Photocopy the grid in Figure 9-1 to help design your new characters. We will
use a tiny representation of a telephone symbol for our example.
Figure 9-1.
Use this grid (or one similar to it) to define your own characters.
Assigning the character data
Now, we calculate the vertical numerical values of the columns of dots, and
enter them underneath the grid. Each vertical column (which has a maximum
of 24 dots) is first divided into three groups (or two groups for super/
subscripts) of eight dots. Each group of eight dots is represented by one byte,
which consists of eight bits.
This is where the numbers down the left side of the grid come in. Notice that
there is a number for each row of dots and that each number is twice the
number below it. By making these numbers powers of two we can take any
combination of dots in a vertical column and assign them a unique value.
