<!-- Brief Description blurb. -->
This is a simple example demonstrating how to transactionally
update a SQL 6.5 database using ADO and Transacted ASP.
The example will obtain information regarding a book sale from
the SQL 6.5 "Pubs" database. It will then increment the quantity
of books sold by one, as well as change the zip-code of the store
in which the book was sold.
<p> Because the two database operations are wrapped
within a shared ASP Transaction, both will be automatically rolled
back to their previous state in the event of a failure.
