VMS Help CREATE, /NAME_TABLE, Qualifiers, /LOG  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /LOG (default)
       /NOLOG

    Controls whether an informational message is generated when
    the SUPERSEDE attribute is specified, or when the table already
    exists but the SUPERSEDE attribute is not specified. The default
    is the /LOG qualifier; that is, the informational message is
    displayed.
