The reusable JCL collection consists of working samples of job control language (JCL) that new z/OS® professionals can copy, edit, and reuse to accomplish basic tasks on the job.

This collection is designed to help new users quickly become productive in the z/OS environment, while teaching JCL keywords and syntax within the context of realistic samples. The samples in the collection are based on tasks that existing z/OS customers have identified as most likely to be given to new z/OS professionals as part of their on-the-job training.

The samples in the reusable JCL collection are as complete as possible, and include line-by-line instructions and descriptions. Correctly modifying the samples for use, however, requires some basic knowledge of JCL techniques and of your own work environment. This collection includes a company checklist and other educational materials that can help you use the samples, and eventually code your own JCL.
