Nolog

    Logs the creation of a binary statistics file to your output
    file. This binary statistics file is created only if you have
    used the Output qualifier. If you use the Nolog qualifier, no
    operations will be logged to your output file.

    The default is the current setting of the DCL verify switch. See
    HELP SET VERIFY in DCL HELP for more information on changing the
    DCL verify switch.

    If you use the Interactive qualifier, the Log qualifier is
    ignored.
