Control Program Facility (CPF) is the operating system of the IBM System/38. [3] CPF represented an independendent line of development at IBM Rochester, and was unrelated to the earlier and more widely used System Support Program operating system.

CP/M, [3] originally standing for Control Program/Monitor [4] and later Control Program for Microcomputers, [5] [6] [7] is a mass-market operating system created in 1974 for Intel 8080/85-based microcomputers by Gary Kildall of Digital Research, Inc. CP/M is a disk operating system [8] and its purpose is to organize files on a magnetic storage medium, and to load and run programs stored on a disk.
The operating system provides an interface between an application program and the computer hardware, so that an application program can interact with the hardware only by obeying rules and procedures programmed into the operating system. The operating system is also a set of services which simplify development and execution of application programs.
In 1961, the MCP was the first OS written exclusively in a high-level language (HLL). The Burroughs Large System (B5000 [2] and successors) were unique in that they were designed with the expectation that all software, including system software, would be written in an HLL rather than in assembly language, which was a unique and innovative approach in 1961.
IBM Airline Control Program, or ACP, is a discontinued operating system developed by IBM beginning about 1965. In contrast to previous airline transaction processing systems , the most notable aspect of ACP is that it was designed to run on most models of the IBM System/360 mainframe computer family.
