Demonstration Programs
Along with our discussion and examples of the LX-80 features, we
include demonstrations in the BASIC programming language so that
you can see these features in action. Although we know that you will
probably not do much of your printing using BASIC, we chose it for
our demonstrations because most computer systems include some
form of BASIC, so our examples are ones that almost every one of
you can try.
You don't need to know anything about BASIC to type in and run
these programs. Just check your BASIC manual to see how to load
BASIC in your computer and how to run a program. As you run the
programs (or even as you read the explanations and look at the
printed examples), you learn how the LX-80 responds to the mes-
sages your computer sends it by printing letters, numbers, symbols,
and graphics in various print modes.
Even if you never use BASIC again, you will know the capabilities
of your printer, capabilities that can often solve your printing prob-
lems. For example, if you need a special symbol, such as the Greek
character Z:, you will know that you can turn to the chapter on
user-defined characters and create such a character.
