          Jump Condition:      Jump if CF = 1

    target of the jump must be within -128 to +127 bytes of the next
    instruction.

       Note:          JB (Jump if Below), JC, and JNAE (Jump if Not Above
                      or Equal) are all synonyms for the same instruction.

                      Use JNC, Jump if No Carry, to jump if the carry flag
                      is clear.
