Ref: Your note of Wed, 27 Aug 2014 13:57:13 +0000 Look at the manual sections called "Using Access Registers", which can also be found via Google.
There's an introductory section in "z/OS MVS Programming: Assembler Services Guide", and more details in "z/OS MVS Programming: Extended Addressability Guide". From a hardware architecture point of view, you can find more about how it works in "z/Architecture Principles of Operation".
