Line Graphics - Epson FX-80 User Manual

Have fun creating your own designs with these characters. You may
wish to SAVE the program before proceeding.
Line Graphics
The later MX series printers have a set of "line graphics" characters
stored in ROM. In the following program, we define a similar set of
characters.
What are line graphics characters, you ask? They are a set of char-
acters that fit together to make borders and outlines for all kinds of
forms. Since they are so useful, we use them again in the next chapter;
be sure to save the next program when you are through.
Once again we will add to the program which you built and saved
(as STRATA) in the last chapter. LOAD in the STRATA program
now, and type:
DELETE 180-190
130 LPRINT CHR$(27)"&" CHR$(0)"al";
140 FOR Y=l TO 12: LPRINT CHR$(139);
170 LPRINT "a bed e
f
g
h
i
j
k I"
Remember, if your computer cannot send lower-case letters, use the
ASCII values for the letters you need (see Appendix A). Add:
