PMDF CRDB/DUMP is a synonym for PMDF DUMPDB. It is used to cause
    PMDF CRDB to dump an existing database to a flat text file-or
    to SYS$OUTPUT if no output file is specified. When /DUMP is
    specified, the parameters to PMDF CRDB are interpreted as the
    input database specification, and optionally a flat text file
    to which to write the output. No other qualifiers are valid when
    /DUMP is specified.
