If you don't want to use ATARI BASIC (the programming language that is built into your ATARI 130XE), you can temporarily disable the language in several ways: plug in a software cartridge; hold down the IOptionl key when you turn on the computer; type BYE to exit to the Self Test; or, if the computer is connected to a disk drive, type DOS to activate the Disk Operating System. (For more details, see Exploring ATARI BASIC.) 12
