- I have some data containing between n and m observations in each
- of C conditions. I would like to have exactly n observations in
- each condition, so that my design is balanced: I'm fairly happy that
- discarding the excess observations shouldn't change things too much.
- My question: can anyone suggest a way to discard the excess
- observations in a SAS data step, and to number the remaining
- observations 1...n for each condition.

- Thanks
