DUMPING OUT ALL THE NAME/VALUE PAIRS

The dump method produces a string consisting of all the query's name/value pairs formatted nicely as a nested list. This is useful for debugging purposes: 

    print $query->dump

Produces something that looks like: 

    <UL>
    <LI>name1
	<UL>
	<LI>value1
	<LI>value2
	</UL>
    <LI>name2
	<UL>
	<LI>value1
	</UL>
    </UL>

You can pass a value of 'true' to dump in order to get it to print the results out as plain text, suitable for incorporating into a <PRE> section.

As a shortcut, as of version 1.56 you can interpolate the entire CGI object into a string and it will be replaced with the the a nice HTML dump shown above: 

    $query=new CGI;
    print "<H2>Current Values</H2> $query\n";
