Using Parentheses
To change the priority of processing, parentheses can be used to link multiple With clauses. For example, the command:
List CUSTOMERS (With STATUS = 'A' Or With STATUS = 'P') And With CITY = 'LOS ANGELES'
will find customers who are either active or potential, and additionally live in Los Angeles. Customers outside Los Angeles, or those who are in Los Angeles but not active or potential, are ignored.
