002

Explanation
For all return codes except 2C, the error occurred
while the control program was processing a sequential data set with
BSAM or QSAM, or creating a direct organization data set.  This system
completion code is accompanied by message IEC036I.  Refer to the explanation
of message IEC036I for complete information about the task that was
ended and for an explanation of the return code found in register
15.
For return code 2C, the error occurred while the control
program was opening an ISAM data set for QISAM load mode.  Too many
tracks were specified for cylinder overflow, or DCB BLKSIZE was not
a multiple of DCB LRECL, or DCB BLKSIZE was greater than the track
size.

System action
For all return codes except 2C, pertinent control
blocks are written to the GTF trace data set, the user's DCB ABEND
exit is taken if one is provided, and message IEC036I is issued.

Operator response
Start a generalized trace facility (GTF) trace,
and re-create the problem.  Reply to message AHL100A with:      TRACE=SYS,USR,SLIP

On
the DD statement for the data set in error, specify:      DCB=DIAGNS=TRACE

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 JCL and the program listing for the job.

Programmer response
See message IEC036I for the appropriate
responses for each return code except 2C.  For return code 2C, change
the CYLOFL operand of the DCB macro instruction to reflect the correct
number of tracks, or correct the DCB BLKSIZE.
