three attribute bytes, the first byte describes the character’s left space, the second byte describes the character width. And the third byte describes the right space. Appropriate allocation of data in these three bytes lets you place the character where you like within the grid.

Use the grid in Figure 5-4 to help plot the data. The vertical definition of the character is 18 dots. Each byte therefore represents a third of the vertical definition. That’s 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 of two we can take any combination of dots in a vertical column and assign them a unique value.

If we plot our car-shaped symbol for NLQ, the grid data will look like Figure 5-5.

The defining process is the same as for draft characters, except that you must select NLQ mode, and you must define 69 data. If you wish to print your NLQ characters with the regular character set, the remarks regarding the si- multaneous use of regular and download characters in the draft character section apply equally to NLQ characters.
