Information Supplied on Exit

R0-R13: Same as on entry
R14: Return Address
R15: Return Code

The exit routines must set one of the following return codes when returning:

RC=0: Indicates that no additional processing of the message is needed.
RC=4: Indicates that IATSIWO should send the message to the JES3 global address space for further processing. On the global, installation exit 70 is called to process the message.

If multiple exit routines exist for this exit, JES3 uses the highest return code set by all of the exit routines in determining whether the message should be sent to the global.

If an undefined return code is received, JES3 will perform default processing (RC=0).
