PH63269: UNDER LP(64) THE COMPILER DOESN'T IMPLEMENT INTENDED AND SO DOCUMENTED ALLOCATE ... RETURNING POINTER-32 BEHAVIOR

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• (1) The usage ALLOCATE ... LOC 64 RETURNING pointer-32-item was
  intended to produce a diagnostic message as a POINTER-32 cannot
  address memory above the bar, but fails to do so.
  
  (2) The usage ALLOCATE ... RETURNING pointer-32-item (ie.
  without an explicit LOC 64) was intended to return below the bar
  
  memory as if LOC 31 had been specified, but returns above the
  bar memory.
  
  In both cases, memory is allocated from above the bar, and the
  address truncated to fit the pointer-32-item, likely leading to
  an ABENDS0C4 when the memory is accessed.
  

Local fix

• Use a POINTER rather than a POINTER-32, or if below the bar
  memory allocation is intended in an LP(64) program, explicitly
  specify LOC 31.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL 6.3 compiling and  *
  *                 running programs containing COBOL code with  *
  *                 the ALLOCATE statement when a user has the   *
  *                 LP(64) compiler option in effect and         *
  *                 data-name-2 references a USAGE POINTER-32    *
  *                 data item.                                   *
  ****************************************************************
  * PROBLEM DESCRIPTION: In the case described above, when LOC   *
  *                      64 is specified, a diagnostic message   *
  *                      was not being issued. In the case of    *
  *                      LOC phrase being omitted, the allocated *
  *                      storage was above the bar. This also    *
  *                      lead to an inconsistency between the    *
  *                      compiler and the documentation.         *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  When LOC 64 was specified the compiler did not issue an
  error message when it was expected according to the
  documentation, and when LOC 64 was not specified the
  ALLOCATE statement returned an invalid pointer.
  

Problem conclusion

• The compiler has been modified so that in the case described
  above,  when LOC 64 is specified the diagnostic message
  IGYPA3441-S will now be issued. When LOC 64 is not
  specified, the allocated storage will be below the bar.
