Sample C++	Example of object creation in an RTR server program.
server code

void CombinationOrderProcessor::StartProcessingOrdersAtoL()

1,//Length of the key. OffsetIntoApplicationProtocol, //Offset value.

"A",	//Lowest ASCII value for partition.
"L");	//Highest ASCII value for partition.

//Create an RTRData Oobject to hold each incoming message or event. This

//object will be reused.

//

//Continually loop, receiving messages and dispatching them to the handlers.

RTR C	You can use the C programming interface to write C applications
Programming	that use RTR. For more information on the C programming
Interface	interface, see the RTR C Application Programmer's Reference
	Manual and the RTR Application Design Guide.
	Snippets from client and server programs using the RTR C-
	programing API follow and are more fully shown in the RTR
	Application Design Guide.
