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 turbo pascal error 146 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 whil

Runtime Error 202 Turbo Pascal

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 http://stackoverflow.com/questions/21647352/how-to-resolve-error-200-division-by-zero 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 CRT unit! Some (earlier?) compiler versions mysteriously http://mtech.dk/thomsen/program/pasbug.php 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 sources of the runtime library. Just make the following changes and recompile the complete runtime library.

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. http://s416217492.onlinehome.us/error200.html 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 https://sites.google.com/site/chanyfic/pascal need the source code or the means to re-build the problem program). A patcher for existing problem programs written by AndreasBauer appears to work. I have used it on a 233 mhz Pentium II and have heard of turbo pascal 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... http://www.brain.uni-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 200 trong turbo 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. This bug causes a runtime error 200 when the startup code of Delay() is executed. The bug appears when a DIV instruction is executed and the result does not fit into the destination register. With this bugfix you can patch all files that have been compiled with Turbo Pascal, for example Crosspoint. This procedure does also work with applications compiled for the protected mode. 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.

había bastante gente consultándolo.Voy a empezar la sección de Pascal hablando del RUNTIME ERROR 200 del Turbo Pascal y del Borland Pascal. Seguro que alguna vez te bajaste algún programa que funciona bajo DOS, y funcionaba bien en tu ordenador viejo, pero al probarlo en un ordenador más rápido ponía algo así como RUNTIME ERROR 200 AT XXXX:YYYY. Esto se debe a que cuando la gente de Borland programó el Turbo/Borland Pascal, los ordenadores no eran tan rápidos como los de ahora. Me explico: En pascal se pueden usar 'units', que viene a ser algo así como los #include de c/c++. Una de esas units, la CRT, que es una de las más usadas, tiene una función llamada DELAY, que produce una parada de X milisegundos al llamarla de esta manera: DELAY (X); ¿Que cómo hace para saber cuanto tiempo tiene que detener la ejecución? En el código de inicialización de la unit, que se ejecuta al principio de cada programa que la use (por eso el programa no llega ni a arrancar), ejecuta un bucle de 55ms en el que se incrementa una variable LONGINT. Al acabar, se hace una división entre 55 para saber cuántas veces tiene que incrementar la variable hasta que pase 1ms, y el resultado lo guarda en una variable tipo WORD (0-65535). En un ordenador lento no hay problema, pero cuando usamos uno de más de 200MHz (aproximadamente), la variable LONGINT aumenta tanto que al hacer la división, el resultado no cabe en la variable WORD. Ahora es cuando el ordenador 'razona': al no caber el resultado, eso quiere decir que es un valor infinito, y la única manera de que haya dado infinito una división es que lo haya dividido entre cero, y saca por pantalla: RUNTIME ERROR 200 (división entre cero, en el manual de Turbo/Borland Pascal). Para corregir ese error, se pueden hacer varias cosas: - Si no tienes el código fuente del progr
