VMS Help CMS, SHOW, GENERATION, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The SHOW GENERATION command lists information about a specific
    generation of an element or a group of elements. By default, this
    command displays the transaction record of the latest generation
    on the main line of descent. You can also use SHOW GENERATION
    to display the element name and generation number of all element
    generations belonging to a specified group or class.
