I hope this is in the correct place. There is no search for me to tell if this question
has been asked.
We used to use "INT" in MASM32 coding and then it went the Windows APIs.
Can you tell me if the "INT"s used in MASM32 are similair or the same in "FASM"?
Are they documented somewhere on this site?
I'm still learning about this site.
My previous question was about a flat assembler and I think it has been answered.
Thanks for any direction.

INTs are for the OS to interpret not the assembler. You can still use all the INTs in fasm that you used in MASM. But be aware that Win32 programming uses a DLL paradigm and does not support INT for user mode programs. That is why INTs are not used with Windows programming. Not because the assembler does/doesn't support it. You can still put in INTs if you like but in Windows OS you will likely get a GP fault.

However you are posting in the Linux forum so does that mean you are writing Linux program? Linux uses INT 0x80 for the API. See the fasm examples of Linux programming in the download.

Thanks for the reply.
Yes I am writing in Linux(FASM).
I'll check out the examples.
