owner

    Specifies the user identification code (UIC) or rights
    identifier. You can specify the UIC in numeric or alphanumeric
    format. For complete information about UIC specification, see the
    HP OpenVMS Guide to System Security.

    Rights identifiers are granted with the Authorize utility and use
    an ID format rather than a UIC format. For a complete description
    of rights identifiers, see the HP OpenVMS Programming Concepts
    Manual.

    When working in nonlocal environments, make sure that the
    alphanumeric UIC or rights identifiers that you use are valid
    for the environment.
