Job Control Language

Job Control Language (JCL) is a scripting language used on IBM mainframe operating systems to instruct the system on how to run batch jobs. JCL is composed of control statements that define the input, output, and processing resources required for each job step. These statements are used to allocate files and devices, as well as specify programs or utilities that are executed by the job steps. The script-like nature of JCL allows for conditional execution based on previous step completions or error conditions. It has traditionally been associated with older mainframe technologies but continues to be a significant part of many enterprise computing environments due to large organizations' reliance on legacy applications and data stored on mainframes.
