. .. NPL Technical Report. NPL Technical Report. 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 and scientific fields, but also for programming in other applications areas. At the same time, the language is so designed that different levels of language facility can be selected for given clas ses 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. December 1964 PREFACE This manual constitutes a description of NPL. It is a technical report of NPL, not a student text, nor a user's guide for a particular compiler implementation of the language. Furthe r publications de scribing the language are planned for a later date. In general, this manual assumes a relatively high level of programITling knowledge and experience on the part of the reader. Specifically, it aSSUITles a thorough knowledge of modern prograITlITling 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 design criteria of NPL and a discussion 'of the ITlore significant features of the language; it also gives an indication of those parts of the ITlanual'that are of interest to particular classes of users. The language description comprises the succeeding twenty-seven chapters. Various kinds of reference inforITlation have been organized into eight appendices, the last of which is concerned with impleITlentation of NPL for the IBM SysteITl/360. This description of NPL is based largely on reports issued by the SHARE Advanced Language DevelopITlent COITlITlittee which included GUIDE representa- tion. IBM wishes to express its deep appreciation to that cOITlmittee and to acknowledge the efforts of its ITleITlbers. This publication was prepared for production using an IBM computer tq, update the text and to control the page and line format. Page impressions for photo-offset printing were obtained from an IBM 1403 Printer using it special print chain.
