how is 8765h INC 1 negative? I know its negative because the answer says sign flag=1 but how?
You can tell whether a hexadecimal integer is positive or negative by inspecting its most significant (highest) digit. If the digit is ≥ 8, the number is negative; if the digit is ≤ 7, the number is positive. For example, hexadecimal 8A20 is negative and 7FD9 is positive
Wouldn't that only be true on 16 bit systems?
