What http://www.oocities.org/siliconvalley/network/6493/tppatch.html happens is a code will actually measures the “running time” of what is called a busy wait loop. While doing so it calculates how many times a call must be made for a delay in the correct error 200 amount. When the computer moves too fast and the loop takes zero ticks and the calculations come up as “Division by Zero’ or Runtime Error 200. Solving Runtime Error 200 There are two ways in which you can go about solving Runtime Error 200 problems. The first way is to use a patch in order to get the program to work, but this is risky. If you do this be sure you are runtime error 200 using a reputable website in order to get the patch as some patches are really nothing more than viruses in disguise. Another solution is to run a TSR, or Terminate and Stay Resident, utility. Steps: Run the TP75.EXE and allow loading into TSR memory. Run your DOS program and avoid the error message. Repeat steps one and two each time you access DOS as the TSR will not be active unless you load it each time.

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.
