Top-down assembly language programming for your VIC-20 and Commodore 64

Now you can learn about assembly language from the top down! Learn
how It works and how to make it work for you. This book, for V1C-20™
and Commodore 64™ computer owners who know little or nothing
about bits, bytes, hardware, and software, presents a guided tour of
your computer. Beginning with basic concepts such as what is
memory? and what is a program?, Top-Down Assembly Language
moves through a fast but surprisingly complete course in assembly
language programming. Having mastered these fundamentals, the
reader is introduced to many useful subroutines and programming
tools, such as screen utilities, print utilities, a machine language
monitor, a hexadecimal dump tool, a move tool, a disassembler, and a
simple, screen-based text editor.
