Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of the IBM Automatic Binary        *
  *                 Optimizer (ABO) for z/OS, v1.2 and v1.3      *
  ****************************************************************
  * PROBLEM DESCRIPTION: In rare situations compiled programs    *
  *                      containing DIVIDE or MULTIPLY           *
  *                      statements may be optimized             *
  *                      incorrectly by ABO.                     *
  *                                                              *
  *                      In the rare cases where the problem is  *
  *                      present it is most likely to occur for  *
  *                      programs where :                        *
  *                      - the OPT(STD) or OPT(FULL) compiler    *
  *                      options were used to compile the input  *
  *                      program to ABO                          *
  *                      - the DIVIDE or MULTIPLY statements     *
  *                      were operating on large enough packed   *
  *                      or zoned decimal data items so the      *
  *                      operation was handled by the library    *
  *                      routine IGZCXDI or IGZCXMU in the       *
  *                      original compiled program               *
  *                                                              *
  *                      The symptom may be an unexpected        *
  *                      IGZ0061S division by zero message for   *
  *                      DIVIDE statements but other unexpected  *
  *                      behavior, abends and results are also   *
  *                      possible.                               *

  ABO was modified to correctly optimize these modules
  

Problem conclusion

• The ABO optimized module now behaves correctly for these DIVIDE
  and MULTIPLY statements
