CGI.pm has a method, param(), which when called with no arguments, returns a list of CGI parameters. When called with one of the parameters as an argument, param() returns its value. The following scriptlet gets its parameters and prints their values, in quotes.

use CGI;

my $q = new CGI;

# so the output won't be interpreted as HTML
print $q->header('text/plain');
print "$_ = '", $q->param($_), "'\n" for $q->params;

Update: Oops! left out the second call to param()!
