It’s only job is to emulate hardware and manage resources. • Does not provide file editing or writing capabilities. It can read CMS files for use with system configuration. • Cannot compile, assemble or execute programs. • CMS started out as an operating system during the early days of mainframes. • Became popular as a “guest” on CP to provide user/application functions.

    The IBM System/38

    8 The IBM System/38 8.1 Introduction IBM’s capability-based System38 [Berstis 80a, Houdek 81, IBM Sa, IBM 82b], announced in 1978 and delivered in 1980, is an outgrowth of work that began in the late sixties and early seventies on IBM’s future system (FS) project. Designers at the IBM Development Laboratory in Rochester, Minnesota incorporated ideas from FS, modified by their needs, to pro- duce a system for the commercial marketplace. It is interesting that such an advanced, object-based architecture has been ap- plied to a very traditional product space. Initially, only the COBOL and RPG III languages were provided. The system, which includes the CPF (Control Program Facility) operating system, is intended to support transaction processing and data- base applications constructed in commercial languages. A major goal of the System38 design is to maintain pro- grammer independence from the system implementation [Dahlby SO]; IBM wished to retain maximum flexibility to modify System38’s implementation for future technologies while supporting previously written System38 programs. The designers also wished to support a high level of integrity and security at the machine interface and to support commonly executed user and system functions efficiently, such as data- base searches and memory management [Hoffman 801. To meet these goals, IBM chose a layered machine structure with a high-level programming interface. The layers of this design are shown in Figure 8-l. At the lowest level is a hardware machine that directly exe- 137 The IBM System/38 User Applications Verticai Microcode Horizon&/ Microcode Hardware Machine Figure 8-1: System/38 Implementation Layers cutes 32-bit horizontal microcode.
