IEF321I

Explanation
In an input data set, a variable record extension
(VRE) segment descriptor word is incorrect. For example, a beginning
segment occurred before the end segment of the last logical record.

System action
The External Writer closed its output data set
and stopped itself.

System programmer response
Probable user error. Make sure the
segment descriptor words in the input data set are being created correctly.
Then execute the job step again.
Obtain the program listing
for the job. Look at the messages in the job log.  If the JOB statement
did not specify MSGLEVEL=(1,1), specify it and run the job again.
If
the problem recurs and if the program is not in error, search problem
reporting data bases for a fix for the problem. If no fix exists,
contact the IBM® Support Center.
