PH64923: AT OPT(2) IGYCB7315-W REFERENCE MODIFIER WITH A NON-POSITIVE VALUE PRODUCED DESPITE CORRECT REFERENCE MODIFIER

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• With optimization, the compiler is in some case miscalculating
  reference modification related addresses for purposes of
  validation, leading to the IGYCB7315-W message.
  
  If the compiler subsequently combines statements for which an
  IGYCB7315-W message was issued, there can be apparently
  spurious multiple instances of such a message for the same
  statement.
  

Local fix

• Compile at OPT(0) or OPT(1).
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL 6.3 compiling      *
  *                 complex programs with OPT(2) that contains   *
  *                 reference modifications to data items        *
  *                 defined in WORKING-STORAGE.                  *
  ****************************************************************
  * PROBLEM DESCRIPTION: Compiler issues message MSGIGYCB7315-W  *
  *                       A REFERENCE MODIFIER WITH A            *
  *                       NON-POSITIVE VALUE WAS FOUND.          *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF                       *
  ****************************************************************
  In rare cases, the compiler incorrectly calculates the
  starting position of the reference modification in a data item
  defined within WORKING-STORAGE.
  

Problem conclusion

• The compiler has been fixed to correctly calculate the start
  position of the reference modification into a data item in
  above cases.
