Yes, that works [ =CursorSetProp('Buffering',5,'ap_wires_work_orders') ]
and after the replace all is complete, I do a Tableupdate()

but when I try to close the file or do a requery() to look at the changed data, it says Table Buffere for alias "MyView" contains uncommited changes

The when I close and reopen MyView, teh data is back to the original state.
