/OUTPUT[=filespec]

    Requires READ and WRITE access to the directory in which the
    output file is to be created.

    Specifies where the output from the DUMP command is sent. If you
    omit this qualifier, output is sent to the current SYS$OUTPUT
    device (usually your terminal). To send the output to a file, use
    the /OUTPUT qualifier. If you do not supply a file specification,
    the output is sent to the file LMCP_DUMP.LIS in your default
    directory.
