Frankly SET FILTER has always been fast - except for those who know nothing of Rushmore and of course also except for the grid. It is my opinion that the grid initial coding did not take Rushmore into account. Only in VFP 9 did this get addressed. Of course by now lots of people know not to mix SET FILTER and grids, but then again, some people still don't.

>I haven't used filters for a table of any significant size in ages. Love those parameterized views. However, I could swear that I recently came across something that was saying that in VFP 9 (or whatever it said - a recent version) the filters were now very fast and this made them useable again. Wish I could remember where I saw that (or perhaps I was hallucinating). Have you heard anything like that (I guess not based on your reply).
