Asynchronous remote procedures
If you run a remote procedure asynchronously, the client application continues execution immediately after the RUN statement that invokes the remote procedure completes. The remote procedure executes on the AppServer whenever the AppServer is available to execute it. You can then access the results of the remote request in an event procedure that executes in response to a PROCEDURE-COMPLETE event. The client handles the event in the context of a PROCESS EVENTS or other blocking I/O statement, similar to a user-interface event, and executes the event procedure like a user-interface trigger.
