Are functions implemented in csh on Sun?

[Tony Rems]

Hopefully this is a quicky.  I've got a 3/60 running SunOS 4.0.3
and I can't seem to find any documentation on how to implement
a function.  I tried Bourne and Korn shell syntax and regular
C syntax (heck, I even tried awk syntax), but it doesn't seem
to like it.  Anyone know if it's available?  If so, what's the
syntax.  If not, does anyone have a copy of the source that
does?  Thanks in advance.

e-mail would be fine.  Preferably to my Amdahl account.
