>>Well, let's suppose that you want to undo and redo an entire record. Before doing the "undo" (as part of the function that invokes the TableRevert()), you would have to save the modified record values somewhere. scatter name comes to mind, but I am not sure whether you could scatter to a form property.

I tried the following, which gave me an error message (VFP6/SP5):
ThisForm.AddProperty("aNewValues(1)")
scatter name ThisForm.aNewValues && "Syntax error" at runtime
I assume it is necessary to copy to a regular array first.
