2.7.6 Graphic mode statements .
The graphic mode statements become effective after the MODE GR statement has been executed. When
this statement is executed, the current pen location is set to the origin (X= 0, Y = 0). However, the origin
can be set to any location. Be careful not to specify a location which is out of the print area, as this may
damage the pen or cause other problems.

This statement draws a line from the current pen location to location (x
1 ,
y
1 ) ,
then
draws a line from (x
1 ,
y
1 )
to (x

,
y

and so on. n specifies the type of line drawn
as shown below.
n
=
1 : solid line
n
=
2 to 16: dotted line
If % is omitted, the previous value of n is assumed. The initial value of n is 1 (solid
line).
