This is a good book with a really superb two level index - a normal one and an index to all the procedures used in the book.

There is quite an emphasis on mathematics in this book, more so than in McGregor's Advanced book. This is necessary as the book concentrates on graphics whereas McGregor's book covers features other than graphics. This book covers graphics in great detail, and will provide you with lots to think about and try. However the price is pretty hefty at £10. Some of the programs in the book are very long so it makes sense to supply these on cassette.
