Figure 7-l shows what this program will print. If your chart
doesn’t look like this because it has regular letters and numbers
instead of the special symbols, then your computer is only using
seven bits (unless you have set DIP switches 2-2 and 2-5 off by
mistake). You can get the correct printout by changing line 100
to this:
100 LPRINT I;CHR$(27);">";CHR$(I);CHR$(27);"=";CHR$(g);
So how are all of these strange characters used? Here is a
short program that demonstrate how the graphics characters
can be combined to create a figure: the 5 of clubs.
