The second edition has been thoroughly revised to take account of the recent changes in the computer world and in examination syllabuses, while retaining the same step-by-step approach. New material includes: subprograms, graphics, file handling, checking and documenting programs, and program structure. All aspects of computer programming in BASIC needed for GCSE Computer Studies examinations are covered in a straightforward manner. Enthusiasts with their own microcomputers will appreciate the structured approach to programming, and the wide variety of examples included.
