Since no one replied by now I assume there won't be an answer to my
questions. No problem. If anyone does respond sometime between now and
the solar expansion projected to occur in a few billion years or so,
please include my email address in the response. Since I have a tenuous
connection with SAS (virtually none at the time) I need to set SAS-L to
NOMAIL whenever I have no reason to get messages. I will do this by the
end of the day.
