So all the VM Assist instructions are gone? Wow! Later, Steve Thompson

Everything else is virtualization or simulation of real z/Architecture and processor-specific facilities. Other than that, there are no "special instructions" in VM. CP uses the Interpretive Execution Facility (the SIE instruction) just like PR/SM does to create partitions - the hardware is sophisticated enough to allow both to run at the same time. And while PR/SM and CP share a common ancestor, the cybergenetic drift is such that they are no longer recognizably similar, having evolved to play very different roles in the arena of virtualization. <snip> ---------------------------------------------------------------------- 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
