VMS Help CMS, SHOW, ACL, Qualifiers, /OBJECT_TYPE=type  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Specifies the type of the object whose ACL is to be displayed.
    There is no default object type; therefore, this qualifier is
    required. The object type can be one of the following keywords:

       ELEMENT
       CLASS
       GROUP
       LIBRARY
       COMMAND
