Here is what I have come up with
Names Default To Here( 1 );
dt = Current Data Table();
df = dt << Data Filter;
Wait( 2 );
Window( "Data Filter for " || Char( dt << get name ) ) << Close window;
Unless you are interactively changing the Data Filter values there is probably a better way in JSL to perform the tasks. What specifically are you using the data filter for?
