Control Program

The Control Program provides the basic functions of OS/2, including DOS emulation and the support for keyboard, mouse, and video input/output.

The lowest-level functions supplied by OS/2 are those provided by the kernel and the kernel's subsystems - the control programs of the operating system. The Control Program Functions involve the most basic aspects of program execution, such as memory management, file handling, and process, thread, and session management. They also involve more sophisticated programming tasks, such as exception handling and interprocess communications.
