Programming the Vic

The VIC-20 is one of the world's most popular microcomputers, and like all best-
selling computers, it is both inexpensive and generally easy to use. But many VIC-20
owners have found that the word "simplicity" does not always apply when writing
their own programs. Official manuals and even the VIC chip's descriptive sheets
have errors. Reliable information has been difficult to find-until now.
This book is designed to teach competent programming on the VIC-20 and to
provide a comprehensive reference text for VIC-20 users. It incorporates both BASIC
and machine language, for although most people learn BASIC first, it is often nec-
essary to use machine language as well to explain or illustrate particular concepts.
When dealing with computers, it isn't always easy to arrange material so every-
thing falls into an apparently natural sequence. But the organization used here
should benefit everyone. This book explains BASIC and machine language by build-
ing on easy-to-grasp concepts, and it includes a chapter on combining BASIC with
machine language to produce extremely efficient programs. It also contains much
useful information on the VIC's internal organization and structure, and concludes
with in-depth examinations of topics such as sound, graphics, disk operation, and
printers.
