PH06049: INCORRECT STATEMENT NUMBER FOR ABEND IN FAULT ANALYZER OR DEBUG TOOL

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• A decimal divide exception s0CB may appear on an incorrect line
  number when using IBM Fault Analyzer or IBM Debug Tool for
  z/OS. Problem occurs when compiling the COBOL program with
  NOTEST(DWARF), OPT(2), and ARCH(10) or ARCH(11).
  

Local fix

• Compile with ARCH(9)
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL V6.1 compiling     *
  *                 programs with TEST(DWARF) and ARCH(10|11)    *
  *                 that do a PACKED-DECIMAL or USAGE DISPLAY    *
  *                 division by zero.                            *
  ****************************************************************
  * PROBLEM DESCRIPTION: The abend appears to be on an incorrect *
  *                      line number when using IBM Debugger     *
  *                      for Z or Fault Analyzer.                *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  At ARCH(10|11), the compiler may use decimal floating point
  (DFP) to improve performance of PACKED-DECIMAL or USAGE DISPLAY
  arithmetic. The DFP division instruction generates a different
  abend for a division by zero than the PACKED-DECIMAL division
  instruction. To ensure the abend is the same when using a DPF
  division instruction, the compiler first tests the divisor, and
  when the divisor is zero, it generates an intentional packed
  division by zero. That division by zero is out-of-line from the
  rest of the division code. The first out-of-line instruction
  shares an offset with the return instruction, causing it to
  appear on a different line in IBM Debugger for Z or Fault
  Analyzer.
  

Problem conclusion

• The compiler was fixed to insert a dummy instruction between the
  return instruction and the first out-of-line instruction, so
  the out-of-line instructions appear on the correct line number.
  

Temporary fix
