`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;` [download] Update: Oops! left out the second call to `param()`! dmm You can give a man a fish and feed him for a day ...

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;
