I just worked on a problem where an old out-of-service version of an OS on z/VM on a z10 worked in one shop, and not in another. And, get this, the error was the 'operand exception' kind. If it isn't "supported" then we have not run the OS through its paces and examined any requirements or restrictions. It may work or it may not. People who say it won't work are probably aware of certain configurations where it won't, in fact, work. Those who say it WILL work haven't talked to the nay-sayers. :-) Alan Altmark z/VM Development IBM ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
