Passing Functions - Cont'd

• A more common example is the use of functions to handle input arguments:

  use Getopt::Long;
  my $data    = "file.dat";
  my $length  = 24;
  my $verbose = 0;
  my $help = 0;
  my $result = GetOptions (
     "length=i" => \$length,
     "file=s"   => \$data,
     "verbose"  => \$verbose,
     "quiet"    => sub { $verbose = 0 },
     "help|man" => \&help,
  );
  sub help {die "Usage stagement...\n"}
