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. Although this set of statements is quite large, most jobs can be run using a very small subset. Learn about essential and most frequently used JCL statements and parameters, as well as coding techniques.

JCL statements tell z/OS where to find the appropriate input, how to process that input (that is, what program or programs to run), and what to do with the resulting output.
