Hi Monks!
A few questions here, first on the code I posted is about which line is more efficient and why the commented one is giving me a uninitialized error: 
$data = do { local $/; <DATA> };
#do{$data = $data . $_ } while (<DATA>); #gives a uninitialized value 
+in concatenation

I would like to use "__DATA__" twice is that possible? Also I need to pass the values of variables ($date - $location) into the html inside the "__DATA__", any suggestion? If I run this I am getting the second "__DATA__" printed with the rest of the html code. My goal here is to separate as much as I can the HTML from the Perl.
Here is the code sample I am using: 
#!/usr/bin/perl

use strict; 
use warnings;
use Date::Calc qw( Today Today_and_Now Date_to_Days Add_Delta_Days Del
+ta_Days Decode_Date_US );

my $display=qq();
my $data = qq();

my $date = sprintf "%02d/%02d/%04d", (Date::Calc::Today())[1,2,0];
my $location = "BR";

$display .= qq(\n\nStart Display\n\n);
$data = do { local $/; <DATA> };
#do{$data = $data . $_ } while (<DATA>); #gives a uninitialized value 
+in concatenation 

$display .= $data;

$display .=" <tr>
             <td>more data</td>
            </tr>
            <tr>
             <td>end of rows</td>
            </tr>
           </table>\n";

print $display;


__DATA__
<table width="100%" border="0" bgcolor="#ffffff" cellpadding="0" cells
+pacing="0">
                <tr>
                  <td colspan="2">&nbsp;</td>
                </tr>
                <tr>
                  <td width="60%">All Names List from:</td>
                  <td width="40%" align="left"><b>$date</b></td>
                </tr>
                <tr>
                  <td width="100%" colspan="2">&nbsp;</td>
                </tr>
              </table>

__DATA__
<table width="100%" border="0" bgcolor="#ffffff" cellpadding="0" cells
+pacing="2">
                <tr>
                  <td><b>Name</b></td>
                  <td><b>Address</b></td>
                  <td><b>Phone</b></td>
                  <td><b>Email</b></td>
                  <td><b>$location</b></td>
                </tr>
                <tr>
                  <td colspan="5">&nbsp;</td>
                </tr>
