You're not using the arguments to multiComp(), either use @_ instead of @out, or skip the intermediate array (which is probably pretty inefficient, and do something like this: 

my $out;
while (<>) {
  chomp;
  $out .= $_;
}

Note that chomp() removes the current record separator so it won't by default work with DOS textfiles under unix for example.
