Hi everybody, I'm having problems turning this instruction to fasm :

mov eax, fs:[30h] <- which is masm.

So, if someone's got an idea, please help me.
Many thanks.

But This part of my code for the program not to be debug-able make it crash on win2000 stations, on XP it works fine
Code:
     push    00h
 mov eax, [fs:30h]
       movzx   eax, byte [eax+2h]
  or      al, al

  jz      ok
  jmp     debug

   debug:      invoke  ExitProcess,0
    


if the program is being debugged it closes and if not, it runs normally.
Help me please

   test    ecx, ecx
    js      _9x
 movzx   ecx, byte[ecx+2]
    jecxz   @F
;;;;blah blah
_9x:
     mov     ecx, [fs:20h]
   jecxz   @F
;;;;;blah blah
