Although it is relatively easy to learn to program the Commodore 64 in BASIC, advanced programmers need to know much more than how to use the fundamental commands. It is essential to know how BASIC works and utilises memory. The ability to add further commands is often invaluable in speeding up and simplifying a program.

This book explains all these details and sets out a unique library of routines to add extra commands to BASIC.

With this book you will not only learn far more about the Commodore 64 and its dialect of BASIC. You will also learn how to expand the scope and function of your programs; the utilities included in this book will make the writing of such programs much easier.
