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