Jacob,
Are you just clearing the screen in an otherwise scroll-oriented
program, or are you doing graphics by clearing and repainting a similar
screen when something changes?
The termcap "cl" method is perfect for the former, but curses is better
suited for the latter.

I'm actually running an old CIT-101 from c.itoh.
The pdp11 is
currently just simh on a raspberry pi, but I have a lot of pdp11
hardware in various states of disrepair. my 11/73 ran 2.11bsd nicely
has a burned out power supply and I haven't been able to fix it.
I checked out the curses man page in 2.11 and tried to use curses
clear, but it really does tack on a lot of overhead & slows things
down. So I'm now tempted to just cheat, keep it simple, find a simple
escape string that works on real vt100s as well as xterms, etc. and
just printf it.

Ah - that makes sense, and since VT-100 are not fully ANSI,
that's likely why it's not listed in my circa 1976 VT-100
programmers manual and probably why it does not work for Jacob. ;-)

The sequence ESC-c is ANSI X3.64 for "reset to initial state"

happens to clear the screen, among other things. I still use it
frequently to reset Mac OS X "Terminal" windows to a sane state,
manually entered.
