I have made a simple program by using the examples that come with fasm, but I cannot get this to work. The program should come up with a message box 32 times, but only runs once. It compiles fine, but I cannot seem to make it work.

Here is code:

Code:

include 'win32ax.inc'

.code

  start:
        invoke  MessageBox,HWND_DESKTOP,"Welcome to hell >:D",invoke GetCommandLine,MB_OK
        inc [loopcount]
        cmp [loopcount], 20h
        jne start
        invoke  ExitProcess,0

  loopcount db 01h

.end start

[/code]

.end start

section '' data readable writable
  loopcount db 01h

You might want to explain to him why you added the data section instead of just completing his code.

win32ax.inc

Code:

...
macro .data { section '.data' data readable writeable }

macro .code { section '.text' code readable executable } ;writes prohibited
