1.5 When I count the code I get 40 bytes, which makes me lean to 41 bytes for the answer. But if I look at the debug I count 56 bytes. If I just take the addressess in debug and do a subtraction (12F - 100) = 2F which is 47 bytes. Tricky.
1.9) I figure its i) AX and ii) also AX. But technically AL is part of AX, so does that make (3) a valid option?
