LOOPE            Loop While Equal                    Flags: not altered

LOOPE short-label

          Logic:    CX . CX - 1
                    If CX <> 0 and ZF = 1
                        JMP short-label

    Used after a CMP or SUB, LOOPE 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.
