INC              Increment                           Flags: O D I T S Z A P C
                                                            *       * * * *
INC destination

          Logic:    destination . destination + 1

    INC adds 1 to the destination. The destination, which may be either a
    byte or a word, is considered an unsigned binary number.

       Note:          This instruction does not set the carry flag.  If
                      you need to add 1 to a multi-word number, it is
                      better to use the ADD and ADC instructions instead.
