3.3.1.2 Algorithm for Constructing Method Invocation Parameter Sets

The parameters for a given method call define how the message for that method call is constructed. The RDS Transport Protocol uses the right-to-left arrangement for parameters. For a call to the method, the right-most parameter is constructed into the message. The parameters are appended one after the other. On a method call, all input parameters are appended in the order described in rdsParameters (section 2.2.2.6).

To return the results of the method invocation, the server appends all parameters in right-to-left order. The return value of the method invocation is included in the rdsMethodResponse (section 2.2.2.2).
