The ABCs of z/OS System Programming is a eleven volume collection that provides an introduction to the z/OS operating system and the hardware architecture. Whether you are a beginner or an experienced system programmer, the ABCs collection provides the information that you need to start your research into z/OS and related subjects. If you would like to become more familiar with z/OS in your current environment, or if you are evaluating platforms to consolidate your e-business applications, the ABCs collection will serve as a powerful technical tool. This volume describes the basic system programming activities related to implementing and maintaining the z/OS installation, and provides details about the modules used to manage jobs and data. The topics covered are: Overview of the parmlib definitions and the IPL process. The parameters and system data sets necessary to IPL and run a z/OS operating system are described, along with the main daily tasks for maximizing performance of the z/OS system. Basic concepts related to subsystems, how to use the subsystem services provided by IBM subsystems, and planning considerations for setting up and writing your own subsystem. Job management in the z/OS system using the job entry subsystems JES2 and JES3. Detailed discussion of how JES2 and JES3 are used to receive jobs into the operating system, schedule them for processing by z/OS, and control their output processing. The link pack area (LPA), LNKLST, authorized libraries, and the role of VLF and LLA components. SMP/E Language Environment
