Yes, Onkar, I agree with you that there is some confusion. The program I reported is for BCD addition. The value in Hex format of course represented a Binary Coded Decimal value. Or DAA is not required.
I have found this DAA bug existing in many software simulator/Emulator programms. Perhaps DAA is not that important to the authors. Anyway thanks for the attention and I am looking forward to the good news.
