That may have solved the problem, but it seems a bit weird to me. From
the tcsh man page:
$?name
${?name}
Substitutes the string `1' if name is set, `0' if
it is not.
So if $TERM_PROGRAM is undefined as is the case, the test becomes:
if ("0" == "Apple_Terminal") then
alias settermtitle ...
endif
Which gets rid of the undefined variable error. However it makes the
test always fail, since "0" or "1" is never equal to "Apple_Terminal".
So making the suggested change will probably mean that the title never
gets updated. No big loss, but the 'correct' fix would be to test for
undefined and handle that.
