of creating the loop coding you reference
I'm not sure where I was convinced to go the structure route... If I
may ask, what is a typical scenario when you DO use a structure?

Yes!
What you should do is loop thru the multiple entries, and do a db
insert for each entry.
If you continue in the current direction (non-atomic) you will create a
nightmare --
Just consider what you (and the db engine) will need to do to find
records in the db:
-- All cassettes with an issue date between Jan o3 and Jun 03
-- display all cassettes in alphabetic order by title
If you are going to save a structure, you might as well save it in a
text file -- an rdbms won't offer much advantage.
