Any program on the 20 uses paging, whether it knows it or not. I don't think that constricts the programmer as RMS implies, nor is it terribly slow. It turns out that the system demand pager is not nearly as smart as the editor in determining what to page, as you will realize after considering what happens on two consecutive searches through an entire buffer that does not fit in physical memory.

So the question is not whether disk paging should be done, but rather who should do it. I think RMS will agree that if ITS TECO provided a virtual buffer space that was larger than the 20's address space and whose paging was invisible at the level of TECO code, there would be no serious impact on user-written extensions. -------
