So, it’s super slick to use Linux system calls in assembly language programs, and now I am thinking about extending my re-implementation of an Apple II style “monitor” program as a means of a operating system independent machine code type-in. So, does Windows have an equivalent to Linux system calls such that I can use it to create ultra-compact Windows programs? Unfortunately, no, just as I have been suspecting. No, no, you have to link against some Windows library, and that Windows library will provide the necessary routines to make the actual system calls by number, which differ by the version of Windows and are not held constant in any way.
