exec-ing a function

exec-ing a function

[Alan Watson]

This may be old hat to some, but after some confusion I have just
discovered that one can `exec' a function.  Perhaps a sentence in the
manual page would save others confusion.

Incidentally, I had an observing run at the Kitt Peak National
Observatory a couple of weeks ago.  Modern observing is not especially
fun -- you basically sit at a computer for 16h each night.  After a few
minutes with csh, I went looking in /etc/shells for the alternatives,
and to my pleasant surprise found rc (but, interestingly, neither ksh,
tcsh, zsh, or bash).  The Good News is spreading!

Alan.
