That's a very good clarification of the relationship between N and N3. Thank you.

An 'N3' instruction is implicitly an 'N' instruction.

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 This message and any attachments are intended only for the use of the addressee and may contain information that is privileged and confidential.
