I'm using the function  index to find the position of a couple of stopping strings. Say I have 3 different stopping strings. ie.  $end1, $end2, $end3 In a file I need to find the first occurence of either one. Could I do something like this. 
$startcod = index($seq, $start);
print "$startcod\n";

$endcod = index($seq, $end1 || $end2 || $end3, $startcod);
print "$endcod\n";

Or is there another way to do it. Thanks!
