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

       /OWNER
       /NOOWNER (default)

    Controls whether the file owner's user identification code (UIC)
    is listed.

    The default size of the owner field is 20 characters. If the
    file owner's UIC exceeds the length of the owner field, the
    information will be truncated. The size of this field can be
    altered by specifying /WIDTH=OWNER, along with a value for the
    owner field. For more information, see the description of the
    /WIDTH qualifier.
