Description

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.
