st: RE: list subjects with a similar value
Maybe try something along these lines:
duplicates tag dateofbirth, gen(tag)
drop if tag==0
sort dateofbirth
by dateofbirth: list id

Subject: st: list subjects with a similar value
Hi,
I have a large database and would like to list the idnumber of all
subjects with the same date of birth. How do I do this? I have tried
.duplicate, but can figure out how to do it. Thanks.
Raoul
