✦ Synopsis

"The great majority of books about machine language assume a considerable familiarity with both the details of microprocessor chips and with programming technique. This book assumes only a working knowledge of BASIC. It was designed to speak directly to the amateur programmer, the part-time computerist. It should help you make the transition from BASIC to machine language with relative ease." —From the Preface

Contains everything you need to learn 8502 machine language including:

· A dictionary of all major BASIC words and their machine language equivalents. This section contains many sample programs and illustrations of how all the familiar BASIC programming techniques are accomplished in machine language.

· The LADS assembler. A full-featured, commercial-quality, label-based programming language which supports 18 pseudo-ops, labels, multiple statements on a line, named variables, and remarks. Automatically switches between disk-based mode for large linked files or ultra-fast memory-based assembly mode. Automatic output to memory, screen, disk (1541 or 1571), or printer. (Cassette users must save the results via the built-in monitor.) Uses full 128 RAM, 2 MHz fast assembly, 40- or 80-column screen modes.

· Easy-to-understand descriptions of how you can make the best use of all the new features available on the 128.

· All 8502 commands fully explained and arranged for easy reference.

· Special chapters on the 128 programming environment and the expanded Kernal.

· Many clear, understandable examples and comparisons to already familiar BASIC programming methods.

· A library of frequently used subroutines.
