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
    VSI OpenVMS Guide to System Security.

    Rights identifiers are granted with the Authorize utility and
    use an ID format rather than a UIC format. For more information
    about rights identifiers, see the VSI OpenVMS Programming Concepts
    Manual.

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