COMPUTE!’s Second Book of Commodore 64 is a 1984 anthology of programs, tutorials, utilities, games, and reference material drawn from COMPUTE! and COMPUTE!’s Gazette for Commodore 64 users of many skill levels. It includes practical applications such as SpeedScript, a machine-language word processor, plus a mailing list manager and spreadsheet; games such as Spike and Martian Prisoner; educational programs including Wordspell, Munchmath, and The Note Name Game; sound articles and tools for working with the SID chip; graphics tutorials on custom characters, sprites, and motion; programming lessons on function keys, arrays, and adding new BASIC keywords; and utilities such as SuperBASIC 64, Copyfile, program merging, and a program recovery tool. The appendices add typing guidance, screen/code tables, keycodes, MLX, and the Automatic Proofreader, making the book both a software collection and a practical Commodore 64 programming reference.
