Hi Jory,

   Thanks very much for your reply concerning solving of equations (with
natural logs in them).  You've probably read my general reponse, which
shows that in my application a lookup table (not huge) would be plenty
sufficient for what I am trying to do.  But I would be interested in the
topic of finding easy PICable ways to do natural logs if the information
is readily available.  I'd hate to have somebody spend an hour digging
through their attic.

   Thanks again,

   Jim Johnson
