<P>
 <em>Note:</em> The value of the <CODE>SCRIPTEXTENSION</CODE>
 characteristic is a string and not a numeric value. So, if you enter:
 <CODE><font color="blue"><a href="../Commands/Get.htm">GET SCRIPTEXTENSION X</a>
 </font></CODE> the variable <CODE>X</CODE> will be a string variable.</P>
<p>
 The <CODE><font color="blue"><a href="../Commands/Set.htm">SET SCRIPTEXTENSION</a>
 </font></CODE> command is used to
 redefine the default file extension for script files.  The original default file
 extension is <CODE>pcm</CODE>. This file extension applies to the
 <CODE><a href="../Commands/Execute.htm">EXECUTE</a></CODE> command only.
 If you enter the file name without a file extension, the default extension is automatically
 appended to the file name.</P>
<P>
 The case of the extension is kept as entered.</P>
<p>
 <font size="+1" color="green"><B>Examples</B></font></P>
<p>
 If you have a script file named <CODE>script_file.pcm</CODE>, you can execute
 this file with the command <font color="blue">@<CODE>script_file</CODE></font> or with
 the command <font color="blue">@<code>script_file.pcm</code></font>.</p>
<p>
 If you have a script file named <CODE>script_file.extrema</CODE> you can
 execute this file with the command<br>
 <font color="blue">@<CODE>script_file.extrema</CODE></font><br />
 or<br />
 <CODE><font color="blue">SET SCRIPTEXTENSION extrema</font></CODE><br>
 <font color="blue">@<CODE>script_file</CODE></font></p>

<p>You can also use character variables, for example:</p>

<font color="blue"><pre>
T=`script_file'
SET SCRIPTEXTENSION extrema
@T
</pre></font>
