    First of all you have to find an ancient 16-bit compiler. I think that the old Borland Turbo C++ suites now are available for free so go ahead and search.

    Then you have to find an OS that is able to run a com-file (and also the compiler). Whithout knowing for sure I would guess that it means you have to go back to something like Windows Millenium edition or earlier. If the executable is well behaved (don't have wild accesses to hardware) it might also run in some of the more recent NT based 32 bit versions of Windows but I don't know if and if so when the support for .com ended.
    Debugging is twice as hard as writing the code in the first place.
    Therefore, if you write the code as cleverly as possible, you are, by
    definition, not smart enough to debug it.

    The short answer is no.

    Why?
    All advice is offered in good faith only. All my code is tested (unless stated explicitly otherwise) with the latest version of Microsoft Visual Studio (using the supported features of the latest standard) and is offered as examples only - not as production quality. I cannot offer advice regarding any other c/c++ compiler/IDE or incompatibilities with VS.

    You were just told how to create. You need a compiler that can target MS DOS. The most known are Borland C++ 3.x, MS Visual C++ 1.x, Watcom C++ something, I don't remember, 8 or 9, or maybe 10. You can try Open Watcom, maybe they still support DOS just for fun.
    Best regards,
    Igor
