Ideally, I would like to create all future data spaces with a size of 2GB, rather than 2GB OR 2GB-4K (when the returned ORIGIN value is NZ). I looked at assembler service reference manuals as far back as 1999, and they all state that a non-zero origin value (4K) is based on a processor dependency. I eventually found a vintage IBM-Amdahl presentation (1989) indicating the dependency is due to low-address protection being in effect when the PSF (Private-Space Facility) is not active.
My question is... Is this still relevant 30 years later? Do any G10 or above customers run configurations where PSF is inactive?
