Graphics Even in single-density graphics mode, one 8-inch line can accommodate 480 columns of graphics; jr( quadruple-density, almost 2OOO columns can fit on the same g-inch Bne. Since the &inter does not use decimal numbers larger than 255, 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 ir2; 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 ti& 256 cohmms, just make nl the number of cohunns you are resa+@ and make &a zero. For example, if you wish to &cl 1632 c6lumns of .gr&phica data; nl should be 96 andn2shouldbebl+rusel632 - % + (6 x 256). If you are using a programming language with MOD (modulus) and INT (integer) functions, you can use the following formulas to calculitte rr2

Graphics

Even in

single-density

graphics mode,

one

8-inch line can accommodate

480

columns of graphics;

jr(

quadruple-density,

almost

2OOO

columns

can fit on the same g-inch

Bne.

Since the &inter does not use

decimal numbers larger than

255,

the graphics mode command uses

two numbers for reserving columns.

To figure

and

n2,

divide the total number of columns by

256.

The result is

ir2;

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

ti&

256

cohmms,

just make

the number

cohunns

you are

resa+@

and make

zero. For example, if

you wish to

&cl

should be

If you are using a programming language

with

MOD (modulus) and

INT

(integer) functions, you can use the following formulas to
