I have never tried doing this under Windows 2000 or XP, but it has always worked for me on Win98 and NT4. Unless 2k made some modifications of the NT kernel in this area, I don't see why it shouldn't work.

Maybe I was thinking of trying to execute code out of the data section.

Well, if it works, it works.

And here is another example:

Code:

format PE GUI 4.0
include '%fasminc%\win32a.inc'
start:
call _smc
push 0
push ttl
spot:
push msg
endsp:
push 0
invoke MessageBox
invoke ExitProcess,0

_smc:
push esi edi
mov esi,_src
mov edi,spot
mov ecx,endsp-spot
rep movsb
pop edi esi
ret
_src: push msg2
msg db "I'm the first msg!",0
ttl db "SMC",0
msg2 db "I'm changed! LOL!",0

data import
library user32,'user32.dll',\
kernel32,'kernel32.dll'
include '%fasminc%\apia\user32.inc'
include '%fasminc%\apia\kernel32.inc'
end data

Works ok with WinXP and FASM 1.64.
