Beyond BASIC

Beyond Basic has been written to provide an easy introduction to assembly language on the British Broadcasting Corporation Microcomputer. The book incorporates a number of special features to help you get started with assembly language programming:

• The book is built around practical programming problems - often taking tasks you can do in BASIC and asking 'How can we do that in assembly language?'

• The 6502 instructions are introduced as they are needed to solve problems

• Each step is illustrated by fully worked examples

• As you work through the book, you are given plenty of opportunity to check your progress with self-assessment questions. Complete answers are given to all these questions.

• A cassette tape of all the main programs is also available.

The book will teach you how to use most of the 6502 instruction set and how to write programs to: perform arithmetic calculations, use loops and decisions, create lists and tables and perform complex operations on BASIC variables (e.g. sorting a BASIC array). The book also deals in detail with how to access the British Broadcasting Corporation Microcomputer operating system and includes assembly language routines for graphics and sound.
