Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL 6.3 and later      *
  *                 releases running AMODE 64 COBOL programs     *
  *                 which make dynamic calls to AMODE 31         *
  *                 COBOL subprograms in a mixed                 *
  *                 AMODE 31 and 64 Language Environment (LE).   *
  ****************************************************************
  * PROBLEM DESCRIPTION: In mixed AMODE LE,                      *
  *                      when AMODE 64 COBOL programs            *
  *                      make dynamic calls to AMODE 31 COBOL    *
  *                      subprograms, the callee must be a DLL.  *
  *                      The existing COBOL Runtime support      *
  *                      does not allow non-DLL AMODE 31 COBOL   *
  *                      subprograms in this scenario.           *
  *                                                              *
  *                      This DLL requirement is lifted with     *

Problem conclusion

Temporary fix

Comments

• NEW FUNCTION.
  
  The PTF for PH59864 (this APAR) pre-reqs the PTF for
  LE APAR PH56800.
  
  https://www.ibm.com/support/pages/apar/PH56800
  
  LE 2.5 PTF ID that contains APAR PH56800 - UI94730
  LE 3.1 PTF ID that contains APAR PH56800 - UI94729
  
  This APAR allows non-DLL AMODE 31 COBOL subprograms
  dynamically callable by AMODE 64 COBOL callers.
  
  When PTFs UI94730/UI94729 and COBOL Runtime PH59864
  (this APAR) are installed on z/OS 2.5 or later systems where
  COBOL programs are run, the AMODE 31 subprograms can be either
  a DLL or a non-DLL.
  
  If the AMODE 31 non-DLL subprograms are run on systems
  where the required PTFs are not installed, the programs might
  abend or the result is unpredictable.
