LOOPZ Loop While Zero Flags: not altered
LOOPZ short-label
Logic: CX . CX - 1
If CX <> 0 and ZF = 1
JMP short-label
Used after a CMP or SUB, LOOPZ decrements CX by 1, then transfers
control to short-label if the first operand of the CMP or SUB is equal
to the second operand. Short-label must be within -128 to +127 bytes
of the next instruction.
