Preface This publication contains a complete description of the BASIC programming lan- guage as it is defined by IBM. BASIC is a terminal-oriented language which was developed for people who wish to solve problems of a mathematical nature, but who need not acquire expertise in the extensive discipline of modern computer programming. The syntax and semantics of the BASIC language are presented here for the reader who is already acquainted with the fundamental techniques and terminology of programming. The first section of the book describes BASIC program structure and data representation. In the second section, the BASIC statements are grouped ac- cording to general function (data definition, input/output, etc.) and presented with examples of their use. Sample BASIC programs and a formalized definition of the language are included in appendixes.
