As you wish, but please don't think you have to go to a lot of work on this. I didn't mean a full layout of functionality, just things like do you mark records that are changed, or also records that have only been examined, what about records that have been deleted, do you automatically clear all such flags on start-up or let them carry over into the next session - a few details like that.Sorry to take so long to respond but I realize I will have to describe the basic manner in which all my databases work and I'm trying to devise a reply that is shorter than War & Peace. Wii reply in full in due course.
