Control Program Facility: Programming languages, Data storage & Capability-based addressing

Control Program Facility (CPF) is the operating system of the IBM System/38. CPF represented an independent line of development at IBM Rochester, and was unrelated to the earlier and more widely used System Support Program operating system. CPF evolved into the OS/400 operating system, which was originally known as XPF (Extended CPF).
