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 a Greek let-
ter, you will 
know that 
you can turn to the chapter on user-defined
characters and create such a character.
If you don’t want to do 
the 
exercises in BASIC, you don’t have to.
In most cases the software 
that 
you use for word processing, business,
or graphics does 
the 
calculating and communicating with the printer
for you. All you need to do is install your software as explained in
Chapter 4.
Running BASIC programs. . .
This section describes how to run the BASIC demonstration pro-
grams in this manual; it is not a tutorial in BASIC programming.
Although there are many versions of BASIC, the programs in this
manual are designed to work with the two most popular ones: Micro-
soft™ BASIC and IBM PC BASIC. If you have another version, you
can run these demonstration programs by making a few changes.
Appendix D has instructions for using Applesoft™ BASIC; for other
versions of BASIC, consult the appropriate manual.
When you type these programs, be sure to include all spaces and
punctuation marks, especially semicolons. Press 
RETURN 
at the end
of each line. (On your computer the 
RETURN 
key may be marked    
or 
ENTER.) 
Computers that use a 40-column display may break
some lines into two parts on the screen, but that does not affect the
operation of the program. If you make a typing mistake, retype 
the
whole line, including the line number; the new line will replace the old
one.
When you 
have 
typed all 
the lines, 
type 
RUN and press 
RETURN
to run the program.
If you have made changes to a program and want to see all of it on
the screen, type 
LIST and then press 
RETURN 
to see the program on
your screen. When you are completely through with one program
and want to start another, 
type 
NEW and press 
RETURN.
