The Commodore 64 has become one of the most popular home computers in Europe and the USA. It is a versatile and interesting machine. The aim of this book is to show you how to enhance its abilities still further, by learning the rudiments of Machine Code programming. Want to fill the TV screen with a grid of symbols, in the twinkling of an eye? Move sprites around fast enough to playa reasonable game? Count how many times the REM character occurs in a program? Then it's Machine Code you'll need. It places many more demands on the programmer than BASIC does; but as a reward, it expands the range of tasks that your computer can do.
