IBM System/370 Systems Principles of Operation The IBM System/370 is a data processing system that is based on the IBM System/360 but that extends the capabilities of that system. This manual describes extensions to the functional design of the System/360 that are incorporated in models of the System/370. The reader is assumed to have an understanding of the System/360, as described in the IBM System/360 Principles of Operation, GA22-6821. The System/370 Princples of Operation should be used in conjunction with the System/360 Principles of Operation. For information about the characteristics, functions, and features of a specific System/370 model, use the functional characteristics manual for that model. Preface Just as the IBM System/360 Principles of Operation is the machine reference manual for the IBM System/360, this publication is the machine reference manual for the IBM System/370. It deals, however, only with those functions that are additional to or different from those of the System/360, and the reader therefore must rely directly on the IBM System/360 Principles of Operation., GA22-6821 Note that this publication is not written as an introduc- tion or as a textbook but as a reference document. Other manuals are available that serve those other functions. It assumes the reader has a basic knowledge of data processing systems and, specifically, the IBM System/360. Such basic information can be found, for example, in the Introduction to IBM Data Processing Systems, GC20-1684, and in the IBM System/360 System Summary, GA22-6810. The information in this manual is aimed most directly at those readers concerned with the preparation of programs to be run on the System/370, where in such preparation a knowledge of the machine language and system functions is pertinent. At the same time, the book contains information that may be of particular interest to system designers.
