" ?? DJGPP's version of `system' doesn't care much about the extension, if you specify the extension explicitly. If you want it to guess the extension, then it will only look for a certain list of common executable extensions. So I don't quite understand the question. I also don't understand how does an extension affect the multi-programming issue. > And then another, so that they run nearly in a multitasking - system?? You cannot have several program running simultaneously in DJGPP, it doesn't support such multiprogramming. > Can I make it possible to run serveral programms at the same time, when > I use parts of the go32.exe sourcecode??? You can do anything you want, but you will have to write the multitasking code yourself, because it doesn't exist in go32 or anywhere else in DJGPP. And the DPMI spec makes it really hard to implement (because it prohibits changing a task from within a hardware interrupt handler). > P.S.

Note that this is from DJGPP v1.x which is no longer maintained.
