The minimum width of a character is five dots.

The user-defined characters may use eight dots vertically.

Dots cannot overlap - that is, you may not have a dot inside a box next to one that is on a line.

You may define any position in the ASCII table.

Photocopy the grid in Figure 5-2 to help design yournew characters. We will use a tiny representation of a car-shaped symbol for our example.

Defining the attribute data

Before you start the definition, you will need to decide exactly where in the regularASCI1 set you want to place your characters. After downloading, you access your new character by sending the code for the character you replaced.

Next you must choose whether to make the car symbol an ascender or a descender. This determines how the character is seated on the line:

As c e n d e r : f:‘-::;;1:::

Descender

: i:‘:;:;.>Fi:5:

We decided that our car symbol will not be a “descender”, so a figure “1” is written next to Descender on the grid. If your character is a descender, write a “0” next to Descender.
