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)
