Does anyone out there know how to do this:  I want to compute   s = a0 * b0 +
a1 * b1 + ... + an * bn where n is to be determined at run time, and could be
as large as 300,  and the ai, bi are unsigned byte quantities, and s is to be
scaled to an unsigned byte quantity. Also, I don't want to do it in floating
point.  It seems this should be pretty straight-forward, but I keep getting 
myself confused.  I think Forth needs a word to detect when CARRY is set.
Anyway, any input would be appreciated.
