Beyond Basic is written for anyone who has a good grasp of Basic and who
wants to learn how to program in assembly language.
The chapters include addition and subtraction, jumps, addressing modes,
multiplication and division, and operating system calls.
The reader is taken from his first assembly language program - simply
loading the accumulator with a number - to sorting a Basic string array.
Each step along the way is explained very simply and clearly.
There are many exercises at each stage to test the reader's understanding
of the important principles involved.
There are several books around now which aim to teach assembly language
programming, but in my opinion this is by far the best text for beginners.
There is a cassette available which has all the programs in the book on it.
If you're the lazy type, you can load each program from tape instead of
tapping it in at the keyboard.
This is an excellent manual which I strongly recommend.
