Paul,

Thanks very much for your reply.  I understand only
a fraction of the suggested solution.  I will need to
digest this a bit, and do some more background reading
on templates.

My initial, naive attempts to use this in a simple main()
were unsuccessful.  I'll keep plugging at it ...

Best Regards,
James
