Job Control Language (JCL) is a crucial command language used in IBM Mainframe computers. It helps identify the program to be executed, specifies necessary inputs, and communicates with the Operating System through Job Control Statements. In the mainframe environment, programs can be executed in both batch and online modes. JCL is primarily used for submitting programs for batch execution.

JCL acts as a scripting language to interact with the MVS operating system, enabling us to run jobs efficiently. It allows us to perform a sequence of tasks divided into various statements and parameters. Even a COBOL program relies on JCL for execution. JCL provides essential information such as file names, file locations, associated file names, compiled module locations, statements, parameters, and much more.
