Hi Robert,

In summary, taking the examples I posted for 24-bit composite variables, and
assuming 16,777,216 increment/decrement iterations, your speed improvement
savings will be:


     24-bit Increment: ~ 14% faster than your snippet
     24-bit Decrement: ~ 25% faster than your snippet


It's interesting to see that the decrement speed improvement savings is
significantly more than the increment. My hunch was that it would be the
same.

Moreover, Scott's 24-bit decrement is also very quick:
     ~ 25% faster than your snippet
    (same number of clock cycles as the snippet I posted)



Now what are you going to do with all those extra clock cycles? :)


Best regards,

Ken Pergola

P.S. I indirectly obtained these figures from the MPSIM simulator in MPLAB
IDE v6.62.
