It would help to actually read the file data (untested change)

sub gethash
  {
  my $fh = shift;
  local $/;
  local $_ = <$fh>;
  s/^\s+//gm;
  s/[\t]+/\t/g;
  my %hash;
  while(/^name\s+(\S+)\n(num.*\n)*/gm )
    {
    my $name = $1;
    $hash{$name} = [$& =~ /^num\s*(.*)/gm ];
    }
  return %hash;
  }
