    Resolved [RESOLVED] [MASM] Clarification about Symbolic Constants

    Theres an ambiguous part in a book I'm reading about MASM, I won't quote it here but tell me how the following code behaves...


    Code:
    NUMBER = 20 ;does this really mean 5?
mov eax, NUMBER 
NUMBER = 5
mov ebx, NUMBER 
add eax, ebx
    I inferred from the book that the very last instance of ...

    Code:
    NUMBER = ??
    ... propagates through the whole file rendering all of the other instances useless. Is this right?

    If this is the case then eax now contains 10 (5+5). But my own mind makes me think that it would actually contain 25.

    I know how things like this behave in other languages and they way the book says it sounds weird.

    Can anyone shed any light?

    (I would try it but I haven't got MASM on this machine)
