Final register contents

The routine must leave the register status as follows:

Registers 0–14:

Restored to entry contents.

Register 15:

Return Code:

0: Processing successfully completed; continue termination.
X'01'–X'7F': For return codes greater than zero, exit processing did not work. The session management exit remains active.

In addition to these specific return codes, there are other codes that control the exit's disablement. See Final register contents for more information about those codes.

If VTAM® cannot find the new session management exit when it tries to load the exit, VTAM issues message IST985I.
