The [t]csh builtin corresponding to [ba]sh's 'ulimit' is called 'limit':

A bit more verbose usage than 'ulimit', but has worked fine in all
FreeBSD versions where I've tried it. /usr/bin/ulimit obviously can't
work for changing the limits, why it (and /usr/bin/cd, /usr/bin/umask,
and a bunch of others like it) exists at all I'll leave for someone
else to explain (I think it's some POSIX requirement).

I think -d may also be worth a try...
