Nir ,

To convert byte (from 00h till 3Bh) in memory to a Decimal Digits you have to use following code fragment

MOV B,#10
DIV AB ;Quotient is in Acc (tens)
ADD A,#30H
MOV R3,A
MOV A,B ;Remainder is in B (ones)
ADD A,#30H
XCH A,R3

That's all.

By the way, the BCD is abbreviation of Binary Coded Decimal and so byte contains decimal digit in each nibble of byte (0,1,..9).
