Right.  I wasn't trying to imply otherwise.  That's why Pavel Curtis
could use BSD curses as a basis for his pcurses.

It is only System V curses that was encumbered.  And now it too is
available for inspection, if in a somewhat gray area for anyone with
commercial ambitions.

Agreed.  I've seen no claim anywhere to the contrary.

Yes.  This too is my understanding.  terminfo is a better API (and
source format) than termcap, but I also surmise that better support for
deployment environments with large "fleets" of video terminals was also
seen by AT&T management as an enticing prospect for vendor lock-in.

Thank you for the confirmation.  And for supplying some coaching all
those years ago--we're still enjoying the benefits today!
