This is a rare treat: a book that tries to be a Jack of all trades, and succeeds. In one thin volume there are games, utilities, a word processor and a turtle graphics package. The programs are easy to type since they are explained thoroughly, line by line.

Although the listings have been typeset they appear to be bug-free.

But there are flaws. The games and graphics sections require the use of two joysticks, though this is not stated explicitly, which could add considerable cost to the unprepared. Also, the omission of an index is shameful.

Of the two games, I found one interesting (Sub-hunt); the other, Blocks, is like a two-dimensional Rubik's Cube. But both are useful since they have been programmed with skill and annotated fully.

The graphics section comprises three programs. The drawing package and a 3D wireframe drawing routine are not special, but the third, Logo, is an impressive turtle graphics package.

In the third section, a word processing program makes the Dragon behave like a respectable word-processor. This is followed by a rather predictable phone bill reckoner and directory, neither of which add much to the book.

At the end come a handful of useful utilities, including a Tandy-to-Dragon converter (and vice versa), a tape catalogue routine and a machine code monitor.
