 Actually, I agree; I posted the code as I expanded it from Bob
Ammerman's suggestion. I guess it's a big- vs. little-endian thing.
I may end up reversing it, but it works. I used the same structure to
create a bit doubler, by the way. Not much longer than the lookup table
method, and there's some advantage in readability, to using the same
algorithm for both! I might make a tripler, and compare size/time between
the 6X code and (2X * 3X)... Gut feeling is that 6X is shorter, faster.
