Hi monk,
I am working with a Perl which looks like below :

sub display { $self = shift; if(exists $error){ $html .= "<table border=0>"; $html .= "<tr>"; $html .= "<td align=center ><b>".$self-> {error} +."</b></td>"; $html .= "</tr>"; $html .= "</table><br>"; } $html .= <<END; <table border=0> <tr> <th bgcolor="#CCCCEE">Name</th><th>&nbsp; </th> +<th bgcolor="#CCCCEE">Address</th> </tr> <tr align=center> <td bgcolor="#EEEEEE">@{[ $qry->popup_menu(-id=>'ID +', -name=>'PS', -size=>10, -values=>$array_ref, -labels=>$hash_ref, +-onChange=>"fetchData(id,'','','')") ]}</td> </tr> </table> END return $html; }

In the above code, what does this <<END and END mean ?
how can I change the code which is in between that <<END and END, to insert a if-else condition for that popup_menu.

To clarify further, depending on some values passed to that function, I want another popup_menu which will have a onload function instead of onChange.
In this above code, how can I do that by writing a if-else condition.
