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.
