<h2>First Input Parameter (Required)</h2>
The RPC Broker always passes a variable by reference in the first input parameter to your M routine. It expects results (one of five [[RPC_HELP_BROKER_RETURN_VALUE_TYPES|RETURN VALUE TYPEs]]) to be returned in this parameter. You must always set some return value into that first parameter before your routine returns.
