Control Lanuage programs have been the operational interface between the operating system and application programs from the IBM System/38 to the AS/400, to the iSeries, and the current power systems architecture.

Control Language (CL) is the user interface to the OS on the IBM Power i Platform. Many CL commands may be executed from a command line. Some are restricted to a Control Language Program (CLP). Therein lies the power of CL, it can be used to create application programs as well as modules and service programs. Over the years, IBM has added new functions to CL to make it a solid tool for system work management, job scheduling, and even application development.

It has the added benefit of being able to message individual users, a group of users, or to communicate with SYSOPR, the default system operator profile, with simple commands.
