BCD to ASCII conversion

The HEX equivalent of ASCII '0'(zero) is 30H.Thus to convert a packed BCD to ASCII we need to add 30H to the unpacked BCD

Packed BCD
34H
0011 0100
------------------------
Unpacked BCD
03H & 04H
0000 0011 0000 0100
---------------------------
ASCII
33H & 34 H
0011 0011 0011 0100

reply to amarnath
BCD code contains digits<10
so A,B,C,D,E,F these values not occur in BCD
BCD equivalent of A is:
0001 0000
i think now you have some good idea
