PH72936: COBOL 6.5 ABENDS WITH A S0C4 IN Z/OS BATCH WHEN SYSIN DD POINTS TO ZFS FILE WITH JULY 2026 PTF

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The IBM Enterprise COBOL compiler (IGYCRCTL) ABENDs with system
  completion code S0C4 reason code 00000011 (storage protection
  exception) when the SYSIN DD is allocated using PATH= to a zFS
  file instead of a traditional DSN= PDS member. The crash occurs
  during compiler initialization, before any compilation begins.
  No active module is found in the symptom dump, indicating the
  fault occurs in the OMVS kernel path during the zFS file open.
  

Local fix

• The issue is located on July 2026 PTF. Use a different version
  as a workaround.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL 6.5 compiling      *
  *                 COBOL programs where the SYSIN DD has been   *
  *                 allocated to Unix file, and the user is NOT  *
  *                 using cob2. The user may, for example, be    *
  *                 invoking the compiler from JCL with the      *
  *                 SYSIN DD is pointing to a Unix file.         *
  ****************************************************************
  * PROBLEM DESCRIPTION: The compiler abends with system return  *
  *                      code 0C4 when invoked from JCL and the  *
  *                      SYSIN DD has been allocated to a Unix   *
  *                      file.                                   *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  The compiler erroneously processes the SYSIN DD when it is
  allocated to a Unix file, and the compiler was invoked via JCL
  (or in an environment where no Unix file descriptors already
  exist), resulting in a compiler ABEND.
  

Problem conclusion

• The compiler was rectified to correctly process the SYSIN DD in
  the above situation.
