IBM NPL Technical Report December 1964

This manual provides a detailed and comprehensive description of a new programming language, NPL. This new language is designed not only for applications programming in the traditional commercial andscientific fields, but also for programming in other applications areas. At the same time, the language is so designed that different levels oflanguage facility can be selected for given classes of applications or for given levels of programmer experience. The NPL Technical Report is only intended to describe the language and not to serve as a specification of the language for implementation by a particular compiler

This manual constitutes a description of NPL. It is a technical reportof NPL, not a student text, nor a user's guide for a particular compiler implementation of the language. Further publications describing the language are planned for a later date. In general, this manual assumes a relatively high level of programming knowledge and experience‘ on the part of the reader. Specifically, it assumesa thorough knowledge of modern programming concepts and techniques and some knowledge of current high-level programming languages. Accordingly, the manual is not intended for general distribution. The "Introduction" chapter provides the reader with a review of the designcriteria of NPL and a discussion of the more significant features of thelanguage; it also gives an indication of those parts of the manualthat are ofinterest to particular classes of users. The language description comprises the succeeding twenty-seven chapters. Various kinds of reference information have been organized into eight appendices, the last of which is concerned withimplementation of NPL for the IBM System/360. This description of NPL is based largely on reports issued by the SHARE Advanced Language Development Committee which included GUIDE representa- tion. IBM wishes to express its deep appreciation to that committee and toacknowledge the efforts of its members

We are extremely grateful to both Dawn and Kim Wakefield for the kind donation of the collection of their late father Richard Wakefield
