The way that PLATO does 'go to next display' stuff is
that a screen clear not only clears the screen, it also
flushes any waiting output.  This is largely responsible
for the usability of the PLATO menu-driven system.
A flush-output system call is easily done;  I've installed
it on several systems.  I would think that such a capability
could easily be built into termcap and/or terminfo (if we ever get
that!) to provide fast stepping through ANY menu-driven system.
