TRS·80
I
The TRS-80 Microsoft BASIC is quite similar to the Microsoft
BASIC used in the demonstration programs. The only exception
is the width commands, which are explained in the documenta-
tion accompanying the TRS-80 Microsoft BASIC programs. You
may also refer to the amended program listing at the back of this
Appendix.
