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

    The CREATE CLASS command establishes a class. After a class is
    created, you can place any related set of element generations
    in that class by using the INSERT GENERATION command. The CREATE
    CLASS command does not automatically place any generations in the
    created class.
