APAR status

• Closed as program error.

Error description

• Customer reports that when compiling a COBOL program with LP(64)
  and the source directive >>DATA 31, a Working-Storage item is
  placed above the 2 GB bar when a REDEFINES is present.
  
  The same item is placed below the bar when the REDEFINES is
  removed.
  
  The customer is using IBM Enterprise COBOL for z/OS V6.5.0
  P260320.
  
  Testcase located in:
  CBLSERV.T02211.S2788.TESTCASE
  
  Where you can find a simple program and a JCL where the behavior
  is recreated.

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL 6.4 compiling and  *
  *                 running programs with the LP(64) option in   *
  *                 effect, where the program contains a data    *
  *                 item under the scope of a 'DATA 31'          *
  *                 directive and the data item is redefined by  *
  *                 another data item.                           *
  ****************************************************************
  * PROBLEM DESCRIPTION: Incorrect runtime behaviour, including  *
  *                      a possible runtime abend, due to the    *
  *                      data item being located above the 2GB   *
  *                      bar instead of below it.                *
  ****************************************************************
  * RECOMMENDATION: Apply the IBM-provided PTF.                  *

  The compiler was not correctly applying the DATA directive to
  redefined data items.
  

Problem conclusion

• The compiler was updated so that the DATA directive is properly
  applied to redefined data items.
