There are several ways of doing this. Here is one:
set -q $COLUMNS $LINES; if test $status = 2; echo both defined; end
Note that this means that the man page for set is incorrect. It
currently says "exit status is the number of variables specified that
were not defined", but it the way it actually behaves for me is "exit
status is the number of variables specified that were defined".
