An engine is of course an engine. Clean delegability/delegation is another matter. Work must be done and has been done to achieve them. In other words, while the motivation for the introduction of zIIPs was certainly a marketing one, programming support had to be provided for their use; I expect to see them or something substantively very like them reappear under z/TPF. Mr Tomlin does not. z/TPF is unusual in that it is not a fully autonomous, independently usable operating system. SYSGENs and the like for it must, for example, be done under z/OS. In my experience situations of this sort give rise to customer pressures to make things usable in both environments, for all the obvious reasons. I did, however, attempt to make it clear that what I said was conjectural. I have no arcane knowledge of IBM's plans for z/TPF. Mr Tomlin is entitled to make his guesses as I made mine, he has done so; and I am unrepentent about our differences.
