Converting DOS based Pascal to Windows

I have a program which was written years ago in DOS Turbo Pascal. It is on a Windows 95 machine but its getting old and sluggish. Can anyone advise how this can be converted to a more up to date version of Windows e.g. XP and what I would need to achieve this.

Many thanks

Turbo Pascal 5.5 (available for free from borland.com) can compile executables that run on WinXP machines. Note that there are features that do NOT work on faster machines. I don't know the final status of BGI, for example, but for a while fast clock speeds made BGI-based programs lose their minds. If your program interacts directly with the hardware you may well have problems, too.

Now if the question is how do I move an old, DOS looking program to the GUI age, I would look long and hard at a current version of Delphi. You are in for more rewriting rather than porting in this case and you may still have problems directly moving hardware-centric code to Win32.

Hope this helps, -bcl

It work on Windows Xp. If you compile the source code and received 'error division by zero'
it means something wrong with BGI. You can patch your code.
