program for addition of two bcd numbers

[MAHESHDEEVELA]

 hi i have the doubt on addition of two bcd numbers any one can post program for bcd addition

[Frank Kotler]

Ahhh... I almost remember bcd. Seems to me we used an ordinary integer "add" and then followed it with one of those "adjust" instructions, no?

Code: [Select]

mov al, 9
add al, 8
daa  ; or aaa?
Something like that? But I recall that the point with bcd was to do multiple digits - maybe "many" digits.

Do you have a clear idea what you want to do? (the "customer specification" otherwise known as the "assignment")

Best,
Frank
