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

       /OWNER_UIC=option

    Requires SYSPRV (system privilege) privilege for a user
    identification code (UIC) other than your own.

    Specifies the owner UIC for the directory. The default is your
    UIC. You can specify the keyword PARENT in place of a UIC to mean
    the UIC of the parent (next-higher-level) directory. If a user
    with privileges creates a subdirectory, by default, the owner
    of the subdirectory will be the owner of the parent directory
    (or the owner of the MFD, if creating a main level directory).
    If you do not specifiy the /OWNER_UIC qualifier when creating a
    directory, the command assigns ownership as follows: (1)  if you
    specify the directory name in either alphanumeric or subdirectory
    format, the default is your UIC (unless you are privileged, in
    which case the UIC defaults to the parent directory); (2)  if you
    specify the directory in UIC format, the default is the specified
    UIC.

    Specify the UIC by using standard UIC format as described in the
    OpenVMS User's Manual.
