    /LOG
    /NOLOG (D)

    Controls whether MMS displays informational messages as it
    processes the description file. These qualifiers affect the
    behavior of MMS, but not the execution of action lines.

    The /LOG qualifier directs MMS to write all informational
    messages to your terminal screen while it processes the
    description file. The /LOG qualifier is useful for debugging
    your description files. These messages indicate what MMS finds
    and what it assumes as it processes the description file. You
    should include these messages with any MMS Software Performance
    Reports (SPRs) you submit. To save these messages in a file, type
    the following:

    $ DEFINE SYS$OUTPUT MYFILE.LOG
    $ MMS/LOG
       .
       .
       .
    $ DEASSIGN SYS$OUTPUT

    The /NOLOG qualifier prevents MMS from displaying informational
    messages. However, if you specify /NOLOG/CHECK_STATUS on the same
    command line, MMS does display the informational message that
    reports the value of MMS$STATUS. (See the description of the
    /CHECK_STATUS qualifier for more information about MMS$STATUS.)
