when you afterincrement something, the operation size or something is then
added to a0 after the instruction is completed
 ie: move (a0)+,d0
In this case 4 would be added to a0 afterwards...I know this because I read
it...BUT how do I know what the insruction size is...Why is it 4

Also what is unsigned/signed integers?  You used different branch instructions
depending on what kind of integer, right?  Or something like that...I'm just
typing off the top of my head rightn now...THANKS
