Preface
The ATARI computer is one of the world's most
popular computer systems. Its lightweight, desktop
design and powerful version of the BASIC programming
language place it at the forefront of the new wave of per
sonal computers for office, school and home use.
Any thing but a toy, its hardware configuration and
system software make it a highly useful tool in the
business environment and classroom as well as for prac
tical jobs around the home.
In fact, the system software built into your ATARI
computer is so flexible and versatile that the need for this
book became apparent. There are so many computing
tasks which can be accomplished with the ATARI system
that an introduction to the many techniques is needed.
Applications software are the programs which make
a computer do what you want. This book is written for
those newcomers and beginners, as well as advanced
novices and student programmers, who would like to tap
the vast resources available in the ATARI computer
package. This book, it is hoped, will guide by example, in
struct, and provide insights into the many ways the
BASIC language built into the ATARI computer can be put
to use.
This book is a companion volume to 31 New A TARI
Computer Programs for Home, School & Office.
