JCL Command Quick Reference.

Job Control Language (JCL) is used to tell the system what program to execute, followed by a description of program inputs and outputs. It is possible to submit JCL for batch processing or start a JCL procedure (PROC), which is considered a started task.

The details of JCL can be complicated but the general concepts are quite simple. Also, a small subset of JCL accounts for at least 90% of what is actually used.

Job control language (JCL) is a set of statements that you code to tell the z/OS® operating system about the work you want it to perform.
