Show your whole code please. We can't guess what you have done with only partial code.

In order to use ExitProcess you need its offset, whether imported static or dynamically from kernel32.dll

Anyway a quick solution:
replace
Code:
include 'win32a.inc'
    

by
Code:
include 'win32ax.inc'
    

and
Code:
push 0 
call ExitProcess
    

by
Code:
invoke ExitProcess,0

You could try:
Code:
format PE GUI 4.0 
include 'win32a.inc' 
entry start 


section '.data' data readable writeable 
;        ........... 

section '.code' code readable executable
         start:
;        ........... 
         push 0 
         call [ExitProcess]


section '.idata' import data readable writeable

library kernel,'KERNEL32.DLL'
import kernel, ExitProcess, 'ExitProcess' 
    

Or,
You could do as ass0 recommended:
use include "win32ax.inc", which makes things easier.
Code:
format PE GUI 4.0
include 'win32ax.inc'
entry start


.data
;        ...........

.code
         start:
;        ...........
         invoke ExitProcess,0
.end start

;There are no needs to import DLLs when using "include 'Win32ax.inc'"

i personally prefer the 'TerminateProcess' API for a fast dirty process kill.

Despite race condition in Gold/SP1/2 implementations?

Some things easier, some things harder. What if you/he need/s some function outside of set declared in «API\*.INC»?

I fail to see how that applies, the only case where i could see something like that applying is if someone were to use the API to terminate a system process. But even then, i don't see any sources linking the race condition to this particular API. The only possible problem i have seen with this is that it doesn't give the process a chance to execute cleanup code. Which when i normally use it i want a hard shutdown of the intended process, not a proper cleanup, usually because the process has frozen or is one of those annoying programs that won't let you close it.
