I'll try a variation on what the others have said...

SCATTER/GATHER were absolutely necessary in FPD/FPW.
With VFP, though, there is a combination of two things that handily replace their need: ControlSource property and buffering (preferably "TABLE" buffering).

The ControlSource names the source/destination of a field to be shown in a control like a textbox, typically a field of a table.
Buffering ensures that the ControlSources that have been changed by an operator at a terminal DO NOT actually go to a file until you do a TableUpdate() on the relevant table(s) (or move the record pointer in the case of "ROW" buffering.

I hope this puts you on a track that helps.

New, Save, Cancel I've got a handle on OK, but can someone point the way to edit nirvana, I don't mind the rigors of the journey, I'm just not seeing the path.
