coll - Edit 6502 Manual

This book was produced in EPUB format by the Internet Archive.

The book pages were scanned and converted to EPUB format automatically. This process relies on optical character recognition, and is somewhat susceptible to errors. The book may not offer the correct reading sequence, and there may be weird characters, non-words, and incorrect guesses at structure. Some page numbers and headers or footers may remain from the scanned page. The process which identifies images might have found stray marks on the page which are not actually images from the book. The hidden page numbering which may be available to your ereader corresponds to the numbered pages in the print edition, but is not an exact match; page numbers will increment at the same rate as the corresponding print edition, but we may have started numbering before the print book's visible page numbers. The Internet Archive is working to improve the scanning process and resulting books, but in the meantime, we hope that this book will be useful to you.

The Internet Archive was founded in 1996 to build an Internet library and to promote universal access to all knowledge. The Archive's purposes include offering permanent access for researchers, historians, scholars, people with disabilities, and the general public to historical collections that exist in digital format. The Internet Archive includes texts, audio, moving images, and software as well as archived web pages, and provides specialized services for information access for the blind and other persons with disabilities.

AUTHOR'S PREFACE

EDITORIAL ELEMENTS OF GOOD PROGRAMMING

When asked to lecture on assembly language programming two of the most often asked questions I get is "What are some good techniques in programming the 6502?" and "Most assembler manuals expect you to know too much before you start, why don't they have tutorials?" In response to the second question, I feel that there are a number of books in the marketplace that explain, in great detail, what is required for good assembly language programming. The problem in the beginner getting the most out of it leads back to "the first question, where my overwhelming response is to be a good programmer the first requirement is to KNOW THE INSTRUCTION SET OF THE PROCESSOR YOU ARE WORKING WITH. And by knowing the instruction set, I mean, knowing exactly what each instruction does for you. I can pick up almost any magazine and see articles with assembly listings that demonstrate my point (and these people must have some proficiency or else they wouldn't be published). A typical example might be:
