Consider this integer Chris, 7863 = 0111-1000-0110-0011 -- BCD 7863 = 10110111 -- BYTE 7863 = 1111010110111 -- Dword / word in BCD the largest decimal that can be displayed by any four digits is 9 and the four bits are the binary equivalent of 1 thru 9. I'll be happy to see how it will all work out. Will it be fast and efficient?.
