there is a well known csh bug that evaluates all
conjunctive conditionals in an if statement. the
if statement in /usr/athena/lib/init/init_aliases
fails on that bug as follows:
% rsh paris date
---> term: Undefined variable.

this is due to line 18:
if ($?term && $term =~ xterm*) then
evaluating the $term regardless of whether the
$?term evaluates true or not.
fix follows.
