Why? The correct response to a change in geometry is to write a READ PARTITION (QUERY) and to adjust to the new screen geometry. That should elimenate the garbage whether the new size is smaller, larger or the same.
There is no formal mechanism to let TSO announce a change in screen size. The closest would be an error on the terminal due to a screen size modified to a smaller character count. So an I/O error on a TPUT might justify the Query, assuming the program can copy with the results, but a TPUT without error, to a larger screen size, may go undetected except by the viewer.
Whether or not an error occurs also depends on the interface. A local non-SNA may not produce an error, and even the more obvious case where a session is suspended and the user does a RECONNECT from a different geometry is not addressed.
