DESCRIPTION OF THE RD,(JL II COMMAND
• Function:
The IW command specifies a plotting area. This area is called a "window".
• Format:
IW Xl lower left, Yl lower left, X2 upper right, Y2 upper right [Terminator]
IW [Terminator]
• EJ<ample:
LPRINT "IWIlI.IlI.1Ille.lelll;"
LPRINT "IW;"
• Parameter range and default value:
The default value and range of parameters are the same as the maximum plotting
area shown in Table IW-l. They vary with setting the DIP Switch 1- (]). Setting
parameters out of this range does not cause any errors. Areas out of the maximum
plotting area are set to the limit of the maximum plotting area.

• EJ<planation:
A window follows the values of four parameters. It is set to the default value if no
parameters are keyed in.
If the four parameters have not been scaled, they are discriminated as plotter coordinate
values. If scaled, they are discriminated as user coordinate values. Then, they become
the X-Ycoordinates at the lower left corner and upper right corner of the window. If
the value of "Xl lower left" is greater than that of "X2 upper right" or if the value
of "Y 1 lower left" is greater than that of "Y2 llPper right", they are replaced with
each other so that always Xl
<
X2 and Yl
<
Y2.
Any window is set to the default value when the power is turned ON or when the
IN or DF command is executed.
You can use the IW command to set a plotting area in the following situations: When
a plotting paper is smaller than the plotting area or in case there are many drawings
in the area of one plotting paper and you want the DPX-3300 to draw part of the
entire drawing.
