You should really take another (closer) look at perlre (or perhaps perlretut). Particularly the bits about using the match operator (m//).

my $count = 0;
foreach (@input) {
 if (/DosID(.{6})/ and $count++ % 2) {
    $dosid = $1;
 }
}

Of course, this overwrites the value of $dosid each time it finds a match, so you might need to change the logic a bit.
