Hello dear PerlMonks, I'm trying to match a certain pattern in a DNA sequence and retrieve the position of the match. This wouldn't create a problem, but I don't know how to use the pos() function on an array. I also don't know how to use $- with an unknown amount of matches. This is what I have so far: 

@TATA = ($seq =~ m/TATA[A|T][A|T][A|T|G]/i)
 $number_of_TATA = @TATA;
 if ($number_of_TATA > 0){
    print "The positions of the TATA box are:";

  foreach (@TATA){

    $TATA_position=pos($TATA)-7;
    print $TATA_position."\n";
 }

I'd greatly appreciate the help! thanks a lot!
