    Specifies the user identification code (UIC) or rights identifier
    for which the quota entry is added. You can specify the UIC in
    numeric or alphanumeric format. For complete information about
    UIC specification, refer to the OpenVMS Guide to System Security.

    Rights identifiers are granted with the Authorize utility and
    use an ID format rather than a UIC format. Refer to the OpenVMS
    Programming Concepts Manual for a complete description of rights
    identifiers.

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