Drawing Circles
The CIR (draw circle) command draws a circle of a specified radius using the line thick-
ness set by the SPD (set pen diameter) command. The circle drawn is centered on the
current cursor position; the position of the cursor remains unaffected. See the following
example:
!R! RES;
UNIT C;
SPD 0.1;
MZP 8, 8;
CIR 1;
CIR 2;
CIR 3;

Figure 2. 7. Circles
Lines 1, 2 and 3 start PRESCRIBE mode, reset the printing system to its default parame-
ters, establish the unit of measurement as centimeters, and set the line width to 0.1 centi-
meters.
Next, the MZP command moves the cursor to the point that is 8 centimeters to the right
of the left edge limit and 8 centimeters below the top edge limit.
Lines 5, 6, and 7 draw three circles with radii of 1, 2, and 3 centimeters.
Drawing Filled Shapes
The standard graphics mode provides two types of filled shapes: arcs and blocks. Such
shapes are filled with one of the printing system’s predefined patterns, or with a user
defined pattern.
Filled areas of other shapes can be printed using path mode graphics. For details, see the
explanation in section Path Mode Graphics on page 16.
