SpeedScript is a 1985 COMPUTE! Publications book by Charles Brannon that documents SpeedScript 3.1, a compact all–machine language word processor for the Commodore 64 and expanded VIC-20. It explains how to type in and run the program, use MLX and the Automatic Proofreader to enter the machine-language listings accurately, and operate the word processor’s editing, search-and-replace, saving, loading, disk, and printing features. The book also includes the SpeedScript source code, program listings, ScriptSave for automatic disk saves, keyboard overlays, quick-reference cards, and an index, making it both a user manual and technical reference for one of COMPUTE!’s most popular published programs.
