Job Control Language, usually abbreviated JCL, is a name for scripting languages used on IBM mainframe operating systems to instruct the system how to run a batch job or start a subsystem. Its purpose is to say which programs to run, which files or devices to use for input and output, and at times under what conditions to skip a step. There are two distinct IBM Job Control languages: one for the operating system lineage that begins with DOS/360 and whose latest member is z/VSE, and one for the lineage from OS/360 to z/OS, which now includes the JES extensions and Job Entry Control Language. The Programming Language Database dates JCL to 1964 and names IBM as the place of its early development.
