it’s possible to have a graphics image as wide as 480 dots on SG-10 or 816 dots on SG-15. So to figure out how many columns of graphics data to expect, SG- lo/15 multiplies n2 by 256 and adds the value of nl. If you divide the number of columns by 256, then n2 is the quotient and nl is the remainder (why not let your computer figure it out for you: if the number of columns is as-

signed to variable X, then nl =X MOD 256 and n2 = INT(X/256)). Table 10-l might make things even easier.

nSpecifying the graphics data

Now that we’ve told SG-lo/15 how much data to expect, we better figure out how to send that information! Just as you do with download characters, with dot graphics you have control

.over the firing of every single pin on SG-10/15’s print head. In Figure lo- 1, you can see that we’ve labeled each pin on the print head with a number, as we did with download characters (you should note one important difference: this time the top pin has the highest value; for download character definitions it is the bottom pin). And specifying pins to Iire is done in the same way: to tire the second pin from the top, for instance, send a CHR$(64).

Firing several pins at once is done in a similar fashion, For ex- ample, to print the first, third, and fourth dots, add their values (128 + 32 + 16) to send this total: CHR$(176). This is one byte of graphics data; it would replace ml in our format statement on page 104.
