Specious argument: pages are in shared core at any time as well, but that's a different argument. AFAIK, CP paging decisions are not directly accessible inside a guest in any programmatic form (other than generating bad behavior to get yourself paged out, which is counterproductive if you're trying to intercept things), whereas spool access is fairly easy. That's why I said "some good arguments". Never claimed it to be exhaustive, or definitive. > > (VSE is so much better behaved as a VM guest.

You can't ask the support people to change something that doesn't exist in the product -- that triggers the "function not in product" response and the PMR gets closed SUGG (which pretty much is a black hole, viewed externally). Unless its changed recently, there's nothing equivalent to the simple ",VM" option that VSE has for UR devices. That takes us into the realm of requirements, and we've been there recently. AFAIK, JES development has rejected this requirement 8 times that I'm aware of in the last 27 years. At some point, one takes "no" at face value, and goes back to coding the JES mods needed to get the job done. -- db ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
