✦ Synopsis

Assembly language programming is the key to writing faster, more sophisticated programs that tap the full power of your microcomputer. This dynamic guide shows you how to put the powerandefficiency of this programming tool—previously available only to professionals—to work for you. The formatis self-paced and self-instructional, and the crystalclear coverage is equally applicable to Apple®, Atari®, and Commodore microcomputers—in fact to any machine based on the 6502 microprocessorchip.

From a discussion of the characteristics and features of 6502 Assembly Language,the authors take you step by step through the entire set of assembly language instructions. You'll get hundreds of opportunities to practice coding typical routines and to check and correct your errors. You'll master techniques for handling routine operations, conditional commands, assembly language logic, subroutines, numeric manipulation, and more.

Scores of sample programs demonstrate how the instructions are used in practice. Abundant summaries and self-tests reinforce the material every step of the way. And, because the book requires only minimal knowledge of programming, even computer novices can easily add the fundamentals of assembly language to their repertoire.
