Routine for packed BCD addition

[tom12sg]

Hi,

Anyone has done addition of packed BCD digits?
Any routine to share.

say: A=678156 (packed in three bytes)
B=034521 (packed in three bytes)
result sum in packed BCD too.

Can I do the addition straight without the need to convert into binary first?

Regards,
Tom
