A conversation between CA IDMS/DC and another LU can be terminated in the following ways:

• Your program can request a normal termination of the conversation by specifying OPTNS=LAST on a write request.
• Your program can notify the remote LU that it is terminating abnormally by specifying OPTNS=ABEND on a write request.
• The remote LU can terminate the conversation. CA IDMS/DC sets the UIOLST (send last received) flag in the UIOCB.

Your program must specify the LTE address of the remote task (UIOLTEA) to identify the conversation.

The session that is being maintained between CA IDMS/DC and the remote LU is not closed, but remains available to be allocated to another conversation. This eliminates the overhead of reestablishing another session.

If you want to start another conversation after you have ended the current one, you must allocate a new conversation to the session.

Note: For more information about allocating a conversation, see Allocating a Session in this appendix.
