Pratical Spectrum Machine Code / Steve Webb

Pratical Spectrum Machine Code. Af Steve Webb. Udgivet i 1984. Bogen er på engelsk. 116 Sider. If you have grown tired of the slowness of your BASIC programs, and wish to write faster and better programs-in particular games - then this book is for you. The book assumes that you have no knowledge at all of Machine Code. It begins by explaining the Machine Code equivalents of the main BASIC instructions, such as LET, IF, FOR/NEXT, PRINT, GOTO, GOSUB, ADDITION and SUBTRACTION. It goes on to describe in great detail the individual routines of a simple Space Invader game, and how these routines are linked together. Finally you will be shown a few simple routines which can be used with BASIC programs. Also included are a few games to demonstrate the effectiveness of Machine Code programming. * Learn how easy it is to incorporate Machine Code routines within your BASIC programs. * Use Machine Code to create far better sound effects than can be achieved with the BASIC beep command. Whether you simply wish to write a routine to enhance your BASIC programs, or write a fully-fledged Machine Code program, you will find this book extremely useful. It removes the theory surrounding Machine Code, presenting it in a way which is both practical and enjoyable to learn. There are a number of questions throughout the book which will test your knowledge of Machine Code programming.
