Dragon Machine Language for the Absolute Beginner


Book Description

First published in 1983, this easy-to-follow guide to using machine language on the Dragon 32 gave users an excellent insight into the acclaimed machine that many considered well ahead of its time. Though it was more powerful and quicker than many of its competitors, the Dragon 32 never gained the success of other 8-bit computers of the day such as the Commodore 64 or the ZX Spectrum. Despite this, the classic machine still retains a dedicated following to this day. Not only is this remastered version perfect for hobbyists and collectors, it is also a highly useful resource for those interested in programming retro games and utilities. * * * As the original publisher Melbourne House wrote: Write faster, more powerful space saving programs for your Dragon. Written exclusively for Dragon users, Dragon Machine Language for the Absolute Beginner offers a complete instruction course in 6809 Machine Language, with particular reference to the Dragon 32. Even with no previous experience of computer languages, the easy-to-understand 'no jargon' format of this book will enable you to discover the power of the Dragon's own language. After introducing you to machine language and the 6809 instruction set, the book provides you with a series of short test programs which are designed to demonstrate all the Dragon's machine language instructions. These programs illustrate the use of the various instructions, their effects and actions, and will enable you to gain a practical understanding of machine language. You are encouraged to develop routines with all the instructions in order to become familiar with the 6809's instructions as well as gaining experience in writing short machine language routines. In addition to learning machine language, there are sample programs designed to demonstrate the power and potential of machine language in extracting the most from your Dragon. You will find that these programs contain routines that you can use when writing your own programs. In logical steps the book takes you through a comprehensive course in machine language, including understanding assembly language, designing and writing your own programs and a thorough grounding in the purpose and use of each of the instructions in the 6809 Instruction Set. * * * Acorn Books is proud to present its Retro Reproductions series, a collection of classic computing works from the 80s and 90s given a new lease of life in the 21st century. From standards of programming reference no self-respecting microcomputer coder would be without, to obscure works unavailable for many years, these modern re-prints are perfect for any connoisseur of retro computing.

The Dragon 32 Programmer's Reference Guide will show you how to exercise the full potential of your Dragon 32, by taking you from simple BASIC routines right through to advanced machine language programs. The book fully examines BASIC and tells you everything you need to know to use every function to its maximum. Each facility is illustrated by example programs. Many professional hints and tips are included, demonstrating the full features of the Dragon 32, especially the graphics and sound potential. For the serious programmer, a memory map is included as well as 'monitor entry points' giving more information about the Dragon 32 than has ever been published anywhere else. This book will take you far beyond the realms of standard Dragon 32 programming. ***** Acorn Books is proud to present its Retro Reproductions series, a collection of classic computing works from the 80s and 90s given a new lease of life in the 21st century.

Crafting Interpreters


Book Description

Despite using them every day, most software engineers know little about how programming languages are designed and implemented. For many, their only experience with that corner of computer science was a terrifying "compilers" class that they suffered through in undergrad and tried to blot from their memory as soon as they had scribbled their last NFA to DFA conversion on the final exam. That fearsome reputation belies a field that is rich with useful techniques and not so difficult as some of its practitioners might have you believe. A better understanding of how programming languages are built will make you a stronger software engineer and teach you concepts and data structures you'll use the rest of your coding days. You might even have fun. This book teaches you everything you need to know to implement a full-featured, efficient scripting language. You'll learn both high-level concepts around parsing and semantics and gritty details like bytecode representation and garbage collection. Your brain will light up with new ideas, and your hands will get dirty and calloused. Starting from main(), you will build a language that features rich syntax, dynamic typing, garbage collection, lexical scope, first-class functions, closures, classes, and inheritance. All packed into a few thousand lines of clean, fast code that you thoroughly understand because you wrote each one yourself.







How to Design Programs, second edition


Book Description

A completely revised edition, offering new design recipes for interactive programs and support for images as plain values, testing, event-driven programming, and even distributed programming. This introduction to programming places computer science at the core of a liberal arts education. Unlike other introductory books, it focuses on the program design process, presenting program design guidelines that show the reader how to analyze a problem statement, how to formulate concise goals, how to make up examples, how to develop an outline of the solution, how to finish the program, and how to test it. Because learning to design programs is about the study of principles and the acquisition of transferable skills, the text does not use an off-the-shelf industrial language but presents a tailor-made teaching language. For the same reason, it offers DrRacket, a programming environment for novices that supports playful, feedback-oriented learning. The environment grows with readers as they master the material in the book until it supports a full-fledged language for the whole spectrum of programming tasks. This second edition has been completely revised. While the book continues to teach a systematic approach to program design, the second edition introduces different design recipes for interactive programs with graphical interfaces and batch programs. It also enriches its design recipes for functions with numerous new hints. Finally, the teaching languages and their IDE now come with support for images as plain values, testing, event-driven programming, and even distributed programming.




The Iron Dragon's Daughter


Book Description

A New York Times Notable Book: “Combining cyberpunk’s grit with dystopic fantasy, this iconoclastic hybrid is a standout piece of storytelling” (Library Journal). Jane is trapped as a changeling in an industrialized Faerie ruled by aristocratic high elves and populated by ogres, dwarves, night-gaunts, and hags. She is the only human in a factory where underage forced labor builds cybernetic, magical dragons that are weaponized and sent off to war. When the damaged dragon Melanchthon tempts Jane with promises of freedom, the stage is set for a daring escape that will shake the foundations of existence. Combining alchemy and technology, a coming-of-age story like no other, The Iron Dragon’s Daughter takes place against a dystopic mindscape of dark challenges and class struggles that force Jane to make costly decisions at every turn. A finalist for the Arthur C. Clarke Award, the World Fantasy Award for Best Novel, and the 1994 Locus Award, The Iron Dragon’s Daughter a is one-of-a-kind melding of grimdark fantasy and cyberpunk grit from the Nebula Award–winning author of Stations of the Tide. It engages the reader in a nihilistic world in which nothing is as it seems and everything comes at a steep and often horrific price.
