If you are frustrated by the limitations of BASIC and want to write faster, more powerful, space-saving programs or subroutines, then
Spectrum Machine Language For The Absolute Beginner is the book for you.
Even with no previous experience of computer languages, you will be able to discover the ease and power of the Spectrum's own language. Each chapter includes specific examples of machine language applications which can be demonstrated and used on your Spectrum, as well as a self-test questionnaire.
At the end of the book, all this brought together into an entire machine language program - from design right through to the complete listing of an exciting, original arcade game.
