/* This is an example script showing query execution and error checking.
This script shows how to execute a simple database query, walk through
the results, and report problems to the user. It is designed to be used
as an initMenu script.
It queries the database for currencies without exchange rates for
the current day. As each row is returned, a message is displayed
for the user.
