:-) I think you'll find that z/VM, z/OS, and z/VSE all currently share the same Architectural Level Set (ALS). The ALS defines the lowest level of processor that the operating system will support (run on). Right now, we all have z/Architecture as the only requirement. While we can (and do) exploit the latest & greatest, we must tolerate a system as old as z900. Alan Altmark z/VM Development IBM Endicott
