And I'd almost bet that the generations are stored as a full member. That is, not compressed (unless the DSN itself is compressed) and not a "delta deck". Personally, I'd probably only allow it for something like control card library. We use CA-Endevor, so we have what we need for most things. The only group which doesn't use CA-Endevor is ... us. But it is somewhat nice.
