OOPS is indeed an expression of surprise, but from the Termcap routine
tgoto(), not Curses. Which also explains why Terminfo does not exhibit the
problem.

It is documented in an older V7 TERMCAP(3) manpage:
`If a % sequence is given which is not understood, then tgoto returns OOPS.'

Most notably, OOPS appears when the CM capability is absent (as is the case
with plain tty mode). Curses knows enough to just output spaces and newlines
if it receives OOPS from tgoto, but programs making direct Termcap calls
may not know to check for this (as appears to be the case with FoxBase).
