ok so, I have been working on this for a while, and I just need this last step figured out.

I want age at the hbv test (hbv2) and I have the date of birth (CDOB).

I do this code and get this output but obviously that isn't correct so what can I do to fix this

data want;
set have;
ageattest = hbv2 - CDOB;
run;

this is proc contents for the two variables

Variable Type Len Format Informat Label

hbv2

Num

YEAR.

CDOB
