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.
