The conversation
The conversation between the front-end and the back-end transactions is held using the usual SEND, RECEIVE, and CONVERSE commands.
For programming information about these commands, see SEND (LUTYPE6.1), RECEIVE (LUTYPE6.1), and CONVERSE (LUTYPE6.1) .
In each of these commands, you must name the session in the SESSION option unless the conversation is with the principal facility.
