Creating server-side context for a ProcObject (running a persistent procedure)
Running an internal procedure or user-defined function
Creating a SubAppObject
Releasing an object
Running a procedure that passes a TABLE parameter
Processing the data from a TABLE parameter
Running a procedure that passes a TABLE-HANDLE parameter
Preparing the schema and data for an input TABLE-HANDLE parameter
Processing the schema and data for an output TABLE-HANDLE parameter
Extra processing required for RPC/Encoded TABLE-HANDLE parameters
Handling errors on the client
Notes: For more information on the concepts and procedures that underlie these tasks, see Chapter 4 "General Client Programming Model for Progress 4GL Web Services" and Chapter 5, " Sample Code with SOAP Messages for Progress 4GL Web Services."

OpenEdge comes installed with complete sample client applications that access 4GL Web services. For more information, see Chapter 6, " Sample Progress 4GL Web Services and Client Applications."
