Have fun creating your own designs with these characters. You may
wish to SAVE the program before proceeding.

Line Graphics

The RX series printers have a set of line-graphics characters stored
in ROM. In the following program, we define a similar set.
What are line-graphics characters? They are a set of characters 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 entering it.
We will add to the program that you built and saved as STRATA in
the last chapter. LOAD in the STRATA program and delete lines
and 190. Then add these lines:
130 LPRINT CHR$(27)"&"CHR$(0)"a1";
140 FOR Y=l TO 12: LPRINT CHR$(139);
170 LPRINT "a b c d e f g h i j k 1"
Remember, if your computer cannot send lowercase letters, use the
ASCII values for the letters you need (See Appendix A). Add:
