JCL : JOB Control Language - Mainframe ZOS

Job Control Language (JCL) is a scripting language that describe jobs, to the Operating System that runs in the IBM large server (Mainframe) computers. JCL acts as an interface between your application programs (COBOL, PL/1 , Assembler etc) and Mainframe OS (MVS or Z/OS). It is mainly a set of control statements that provide the specifications necessary to run an application program. In mainframe environment, programs can be executed in batch and online modes. JCL is used for submitting a program for execution in batch mode.
