OA43114: ISRSUPC (ISPF SUPER COMPARE) ABENDS WHEN ONE OF ONE (CONCATENATION) FILE IN THE CONCATENATION IS NOT INITIALIZED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When running ISRSUPC (ISPF Super Compare) in batch and when
  NEWDD
  and/or OLDD contains more than one file (concatenation) and when
  one of
  the files in the concatenation is not initialized (e.g.
  BLKSIZE=0 ...),
  we receive message IEC141I 013-34 (or IEC141I 013-60) followed
  by an
  S0C4.
  
  The IEC141I messages seem ok because the file is not
  initialized.
  However, the S0C4 abend is not expected.
  

Local fix

• Don't use uninitialized files
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All ISPF Users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: If SuperC was processing a              *
  *                      concatenation of sequential data sets   *
  *                      and the second or subsequent data set   *
  *                      was uninitialized, this (correctly)     *
  *                      caused an abend 013 during EOV          *
  *                      processing with message IEC161I 013-34, *
  *                      but this was immediately followed by an *
  *                      0C4 in SuperC.                          *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  If an abend occurred during EOV processing, when switching from
  reading one concatenated data set to the next, the DCB abend
  exit provided by SuperC trapped and handled the abend, with the
  result that EOV processing closed the DCB.  The code which was
  reading the data set failed to allow for this possibility, and
  tried to read the next record from a closed DCB, causing an 0C4
  abend.
  

Problem conclusion

• SuperC input processing logic has been modified to check whether
  the DCB is still open after reading each record.  If not, it now
  sets the same indicators as for an I/O error, which will cause
  SuperC to terminate with return code 16 and an appropriate
  message, for example as follows: ASMF059E A SYNAD ERROR
  INTERCEPT ON THE NEW-FILE/DATA SET IS AN I/O ERROR,
  CONCATENATION-ORDERING OR ATTRIBUTE CONFLICT.
  
  This corresponds to HLASM Toolkit Feature SuperC APAR PM90235.
  HLASM Toolkit Feature SuperC APAR PM89747 is also included.
