Book I, Power ISA User Instruction Set Architecture, covers the base instruction set and related facilities available to the application programmer. Book II, Power ISA Virtual Environment Architecture, defines the storage model and other instructions and facilities that enable the application programmer to cre- ate multithreaded programs and programs that interact with certain physical realities of the computing environ- ment. Book III, Power ISA Operating Environment Architec- ture, defines the supervisor instructions and related facilities. Anyway, I'm OK with either name. > > Thanks, > > C.
