VMS Help CMS, SET, ACL, Command Parameters  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 object-expression

    Specifies one or more objects whose ACL is to be modified.
    Wildcards and a comma list are allowed.

    The object name depends on the object type (see the /OBJECT_TYPE
    qualifier). For example, if the object type is CLASS, the object
    name is the name of a class in the CMS library. The same principle
    applies to elements and groups. If the object type is LIBRARY, the
    object expression must be a list of one or more of the following
    keywords:

       ELEMENT_LIST
       CLASS_LIST
       GROUP_LIST
       HISTORY
       LIBRARY_ATTRIBUTES

    These keywords are referred to as object subtypes. You can
    abbreviate object subtypes. Wildcards are not allowed.

    The object name can also be the name of a CMS command. If /OBJECT_
    TYPE is specified as COMMAND, SET ACL modifies the ACL on the
    given command. Commands that contain two words must be specified
    with an underscore, for example, INSERT_ELEMENT.

 remark

    Specifies a character string to be logged in the history file
    with this command, usually used to explain why the command was
    entered. The remark is enclosed in quotation marks. If no remark
    was entered, a null remark ("") is logged.
