/sys$common/syshlp/helplib.hlb CMS, CREATE, GROUP, Command Parameters  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 group-name

    Specifies a name for the group. CMS reports an error if you
    specify an existing group or class name. (Group and class names
    must be unique.) However, if a previously used group or class name
    has been removed with the DELETE GROUP or DELETE CLASS command,
    you can reuse that name with CREATE GROUP. A group name can also
    be a list of group names separated by commas. Wildcards are not
    allowed.

 remark

    Specifies a character string for the creation remark of the group
    to be logged in the history file with this command. The remark
    is enclosed in quotation marks. If no remark was entered, a null
    remark ("") is logged.
