The API function call EDARPC enables a client application to call a compiled program stored on the server.

The program is called in the following ways:

• Directly, with EDARPC specifying the program name.
• Indirectly, with EDARPC specifying the name of a Dialogue Manager procedure that, when executed, calls the program using one of the following commands:
  • CALLPGM
  • EXEC
  • SQL EX

  The command EXEC functions the same way as CALLPGM, except for the difference in execution order requirements as described in Execution Order of Stored Procedures From Dialogue Manager. For simplicity, this chapter refers only to CALLPGM when both CALLPGM and EXEC apply. The SQL EX method has the advantage of being able to also apply intermediate processing to the initial results set before passing the final answer set to the calling request.

The term program is also used to refer to a compiled program.

The following figure illustrates calls to programs made from EDARPC and Dialogue Manager.

The following figure illustrates the libraries in which compiled programs and Dialogue Manager procedures reside. See Introducing Stored Procedures, for details on stored procedure libraries and stored procedure execution order.
