Folks, I am looking at the Principles of Operation telling me the ML and MLR that are flagged N3 in the summary. And the legend says:
"N3 Instruction is new in z/Architecture and has been added to ESA/390. Any RSY or RXY instructions still use the RSE or RXE format and 12-bit displacements in ESA/390." Wonder about the "has been added" - does this mean that 9672 machines had it added with a then-current MLC upgrade, or is it available for ESA/390 LPAR on a zArchitecture machine. Would it have to be in the OPTABLE(ESA) then? Rob
