Is the problem that you have a local view without an index and
you are using Locate For which just scans through the records
becasue there is no index? Are the records sorted in the
order that people query them? I.e. last name?
Could you try wrapping a binary search around your grid search
using gotos? Essentially you do have some index (your sort order)
even if VFP doesn't know about it.

It always bugs me that you can't tell the system to 'assume the
natural order' is an index. It would allow you to take advantage o f
a sorted local view in a search grid by using Locate For if Locate
For assumed the natural order was an index.
