Looking for a way to conduct a find within a found set - presumably using a script - and not disturbing the found set the user is working with. I need to do this as there would be various ways that the found set was established, sometimes via various finds and sometimes by omitting records. Any ideas how this can be done?

Not experienced with this but I believe one way is to mark all the records in the initial found set in some way (such as using replace to place a '1' in a mark field). After any disruption of this set, it can be regained by searching for the marked records, OR by using a Go To Related Records. The latter might involve a global containing a '1', and relating that field to the mark field. Remember to clear the mark field when you're done with the initial set.

You may want to try using the "Modify Last Find" command.
