This book, written for the user of the BBC Micro, concentrates on the programming and application of the machine, assuming little or no knowledge on the reader's part. Early chapters introduce some practical points on programming the micro including functions, subroutines, procedures, program development and program libraries, etc.

Following chapters cover features of BBC BASIC as applied to graphics, words, numbers and the machine's sound facility. The book covers slightly more advanced topics such as machine code, Hex, assembly language programming, interfacing and file handling. The final chapter looks at hardware, and appendices list the hardware specification, error codes, ASCII codes and the 6502 instruction set.
