/sys$common/syshlp/helplib.hlb SET, SECURITY, Parameter  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 object-name

    Specifies the name of an object, such as a file or device, whose
    security profile is to be modified. An object is identified by an
    object name and a class name. The default class name is FILE.

    An object name of the FILE class (explicitly or implicitly
    specified) can include an asterisk (*)  or a percent sign (%)
    wildcard character, but wildcard characters are not allowed
    in any class other than FILE. SET SECURITY does not operate on
    remote files and devices, alias directory entries, or directory
    names in UIC format (for example, [14,5]).

    The following table shows the qualifier categories for the SET
    SECURITY command.
