I wanted to experiment and test out whether the register AL will have a bit limit of

Answer 1

As I understand it, DumpRegs gives you the output of EAX. When I convert your answer to HEX, I get 5209284F, the 4F being in the AL. 4F HEX is 79 Decimal, which is 335 - 256. The AL register only holds 8 bits, so 256 is the maximum unsigned integer it can hold.

Clear EAX before you begin and the results may make more sense.
