Really. Termcap, termcap... let's see what the manual says:

	tgetent, check.
	tgetnum, check.
	tgetflag, check.
	tgetstr, check.
	tgoto, check.
	tputs, check.

	tparm... um...

Not in Xenix/286, let's try System V.2... It's under "curses... termcap
emulation".  OK:

	tgetent, check.
	tgetflag, check.
	tgetnum, check.
	tgetstr, check.
	tgoto, check.
	tputs, check.

	tparm... um...

Someone's swiped my V.3.2 manuals, but nm /usr/lib/libcurses.a shows there
*is* an entry for tparm. So it showed up in V.3.2. After some digging, I found
it in SunOS but not in BSD. Under the System V compatibility library. Yep,
it's a V.3 thing.

Now if this was comp.unix.sysv386 you might have a point.

It's used for expanding "cs", too, at the very least.

Whose manual?

If you're using termcap in the first place, rather than terminfo or curses,
portability is obviously a concern. In that case it behooves you to use the
least common denominator.

tgoto.
