I see. I don't seem to have that problem when the param value is from a input field of type 'text' or type 'password'. To make my question more concrete, here's an example 
# html
<tr><td>Username<td><td><input type="text" name="username" size="25"><
+/td></tr>

# cgi
my $username = seewhatsthere(
  data     => param('username'),
  field    => 'Username',
);

sub seewhatsthere {
  my %hash = @_;
  html_start();
  print Dumper(%hash);
  exit(0);
}

# Dumped
$VAR1 = 'data'; $VAR2 = ''; $VAR3 = 'field'; $VAR4 = 'Username';

In the above case, even though the username is not filled, the dumped output is as expected. Which means that if the input type is 'text', passing param() to a list is permissible ( as shown in the code ). Am I getting it right?
