PH46565: S0C4 IN IGZXLPKD MODULE QX11 ON CLOSE OF QSAM FILE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When a CLOSE is issued for a file that has reached end of
  volume, a s0c4 in QX11 offset x'32' may occur instead of the
  expected sB37 or sD37 abend.  An unexpected save area was passed
  into the DCB exit routine (QX11), resulting in the s0c4
  exception when using registers from this unexpected save area.

  * USERS AFFECTED: Users of Enterprise COBOL 5 and later        *
  *                 releases writing to a QSAM file with more    *
  *                 records than the file can handle and         *
  *                 closing the file afterwards.                 *
  ****************************************************************
  * PROBLEM DESCRIPTION: The COBOL program may terminate with    *
  *                      an 0C4 abend in the COBOL Runtime       *
  *                      program QX11 (module name IGZXLPKD)     *
  *                      rather than a SD37/SB37 abend           *
  *                      indicating that the file system is      *
  *                      out of space.                           *

  ****************************************************************
  When more than the maximum number of records that a QSAM file
  can hole are written to that QSAM file, the COBOL Runtime issues
  a QSAM CLOSE statement and upon return of the QSAM CLOSE, the
  NAB/DSA is not setup correctly in the COBOL Runtime causing a
  possible 0C4 abend.

Problem conclusion

• The COBOL Runtime has been fixed to setup the correct NAB/DSA
  upon return from the QSAM CLOSE statement so that processing can
  proceed as expected.
