And just to follow up...
I should have clarified my question.
I was looking for the occurrence of ID (and its associated date) with the highest rank FOR THAT PARTICULAR ID. FWIW, I assumed NO relationship between date and rank (although in looking at my _data_ more closely, I realized there was!).
Dan Clamage's point about indexing is well taken, and Jonathan Gennick's code provided the selection logic I needed.
Thanks again. Received on Thu Oct 30 1997 - 00:00:00 CST
