/LOG
       /NOLOG (default)

    Controls whether a termination message is displayed at the
    terminal after successful completion of the DSR operation. The
    message states the DSR version number, the number of diagnostic
    messages (if any), the number of output pages, and the output
    file specification.

    If you specify the /INTERMEDIATE qualifier, the message also
    includes the number of index records produced and the number of
    table of contents records produced.

    If there are errors in processing, DSR displays a message on the
    terminal even if the /NOLOG qualifier is specified.
