87D

Explanation
During processing of an EVENTS macro, the system
found that the EVENTS table specified in the event control block (ECB)
had no entries available for the posted ECB address.

System action
The system abnormally ends the program that issued
the EVENTS 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.
Search problem reporting data bases for a fix for the problem. If
no fix exists, contact the IBM® Support
Center. Provide the program listing and the assembly listing associated
with the job.

Programmer response
Ensure that the EVENTS table is large enough
to contain entries for all ECBs that can be posted to it.  Correct
the error.  Run the job again.
