Jaffe | | Depends on what you mean by a "real" difference. z/OS uses at least one instruction which is not implemented on an IFL as it is on a GP processor. That's why you will get a "check stop" condition if you IPL z/OS in an LPAR which is defined as using an IFL. I agree that a problem program should see no differences. I was always curious if I could figure out a way to "cheat" to run COBOL on a zAAP somehow. But I don't have a zAAP to mess around with. And I don't run z/OS 1.7 either (isn't that were zAAPs are first supported?) But I will admit that I don't know exactly how different a zAAP is from a GCP. I just remember that some things will NOT work on a zAAP. I thought it was supervisory instructions and some types of interrupts. -- John McKown Senior Systems Programmer UICI Insurance Center Information Technology This message (including any attachments) contains confidential information intended for a specific individual and purpose, and its content is protected by law.
