Log
    Nolog

    Specifies whether the processing of the command is reported to
    SYS$OUTPUT. Specify the Log qualifier to request that summary
    information about the resolve operation be reported to SYS$OUTPUT
    and the Nolog qualifier to prevent this reporting. If you specify
    neither, the default is the current setting of the DCL VERIFY
    flag. (The DCL SET VERIFY command controls the setting of the DCL
    VERIFY flag.)
