Comment 7 for bug 584093

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.
Regards, Felix
