IEF757I

Explanation
The system found an incorrect data set name. The
data set name cannot consist of any special characters created by
the 12-4-9 multi-punch or in any other way that converts the value
of each character to X‘04’.

System action
The system ends the job and issues messages about
the job to the job log.

System programmer response
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 persists, search problem reporting
data bases for a fix for the problem. If no fix exists, contact the IBM® Support
Center.  Provide the SYSOUT output for the job.

Programmer response
Correct the data set name. Use other system
functions to access the data set. For example, code an authorized
program to read the job file control block (JFCB). Change the data
set name in the JFCB to the data set name containing the 12-4-9 multipunch,
be sure that JFCBNWRT is off in the JFCB, and issue an OPEN (TYPE=J)
macro using the modified JFCB.
