COMPUTEI's Second Book of Commodore 128 offers dozens of programming tips, tutorials, applications, and games that will entertain you and inform you. No matter what your interest or computing background, the programs included here have been chosen to make your 128 more useful than ever. If you like games, try "Puzzle Grid"; it's trickier than you might think (and it also gives you an opportunity to create your own puzzles). "Hex War" is a game of thought and strat egy rather than quick reflexes. "Miami Ice" requires a com bination of fast action and concentration. And "Pig$ for Buck$" will delight kids of all ages. If programming is your interest, you'll find hints and tips to make using your disk drive easier and take less time—time that can be spent on programming. "Commodore 128 Hi-Res Text Manipulation" explores some techniques for adding text to your hi-res artwork. In "ESCaping with the 128," you'll be shown how to access 27 new screen-editing features with ESC-key sequences, and you'll learn how to use them in your own programs. And there's an article on machine language that examines some basic architectural features of the 128. Graphics and music programs are fun to work with and have practical applications for your programs as well. "Artimation" is a way to use BASIC 7.0's hi-res graphics state- pi ments to create kinetic computer art. "Mastering 128 Sound and Music" explores the sound statements that can help you generate high-quality musical arrangements. p"\ The CP/M operating system offers a lot to programmers. ■ * An introduction to CP/M mode tells you how to boot CP/M, discusses CP/M commands, and shows you how to create a rn PROFILE program. In addition, an article on public domain CP/M software clues you into gaining access to a whole new world of free and inexpensive software. r*) COMPUTEI's Second Book of Commodore 128 is also strong - * in applications and utilities. You'll find a database program, a u u LJ program that continuously displays a scrolling message on the screen, and a way to create a complete custom character set for the 128's 80-column screen. And you'll learn how to personalize your 128—changing the defaults so that the com puter automatically turns on with your personal preferences of colors, tab settings, repeating keys, and cursor modes. There I | are utilities that enable you to redefine keys to print whatever characters you choose, that speed up the 128's action in 64 mode, and that automatically load and run any 64 program from disk when you boot your system. Written clearly and concisely, COMPUTERS Second Book of Commodore 128 will make your computer more valuable than ever. All the programs have been fully tested, and "The Auto matic Proofreader" and "MLX" will assist you in typing in programs correctly the first time. the prbgfcams in COMPUT&'s Second BookofCommodore 228 ase re^dy tQ type in and run.
