PROC Star

Do you have a question?

--------------------------
The hash OUTPUT method will overwrite a SAS data set, but not append. That can be costly. Consider voting for Add a HASH object method which would append a hash object to an existing SAS data set

Would enabling PROC SORT to simultaneously output multiple datasets be useful? Then vote for
Allow PROC SORT to output multiple datasets

Your sub-query doesn't know about columns created in the outer query, so you need to replicate the logic from the outer query in your sub-query.

I don't know your requirement, but I would guess you wnat to have a GROUP BY in your outer query, or what is your desired en result?
