Cetin,

Your example works exactly as I would have expected. My application whould be performing in the same manner. When I set key to 6 and seek as in my example I should find the record that is there with that key. I am not sure why it would fail. Doesn't seem like it should. I am going to go back and validate the databse, reindex and see it the results change. As I do this rather often I don't think they will but it is worth a shot.

Have you or anyone selse seen seek( x, file, tag) fail while set key is in place before?


>"Set key" is a kind of filter on index. It limits access to part of index. If your seek() falls in that range of "set key" then seek() returns .t. (you limit seek to a range).
>ie: home()+"samples\data\customer" has country and contact indexes.
>

set order to tag country
>set key to "GERMANY" && Only upper(country) = "GERMANY" is accessible
>?seek("Janine Labrune","customer","contacts") && .f.
>set key to   && Remove limitation
>?seek("Janine Labrune","customer","contacts") && .t.

If applicable set key seems much faster than filter.

I saw another message about SET KEY and thought that maybe this would be better for what I was doing. I played around with SET KEY and found the things that I outlined in my message.
