0D8

Explanation
A space switch exception occurred.  A program issued
a Program Call (PC), Program Return (PR), or Program Transfer (PT)
instruction, but the cross memory resource ownership task in the target
address space has ended. The target address space is not the home
address space of the program that issued the PC or PT instruction.
The program interruption code if X'1C'.

System action
The system abends the program that issued the
PC, PR, or PT instruction.

System programmer response
Look for a problem with the PC/AUTH
macros that established the cross memory service being used by the
failing program. Correct any problems in the program and resubmit
it.
If no problems were found or if the problem recurs, search
problem reporting data bases for a fix for the problem. If no fix
exists, contact the IBM® Support
Center.
