<P>
Choosing a window with the <CODE>WINDOW</CODE> command, which has its lower left corner at
<CODE>(lowx,lowy)</CODE> and its upper right corner at <CODE>(upx,upy)</CODE>,
is equivalent to choosing the graphics sub-window with the
<a href="../SetCommand/setcommand.htm"><CODE>SET</CODE></a>
command. That is, the following command:</P>
<P>
<code>WINDOW n lowx lowy upx upy</code></P>
<P>
is equivalent to the following:</P>
<p>
<PRE>
SET %XLOWERWINDOW lowx
SET %YLOWERWINDOW lowy
SET %XUPPERWINDOW upx
SET %YUPPERWINDOW upy
</PRE></p>
<P>
Using the <CODE>SET</CODE> command to define a window is <EM>not</EM> recommended. When the
<a href="../ClearCommand/clearcommand.htm"><CODE>CLEAR</CODE></a>
command is entered, the window chosen with the last
<CODE>WINDOW</CODE> command is set up, and the values of
<A HREF="../Characteristics/GeneralGraph/xlowerwindow.htm"><CODE>XLOWERWINDOW</CODE></a>,
<A HREF="../Characteristics/GeneralGraph/xupperwindow.htm"><CODE>XUPPERWINDOW</CODE></a>,
<A HREF="../Characteristics/GeneralGraph/ylowerwindow.htm"><CODE>YLOWERWINDOW</CODE></a>, and
<A HREF="../Characteristics/GeneralGraph/yupperwindow.htm"><CODE>YUPPERWINDOW</CODE></a>
are changed. Thus, if their values had been re-defined with the
<CODE>SET> command, these values would be lost when the <CODE>CLEAR</CODE> command is entered.</P>
