IW - Input window
IW [ X
X1-Window lower left X coordinate
X2-Window upper right X 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 any previous 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 [;]
