Well if you have a form like so...

<form action="recordQuote.pl">
<input type="text" name="quote" value="" />
<input type="submit" value="Submit" />
</form>
[download]

And then in recordQuote.pl...

#!/usr/bin/perl -wT

use strict;
use CGI;

my $q = new CGI;

my $quote = $q->param("quote");

open FILE, ">>rqhold.dat" or die "Can't open rqhold.dat: $!\n";
print FILE $quote, "\n";
close FILE;
[download]

That will take the user's input and append it to the file.
