The HI-TECH C library 16x16 multiplication will produce an error anytime there is a carry out of btemp while the value in btemp+1 equals $FF<BR>

Looks like I made a mistake; on 16 bits it just generates an overflow. It would cause an error if the code is expanded to 24 bits as the resultant carry is lost in loading ++btemp+1 into w.<BR>
