Agreed..and when you use a View the name (the Alias() ) will probably remain static...I had a case today where I used a Cursor to populate a Grid and added a column on the fly...the column added (although it had no ControlSource at all) came out as Readonly, which was perhaps because a Cursor is a readonly object...then I changed the Cursor to a temporary Table and the added column was ReadWrite...go figure...
The point is, I think Fox is doing things for us behind the scenes with Cursors vs. tables, that sometimes makes it more advantageous to use temporary Tables (unless you have Fox 7 and use the 'ReadWrite' option for Cursors...)
Just Rambling...

If you were to instead use the requery() on a view, the same filename is probably used (guessing, but 80% certain). In the case of the view, it is probably simply emptied and refilled with new data (kinda like a ZAP with an append from...) Using a view to populate the grid instead of a simple cursor, would prove to be a better approach because refreshing is almost automatic.
