Sure, but we're back to the "licences vs MIPS" issue. No one denies that shipped (and presumably installed) MIPS goes up every year, but the number of processors running z/OS or VM is surely way down from what it was. Think of all those places that ran PROFS and a few CMS apps for "convenience computing" in the early 1990s. Many big companies had a little 43x1 in each major branch office for that, all hooked together with RSCS and PVM and not much else. Remember the 9370 - the "Vax killer"? Remember the Information Centre? All that stuff is gone. The small companies that used to run that stuff aren't on any kind of mainframes any more. The large organizations certainly are, but on far fewer images, and far more centralized. Well, of course I don't have access to IBM's numbers, so I may be full of it. But this is my impression. Maybe you can tell us if VM still has 20,000 licences out there...
