VMS Help CMS, ACCEPT, GENERATION, Qualifiers, /GENERATION[=generation-expression]  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Specifies a particular generation of the element to be accepted.
    If you omit /GENERATION, CMS accepts the most recently created
    generation with a review pending. You specify this qualifier only
    if more than one generation of an element is under review.
