Note that "repeated addition" may be a misleading way to describe how to do multiplication on a 6502/etc: it would be silly to to M or N additions to multiply MxN. Instead, the number of additions would typically be the number of *bits* turned on in either M or N, and there would be some bit shifting. --Dave Lyons, Apple Computer, Inc. | DAL Systems AppleLink--Apple Edition: DAVE.LYONS | P.O.
