  *                      1. Users who experience performance     *

  1. The compiler and runtime did not allocate and initialize
    WORKING-STORAGE efficiently
  2. The compiler generated inefficient instructions for some
    cases of indexed table references and large MOVEs of SPACEs
  3. The compiler was not detecting divide by zero with constant
    variables when the arithmetic was done at compile time.
  4. The compiler was not putting any information in the object
    code to help determine the address of the first instruction
    of the user code
  5. The compiler was not putting any information in the object
    code to help find the RETURN-CODE special register
  6. The compiler allowed the program to grow too much while
    inlining PERFORM statements during optimization
  7. The compiler put duplicate entries in the map of automatic
    variables in the listing file
  8. The compiler was not generating logic for detection of an
    ON EXCEPTION condition for programs compiled with the DLL
    compiler option and the programs contain one or more nested
    programs as well as CALLs to separately built DLL modules
  9. The compiler was not generating code to ensure complete file
    initialization occurred at alternate ENTRY points for programs
    compiled with the DATA(24) compiler option
  10. The compiler was not assigning names to some compiler
    temporaries in the LIST output of the compiler listing
  11. Some Japanese messages were incorrectly translated in the
    compiler diagnostic messages
  

Problem conclusion

• 1. Compiler and runtime were changed to allocate and initialize
   WORKING-STORAGE more efficiently for programs compiled with
   DATA(31) and RENT and NODLL, do not have XML-GENERATE or
   XML-PARSE, are not linked with such COBOL programs nor linked
   with C/C++ or PL/I programs.
   After this change, WORKING-STORAGE will be acquired from
   HEAP and the STORAGE and HEAP runtime options will have an
   affect on WORKING-STORAGE for programs that:
   -are compiled with DATA(24) or DATA(31) and RENT and NODLL
   -do not have XML GENERATE or XML PARSE
   -are not linked with such COBOL programs
   -are not linked with C/C++ or PL/I programs
  2. The compiler was changed to generate more efficient
   instructions in some cases of indexed table references and
   large MOVEs of SPACEs
  3. The compiler was changed to detect a divide by zero with
   constant variables when the arithmetic was done at compile time
  4. The compiler was changed to put information in the object
   code to help determine the address of the first instruction
  of user code.  See the following technote for details:
  http://www.ibm.com/support/docview.wss?uid=swg21648736
  5. The compiler was changed to put information in the object
   code to help find the RETURN-CODE special register
  See the following technote for details:
  http://www.ibm.com/support/docview.wss?uid=swg21648048
  6. The compiler was changed to limit the growth of program size
   while inlining PERFORM statements during optimization
  7. The compiler was corrected to not put duplicate entries in
   the map of automatic variables in the listing file
  8. The compiler was changed to generate logic for detection of
   an ON EXCEPTION condition for programs compiled with the DLL
   compiler option and the programs contain one or more nested
   programs as well as CALLs to separately built DLL modules
  9. The compiler was changed to generate code to ensure complete
   file initialization occurred at alternate ENTRY points for
   programs compiled with the DATA(24) compiler option
  10. The compiler was changed to add symbolic names for
   temporaries in the LIST output of compiler listing.
  11. The translation of some Japanese messages (from the
   English) was corrected
