Modes of RDMI parameters
Four modes of RDMI parameters are supported: In, Out, Return, and InList.
•Define In parameters for all parameters that are passed from the USoft application to the external component.
•Define a Return parameter for the value that is passed back from the component to USoft as a standard procedure. This value could be used to verify that an invocation has been successful, or it could be data that is used again by the USoft application, for example when the component is called to perform a complex calculation.
•Define Out parameters for all parameters passed back from the component to the USoft application, other than the Return parameter.
•Define one InList parameter for all non-mandatory (variable) parameters of a method.
