>&#13;   First, when connecting, the function would first try to find a
   (persistent) link that's already open with the same host,
   username and password.  If one is found, an identifier for it
   will be returned instead of opening a new connection.

>&#13;   Second, the connection to the SQL server will not be closed when
   the execution of the script ends.  Instead, the link will remain
   open for future use (<A

   close links established by <B
