John, I don't think you understand zIIPs and zAAPs. There is NO hardware difference between zIIPs, zAAPs, GPs or any other engine (IFL, ICF, SAP - have I left out any?). The difference is the work marked for dispatch on them.

At least from an application viewpoint. I wish that I had one so that I could "fiddle around" to see what would fail. I am very confident that all "general purpose" (user mode) instructions are fully supported. But perhaps not all of the privileged instructions. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
