Why do you need windowing? What you need is to mage the pages, and the same issues exist whether the mapping is windowed or direct into virtual memory.

How would it help here? The discussion has been (mostly) about loading an entire dataset into virtual storage (as ISPF Edit does) vs windowing techniques that avoid requiring a huge amount of virtual. I wasn't suggesting that DIV could apply directly to (say) a PS or PO dataset, but if you want to implement windowing you need some scheme to map file data to a smaller amount of virtual storage. DIV would seem to be a base to build on.
