hmmmm, karlss0n, thanks for the response but im still a bit confused....
I want to do this exactly;

000001E4 + 200 = 00000???
the "correct" answer is 000002C0, What I need to know how does this '000002C0' comes about. Where does that 'C" come from? lol, I'm sorry, I know this is probally a big stupid question and all.
