For the purposes of formatting some longer lines in the BASIC programs have been split into several lines in this document. Where a line starts with a space it forms part of the line above. The original BASIC programs have not had any of their lines split.

Please note that the Second Edition of this book was prepared before the launch of the IYONIX and RISC OS 5. As a consequence some of the information relating to graphics is already out of date. In particular, the graphics card supplied in the IYONIX pc does not support the use of 16-colour screen modes.
Several of the programs in this book make use of 16-colour screen modes: these programs will run on an IYONIX pc, but will switch to a 256-colour mode instead, with the result that the colours shown on the screen will not match those described in the book. Other graphical problems may also appear in individual programs. Readers who work their way through the book may like to try converting the programs to work well in 256 colours as an exercise to test their newly-acquired skills.
The worst-affected of the programs is Munchie, which is the subject of Chapter 11 and later chapters. A special 256-colour version of this program, Munchie_28, is therefore supplied for the benefit of IYONIX pc users.
