I may be just a little too much issolated in my windows world, but I am scratching my head here wondering (and I have searched the fourm - found some great threads that I have enjoyed, but have not found the answer to this question...)

Ok, to the point: What is the difference between FASM for DOS and FASM for windows? Is it merly a 16 bit memory model -vs- a 32bit memory model?

What are the implications to code being ported from DOS FASM to Windows FASM?

I appreciate your help. Brad

Basically, all versions of fasm will generate same output from the same source. So it is no difference which one you use to compile your programs. fasm for win32 can compile dos programs, as well as linux ones.
Only difference between different fasm versions is and OS that they can run on.

did you mean differences between assembly coding in DOS and Windows?

Yeah - I might have, not understanding really what I am asking.

So here is the other question - can I compile programs that call windows routines (via DLL) using the DOS version of FASM, or do I need to use the windows version.

I guess then I am asking - is the output of DOS FASM restricted to being console, or by calling windows routines can I generate windows GUI executables, or must the windows version of FASM be used for that?

Thanks

you can compile it using any version of FASM. Output of all versions FASMs is same. Output of FASM depends ONLY on contents of source fil you are compiling (and including of course)

altho you'll need the Win32 version to get the win32 macros.
