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.

                      instruction.
