MVS Control Blocks

This work is a highly technical treatment of the internal logic of IBM's MVS mainframe operating system. Seasoned system programmers who desire a very detailed reference should find it useful in fine tuning, troubleshooting/problem determination and systems software development. Based on the real-world needs of MVS programmers, the book identifies techniques, using MVS data areas, of extracting information about the programmer's environment. Diagrams and illustrations are also included.
