For students of systems programming, this book provides a pragmatic and practically orientated course in programming language translation. Using standard Pascal throughout, students are encouraged to explore areas of language design and implementation through carefully integrated practical work. Complete case studies, suitable for use on small systems, serve as a foundation and provide a stimulating challenge in the many projects and exercises that are suggested.

Teaches Concepts for the User Seeking an Understanding of the Functions Needed to "Translate" Programs for Computer Execution

“This book provides an introduction to some of the more important techniques used in the construction of program translators” -- Preface.

A new edition of a textbook that provides students with a deep, working understanding of the essential concepts of programming languages, completely revised, with significant new material. This book provides students with a deep, working understanding of the essential concepts of programming languages. Most of these essentials relate to the semantics, or meaning, of program elements, and the text uses interpreters (short programs that directly analyze an abstract representation of the program text) to express the semantics of many essential language elements in a way that is both clear and executable. The approach is both analytical and hands-on. The book provides views of programming languages using widely varying levels of abstraction, maintaining a clear connection between the high-level and low-level views. Exercises are a vital part of the text and are scattered throughout; the text explains the key concepts, and the exercises explore alternative designs and other issues. The complete Scheme code for all the interpreters and analyzers in the book can be found online through The MIT Press web site. For this new edition, each chapter has been revised and many new exercises have been added. Significant additions have been made to the text, including completely new chapters on modules and continuation-passing style. Essentials of Programming Languages can be used for both graduate and undergraduate courses, and for continuing education courses for programmers.

An Essential Reference for Intermediate and Advanced R Programmers Advanced R presents useful tools and techniques for attacking many types of R programming problems, helping you avoid mistakes and dead ends. With more than ten years of experience programming in R, the author illustrates the elegance, beauty, and flexibility at the heart of R. The book develops the necessary skills to produce quality code that can be used in a variety of circumstances. You will learn: The fundamentals of R, including standard data types and functions Functional programming as a useful framework for solving wide classes of problems The positives and negatives of metaprogramming How to write fast, memory-efficient code This book not only helps current R users become R programmers but also shows existing programmers what’s special about R. Intermediate R programmers can dive deeper into R and learn new strategies for solving diverse problems while programmers from other languages can learn the details of R and understand why R works the way it does.

Formal procedures are summarized for constructing translators whereby a computer is used to generate substantial portions of the translators, the latter being termed symbolic machine language assemblers, macro expanders, or compilers. The translators all perform the task of translating programs written in one language into equivalent programs written in another. BASIC BOOTSTRAP PROCEDURE: The first translators were written in an available machine language and were mostly symbolic machine language translators (assemblers). Application of the 'bootstrap' procedure was the writing in symbolic language, including the translator itself, of programs, once a symbolic machine language translator became available for a particular machine. The bootstrap procedure has the property that each translator can translate its own description into itself since it is described by a language which is a subset of the language it translates. The NELIAC, compiler for the Remington Rand M460 is a 'selfcompiling compiler'. MULTIPLE BOOTSTRAP PROCEDURES: These procedures involve translators producing object programs for machines other than the machine that performed the translation. As an example of the use of an intermediate language and multiple bootstrap procedure, there is cited the translator constructed for the FORTRAN language and the IBM-7090 and CDC-3600 computers by Mendicino, Storch, and Sutherland at the Lawrence Radiation Lab. of the University of California.
