<p>
The <CODE>VARNAME</CODE> function accepts a variable, either string
or numeric, as its argument, and converts that variable name into a string. This function can
be useful in scripts where a variable is passed to the script as one of the generalized
<CODE>?</CODE> parameters. The variable name could then be converted
to a string for display or manipulation.</p>
<p>
<font size="+1" color="green">Example</font></P>
<p>
The following script shows one way in which the <CODE>VARNAME</CODE>
function could be used.</p>
<p>
<font color="blue"><pre>
t1 = varname(?1) ! 1st variable name passed to the script converted to a string
t2 = varname(?2) ! 2nd variable name passed to the script converted to a string
graph ?1 ?2 ! plot graph of 2nd variable versus 1st variable
text 'graph of '//t1//' vs '//t2 ! label the plot with the command
</pre></font></p>
