If z/OS doesn't fit a traditional CS definition of a kernel, then what is it? Does the BCP act as a micro or nano kernel with all other services sharing its address space? Does the concept of "rings" or "kernel address space" even exist on these machines?

Well, historically IBM has used the term OS to include everything bundled with the system. >Especially since z/OS comes also with a UNIX kernel. Which isn't a kernel in the sense that the CS mean. In fact, it would be hard to find a part of MVS that qualified as a "kernel"; it really doesn't fit that model. -- Shmuel (Seymour J.)
