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.

n Integer from 1 to 16
xi Number indicating the X coordinate (xi = —480 to 480; the limit varies
depending on the current, pen location.)
yi Number indicating the Y coordinate (yi = —999 to 999)
This statement draws a line from the current pen location to location ( x

), 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).
