Hi Tore,

Yes, I was using an index.
In my loop I was perfoming

GO TOP && or LOCATE
GO BOTT

Now I've found that GO BOTT is what really takes a big time, and causes the delay...
Changing GO BOTT to SKIP +1 I have the expected results.

And now...
How can I perform a GO BOTTOM in the fastest way ?

Maybe
SET ORDER TO myIndex DESCENDING
and then
LOCATE ???

Regards

Cesar
