After we’ve placed all of the dots for our character, we need to turn them into numbers that the printer can understand. To do this, go down each column and add up the value of each dot. The numbers placed on the
Let’s take column one as an example. The first dot is in row |
| ||||
two. Row two has a value of 2 on the |
| ||||
is in row three and it has a value of 4. These are the only dots in |
| ||||
this column, so the total value for this column is6 (2 + 4 = 6).Write |
| ||||
this number at the bottom of the column. After adding up the |
| ||||
values for each column, you will have nine numbers to send to the |
| ||||
printer. For the first example, the numbers are: 6,9,0,9,118,9,0, |
| ||||
127,O. |

The code to define a downloadable character to the printer is: | - | ||||
|
|
|
|
| |
CHR$(27) CHR$(42) CHR$(l) c, d, t, t2 t3 t4 t, te t, te tS | - | ||||
The c, is the character we wish to redefine. In the example, |
| ||||
we’ll redefine the | @ symbol | (CHR$(64)). When we activate | - | ||
downloadable characters and this character is sent to the printer, |
| ||||
the downloaded character will be printed. The d, is the descender |
| ||||
data. For now, we’ll just leave that as zero. The t, through t, are |
| ||||
the column totals across the bottom of the graph. |
| ||||
So the complete code sequence would be as follows: | - | ||||
CHRW); | CH NW; | CH R$(l); | CHR$(64); | CH R$(O); CH R$(6); | |
CH W(9); | CH W(O); | CH W(9); | CH R$(118); | CH R$(9); CH R$(O); | - |
CHR$(127); CHR$(O). |
