I have macro
macro must get register value and do if.
Num EQU eax
if Num = 10
mov eax,2
end if

How do this ?

Code:

Num equ eax
cmp Num, 10         ; equivalent to cmp eax, 10
jne @f
mov eax, 2

Preprocessor statements can only be used during preprocessing, not during runtime. You need to use real instructions to do the comparison during runtime.
