I just saw this link. it is of great interest to me right now...

I have this question... how do you add two of these Dwords?

how do i know if the add of two words overflows?
i.e. $1FFFE + $2E

my guess is to add the lower words $FFFE+$2E. But how do i know if there is an overflow? so that i can add one to the higher WORD? even worse..

i.e. $EFFF8 + $6FFE4

My guess again: add two lower words... if over flow add two higher words +1, else add two higher words....

I think i can manage myself once i am sure abour the overflow

Thanks,
