To prepare external components that can be invoked by a USoft application, you need to know how to use the component technology (COM). Methods exposed by your components can be invoked from a USoft application through RDMI.

In the following cases your component must be specifically written against USoft's query protocol:

· The component's return value must be interpreted as "record(s) found" or "no record found"


· The component returns more than one value or record per input record.
