push the cartridge firmly into the Cartridge slot on the back of the
computer, and turn on the computer. If you have already been using
another software program, turn off the computer, remove the first car-
tridge, insert the new cartridge, wait several seconds, and turn on the
computer again. (For more information about software cartridges, see
Using Software.)
If you don't want to use ATARI BASIC (the programming language that
is built into your ATARI 65XE), you can temporarily disable the
language in several ways: plug in a software cartridge; hold down the
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.)
