here I'm again with a MASM question

following problem:


mov ebp, 012345678h ;//some value

lea ESI,
mov dword ptr , ebp

;// above 2 lines should patch the instruction
;// mov eax, 66666666h to mov eax, 12345678h

call BlaBla ;// after this call there should be EAX=12345678h

invoke ExitProcess,0

BlaBla Proc

nop
xyz: mov eax, 066666666h
nop
ret

BlaBla Endp



--> gives a error message: Undefined symbol xyz


(this is self modifing code. make shure that .CODE section is writeable)

Anyone with a solution for this? :confused:

CRYO

Simple solution:

BlaBla Proc 



nop

xyz[color=red][b]::[/b][/color] mov eax, 066666666h

nop

ret



BlaBla Endp

Labels inside PROCs default to private - the double colon makes it global - be careful to not use this frivalously. :)
