Information about how to use the BASIC Interpreter for the IBM Personal Computer. This manual contains the syntax and semantics of every command, statement, and function in the three versions of BASIC: cassette, disk, and advanced.

In addition to the reference material are chapters on BASIC programming concepts and the BASIC program editor.
