PH24343: THE PROGRAM DOES NOT HAVE A S0C9 ABEND WHEN EXECUTING THE CODE FOR THE DIVIDE STATEMENT.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• USERS AFFECTED: Users of Enterprise COBOL V6.x compiling
  programs with OPT(1|2) that contain a COMPUTE or DIVIDE
  statement where the divisor is PIC 9(5) through 9(9) and has a
  value of 0, and is either COMP-5, or is COMP and TRUNC(BIN) is
  specified.
  
  RECOMMENDATION TO CUSTOMER: Apply the provided PTF
  
  PROBLEM SUMMARY: Binary divisions by powers of 2 can be changed
  to a right shift, which is better for performance. The compiler
  was making this change, for 32-bit BINARY data items, even when
  the divisor was 0, which replaced a division operation with a
  shift, avoiding the expected S0C9 abend.
  
  CONCLUSION: The compiler was fixed to not turn binary divisions
  into shifts when the divisor was 0.
  

Local fix

• Compile at OPT(0)
