Publisher's Synopsis
A highly successful and proven method of learning MVS internals through the use of working examples. This guide provides the reader with all the tools necessary to understand and utilize the internal services of MVS by implementing the same methods that the operating system itself uses. The examples in the book are complete programs, including the JCL uses. and control statements for compiling, link-editing and executing the code. The book describes the major components of MVS, explains the workings of each component in detail, and provides clearcut explanations and examples of the new ESA features of MVS, including access register addressing mode, dataspaces, hyperspaces and the linkage stack.
