Alan / David / Adam, Thanks for your responses - it would seem that my understanding of the
rules is not at odds with yours and that such a strategy is at least acceptable from a legal / contractural standpoint. Support of old DASD geometries was my specific thought - but I love the idea of, "doing" a 64-bit system under a 31-bit system via Hercules - hig h on cough-syrup indeed! Your responses leave me with the comfortable feeling that, should the nee d ever arise, I do at least have some kind of, "Plan B" to entertain. Regards Jeff
