I second that question. I need to get a list of all tables that have names matching a certain regexp. I was able to find all tables with captions matching a regexp, but that way isn't robust since captions aren't linked to a table, they're just the preceding (or following) line. There doesn't seem to be a way to get the "logical name" of a table using the table handle returned by getTable.
I also second Bob's thanks to Jean Marie. Your quick responses have made my life a whole lot easier.
