COBOL bug

The Question is:

How can I get the right line number from a COBOL
program for a Subscript out of range error in the
traceback. It looks like the compiler generates a GENTRAP
instruction, and then all the range checking code jumps
there to generate the crash.

The Answer is:

    Your analysis is correct. Thank you for bringing this issue to the
    attention of the COBOL engineering team. This problem has been logged
    into the problem tracking system used by COBOL engineering. A response
    will be posted here when the problem is resolved.

    In the meantime, be aware that more accurate traceback functionality
    is available with OpenVMS V7.0. Also, compiling the program /NOOPT
    should improve the behavior and reliability of the traceback
    information.

    We have fixed this problem.  The fix will be available in the next
    release of DEC COBOL (tentatively called V2.4).

    If you are interested in field testing DEC COBOL T2.4 to evaluate the
    fix, send mail to

    Thanks.
