I think we may mean different things by the word "window" which in 1974 could not refer to little boxes on bitmapped screens (as there weren't any!). I remember the "window" being the height of the letterbox through which we peered at our source files on text-only glass teletypes, so "z" let you change the height of that letterbox. I don't have the source of the original Berkeley ed any more, but the original ex, which extends ed, behaves in the same way as the newly-corrected GNU ed, i.e. z10 prints 10 lines. And the "10" is not persistent to following "z"'s. Hope this helps.
