Column reservation numbers

The graphics command requires more than one number to specify how many columns to reserve because one line can use thousands of columns, but the printer does not use numbers larger than 255 decimal. Therefore, the graphics mode command uses two numbers for reserving columns.

To figure nl and n2, divide the total number of columns by 256. The result is n2; the remainder is nl. Since the command is set up for two numbers, you must supply two even if you need only one. When you need fewer than 256 columns, just make nl the number of columns you are reserving and make n2 a zero.
