Lacking a test case, I'm guessing a little... 

#!/usr/bin/perl

# http://perlmonks.org/?node_id=1192179

use strict;
use warnings;

my @seq = map qw( A C G T )[rand 4], 1..1e2; # fake for missing test c
+ase
$_ = join '', @seq;
print "$_\n\n";

print "ORF: $-[0]-", $+[1] - 1, " $&$1\n"
  while /ATG(?=((?:.{3})*?(?:TAG|TAA|TGA)))/g;

I'm also printing a little extra for checking purposes.
