    I can tell you that to use C functions from a library, it is necessary to
    initialize the C environment. The C compiler builds the executable in such a
    manner that a call to an initialization routine called something like __cmain,
    but I can't remember exactly, since it has been a long time since I did this.
    You will need to make the appropriate call before you can use the C libraries.
    You will need to make sure that the stack is set up in such a manner as expected
    by the libraries that you are calling.

    I suggest that you make a "hello world" program in c then get the compiler to
    output the assembly language source. You need to then try and get your
    assembler to compile it and see if you can run it.

    I hope in future to have a MASM 6 equivalent for Linux.

    Regards,

    Mark.
