This book lists the job control tasks needed to enter jobs into the operating system, control the system's processing of jobs, and request the resources needed to run jobs. This book also contains a chapter that describes started tasks and how to set them up. To perform these tasks, programmers code job control statements. This book describes how to code these statements, which consist of:
- Job control language (JCL) statements
- Job entry subsystem 2 (JES2) control statements
- Job entry subsystem 3 (JES3) control statements.
This book is needed by system and application programmers who enter programs into the operating system. Those using this book should understand the concepts of job management and data management.
