82A

Explanation
During processing of an ATTACH macro, the system
found an incorrect subpool specified by an authorized task with the
NSHSPV or the NSHSPL parameter. The authorized task is in system key,
supervisor state, or authorized by the authorized program facility
(APF).

System action
The system abnormally ends the program that issued
the ATTACH macro. The system does not create the new subtask.

System programmer response
If the error recurs and the program
is not in error, look at the messages in the job log for more information.
Search problem reporting data bases for a fix for the problem. If
no fix exists, contact the IBM® Support
Center. Provide the assembly listing for the job.

Programmer response
Change the incorrect parameter.  Only subpool
236 or 237 may be specified with the NSHSPV or the NSHSPL parameter.
Correct the error.  Run the job again.
