Command: $CLOSEWINDOW
Function: Closes any windows which you may have open on the Maxs Screen. You
must do this BEFORE your AREXX program ends. MaxRexx has been
programmed so that if you issue this command twice, it should not
crash.
Results:
If rc=0 then the window closed fine
If rc=-1 then the window failed to close, or there was no window open
to close.
