Some of the programs are quite long and will present a challenge to those hardy enough to tackle typing them in. You will make fewer errors and become less fatigued, if you attempt only one page at a time. Also, take short breaks between bouts at the keyboard and double check each line for accuracy.

Finally, it is our intention that this book provide the reader with more than a listing of program lines. We hope that it will be a teaching aid that will enable you to write better programs of your own. A wide range of programming styles and techniques are present, and some are better than others—try and find out as much as possible about program structure from these examples. We have loaded and run every program but have made no attempt to alter style—we leave that to you. Change lines, clean up subroutines, reduce lengths where possible, get rid of GOTO statements if you can—experiment!
