<h2>Tutorial: Introduction</h2>
The major functions of a [[RPC_HELP_TRPCBroker|TRPCBroker]] component in a Delphi-based application are to:
* Connect to an RPC Broker VistA M Server system from a client.
* Execute remote procedure calls ([[RPC_HELP_RPCs|RPC]]s) on that system.
* Return data results from RPC to the client.

This tutorial guides you through using a [[RPC_HELP_TRPCBroker|TRPCBroker]] component to perform each of these tasks, by having you create a Delphi-based application, step-by-step. This application will retrieve a list of terminal types from the VistA M Server, and display information about each terminal type.

After you have completed this tutorial, you should be able to:
* Include a [[RPC_HELP_TRPCBroker|TRPCBroker]] component in a Delphi-based application.
* Retrieve the end-user client workstation's designated VistA M Server and port to connect to.
* Establish a connection through the RPC Broker component to an RPC Broker VistA M Server.
* Create M routines that return data in the formats necessary to be called from RPCs.
* Create RPCs.
* Call RPCs from a Delphi-based application to retrieve data from a VistA M database.
* Pass parameters from your Delphi-based application to RPCs.
