X1-Window lower left X coordinate Y1-Window lower left Y coordinate
X2-Window upper right X coordinate Y2-Window upper right Y coordinate
• This instruction sets the window inside which plotting can be performed.
• Graphic units are always used.
• Coordinate values for X1, Y1, X2, and Y2 are integer numbers from 0 to 32,767.
• The order of the pairs (X1, Y1) and (X2, Y2) may be reversed with no change in the window created: "IW
X1, Y1, X2, Y2" is identical in effect to "IW X2, Y2, X1, Y1".
• Using this instruction without a parameter field releases limitations on the plot area.

RO - Rotate coordinate system
RO [
q ][;]
q : Angle in degrees through which the coordinate system is rotated.
• This instruction rotates the coordinate system.
• A value of 0 or 90 must be used for q.
• Using this instruction without a parameter field sets the rotation of the coordinate system to 0 degrees.
PG - Page feed
PG [;]
• Executes a page feed
• • After page feeding, the cursor position return to the home position (0, 0).
