JCL (Job Control Language)

Job Control Language (JCL) is a specialized scripting language used in mainframe computing to instruct the system on how to run specific tasks or jobs. It acts like a detailed set of instructions, specifying things such as what programs to execute, what data to use, and how to handle outputs. Essentially, JCL automates and manages complex processing steps behind the scenes, ensuring that tasks are carried out correctly and efficiently without manual intervention. It’s an essential tool for organizations relying on mainframe systems to handle large-scale, automated data processing.
