AFAIK, there's nothing in VTAM that would be affected by a change in
screen geometry. VTIOC is fairly small and TIOC is dead. Yes, TSO has
multiple TCB's, but other than SM I'm not aware of any TSO code that
is affected by screen geometry. It's ISPF that is the problem.
All of the plumbing is in place for a TSO command to recognize and
respond to a change in geometry.
