In the program that follows, we’ve used this technique to create
some large numbers. Each digit is actually made up of four
characters-two horizontally by two vertically. This means, of
course, that you must define and print four characters for each
finished digit. We assigned the upper left quadrant of each digit
to ASCII codes from 160 to 169, the upper right quadrant to
codes 170 to 179, and so on. Figure 9-14 shows how one digit
is defined, and Figure 9- 15 shows the final output of our program.
