22C

Explanation
During processing of a CHAP macro, the system found
that the address of the fullword specified in the second operand is
incorrect.  This fullword contains the address of the task control
block (TCB) for the subtask whose priority was to be changed.
The
address was incorrect for one of the following reasons: It was not a multiple of 4.
The addressed virtual storage has not been allocated.
The protection key of the fullword does not match the protection
key of the issuer of the CHAP macro.

System action
The system abnormally ends the program that issued
the CHAP macro.

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.
Format a GTF trace, using trace option keyword TRACE=SVCP and using
event keywords SVC=44,END.
Search problem reporting data bases
for a fix for the problem. If no fix exists, contact the IBM® Support Center.  Provide the source program
listing for the job.

Programmer response
Change the CHAP macro to specify a valid
fullword address. Ensure that this fullword will contain the address
of the TCB when the CHAP macro is processed. Also, ensure that the
problem program does not incorrectly modify the specification. Correct
the error. Run the job again.
