Thanks for the reply. This is my first _reply_ to the list, and IIUC,
this list advocates replying to both the list and individual. If I'm in
error, please let me know.

This seems like a very good idea. I think I have another reply from
someone else who suggested php, (a quite similar idea, right?). So
perhaps this would be a good idea. FWIW, with my current application,
I'm using groff to do the formatting.

With the above and below suggestions, I take it you suggest building the
interfacing into two separate modules, so to speak.. one for inputting
and one for outputting. For the above, would it be best to create an
app or could all this be done from within psql, or another tool?

Yes, I have many of them archived for future reference. At this time, I
have to take it slowly because many of the concepts are still a bit
vague to me, and I'll have to gain a bit more familiarity before it all
becomes clear.
