You missed the point. PASSALL is ONLY ONE of the possible choices
which MAY be correct for a particular instance. A more general problem
is "What should be done right now with a control-<BLARGH> for this
particular user on this particular terminal type".
ie: should a form-feed be sent as a true form feed, as "n" line feeds,
as "m-n" line feeds (useful for dumb terminals with actual forms),
or should some more complex function be done such as...
wait for the user to send some special character
or send some special sequence to clear the screen, including
waiting both before and/or after. (before so it can be read
before the screen is cleared, after so the screen can settle
back down [ie: tektronix] before sending more text).
Depending on PERSONAL preference AND the particular TERMINAL TYPE,
make some decision about what would be NICE for the user. For those
terminals which clear when sent a form-feed it is clearly NOT correct
to send a form-feed with no delay, but for a hard-copy terminal which
understands form-feed it may be exactly what is needed.
