This book describes 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. To perform the tasks, programmers code job control statements. This book describes how to use 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 designed as a user’s guide, to be used when deciding how to perform job control tasks. It does not describe how to code the statements. For an introduction to the statements and for coding information, see the companion book, z/OS MVS JCL Reference.
