var</CODE>
 returns the contents of that variable. In this case, if variable <CODE>
b</CODE>
 has the value <CODE>
test</CODE>
, then the command above is equivalent to the command:</P>
<PRE>var a test</PRE>
<P>
Brackets can be used in more complex ways. for example, if the variable<CODE>
 b</CODE>
 has the value <CODE>
tmp</CODE>
 and the variable <CODE>
c</CODE>
 has the value <CODE>
val</CODE>
, then the command:</P>
<PRE>var a test[var b].[var c]</PRE>
<P>
is equivalent to the command:</P>
<PRE>var
