Notes
------------
XBASIC extends Atari BASIC by adding 30 functions, including string arrays, simplified Player/Missile graphics and sound and memory functions. XBasic takes up about 2K of RAM and is called into action from basic through the USR function. Each function is a separate, "pre-programmed" machine language subroutine which the user simply inserts into his own basic code. SUPERware allows XBASIC to be freely included in user-developed software for sale, as long as the XBASIC program source code is inserted along with a credit screen.
