Hi,Dear friends..

Ask a question，I have just learning "fasm"。Before use "MASM"。MASM Provided in the "RtlZeroMemory" function。 fasm Whether have similar Macro。I write a

mov edi,@stWndClass
mov ecx, sizeof.WNDCLASSEX
xor eax,eax
rep stosd

However, lack of access to local Variables address。

Is there a similar MACRO?

bug. you must "mov ecx, sizeof.WNDCLASSEX/4".

Local variables are addresses relative to EBP (eg. "mov eax, [ebp + 8]"), best way to get their address is to use LEA instruction:

Code:

lea edi, [local_variable]
