JLE              Jump If Less or Equal               Flags: not altered

JLE short-label

          Jump Condition:      Jump if SF <> OF or ZF = 1

    Used after a CMP or SUB instruction, JLE transfers control to short-
    label if the first operand is less than or equal to the second . (Both
    operands are treated as signed numbers.)  The target of the jump must
    be within -128 to +127 bytes of the next instruction.

       Notes:         JNG, Jump if Not Greater, is the same instruction as
                      JLE.

                      JBE, Jump if Below or Equal, should be used when
                      comparing unsigned numbers.

                      JLE, Jump if Less or Equal, should be used when
                      comparing signed numbers.
