Dear d_labes,

You're absolutely right. Crappy implementation of SQL in SAS as usual, the function does not work even with a "group by" statement as ordinary arithmetic functions work. SAS "reads" data line by line and apply functions to each line. Therefore, this function seems even more useless than I actually thought.

Well, from my side I always use proc summary in log-transformed data to calculate geometric means and exponentiate the result. It's amazing how such a routinely used statistic is not avaliable as part of the "default" summary functions in SAS.
