Yes, I have already found a way to get mode for the set of numbers in a couple of ways.

my ($mode_num)=alt_mode_num(@data);
print "Mode : $mode_num\n";

 sub alt_mode_num{
        my %count=();
  
    for (sort{$a <=> $b} @_){
        $count{$_}++;
        }
   my @key= sort{$count{$b}<=>$count{$a}} keys %count;
   #print " Key with highest value is $keys[0] \n";
   return $key[0];       
       
       }

BUT I saw this way of passing the values by ref in this forum and wanted to duplicated it but failed

this is the model I used to try to get my mode sub to look like 

my @num =(1..10);
my @words = qw(hello world inside);
function( {NUMBERS=>\@num, WORDS=>\@words} );
exit;
sub function {
  die "no parameter!\n" unless @_;
  my %opt = %{ shift @_ };

  my @i_words = $opt{WORDS};
  print "this r words", Dumper \@i_words;

  my @i_numbers = $opt{NUMBERS};
  print Dumper \@i_numbers;
}

(one of my problemS) is getting a counter and a compare for highest value.

I specifically wanted this so I can see how it is done properly when using this way
