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?.
