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.
