Since more and more users of the ATARI personal computers write programs in machine language, more and more "workhorse"- routines, performing standard tasks, are required.
This book contains a variety of programs for the real computer "Hacker" and the machine language programmer.
All the programs have been fully tested and a complete source code is provided.
I extend my thanks to Franz Ende for the translation and Karl Wagner for his proofreading.
