Hi Paul--

Sorry for the delay.  I meant to reply earlier but didn't.  Wanted to
smoke other people out. :-)

I have a set of IDL functions which implements ERF and ERFC, based on
the CEPHES library implementations of the same name.  I would be glad
to send these by email, since they are a little specialized for the
newsgroup, and are a little rough around the edges.  If I get any
other requests I would gladly put it on my web page.

Let me know.  Yours,
