JL               Jump If Less                        Flags: not altered

JL short-label

          Jump Condition:  Jump if SF <> OF

    Used after a CMP or SUB instruction, JL transfers control to short-
    label if the first operand is less than 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:         JNGE, Jump if Not Greater or Equal, is the same
                      instruction as JL.

                      JB, Jump if Below, should be used when comparing
                      unsigned numbers.

                      JL, Jump if Less, should be used when comparing
                      signed numbers.
