CLAIRIFICATION TO MY FIRST POST

I guess maybe a good answer must be constituted from code.

I am just using a reference to my data structure. Is there an advantage to changing it to a blessed reference? most of my accessors are generic but a few are specialized. I seek your thoughts and or possible change ideas.

As you can see I put the data into a array then reference it to a hash so I can get at it easily then return the whole thing as a reference. The reason for the array is so I can loop through it to write out the converted data in case your wondering. Also I am following a (MVC) model, view, controller programming style. This is part of the data model.

main.pl

my $buffer = Data::File::Open('all.bin'); 
my %Header = Data::Struct::Define::Header::Get($buffer);
my $objREF_wp = Data::Struct::Wp::wpData(substr($buffer, $Header{ws}{s
+tart},  $Header{ws}{offset})); 

$value = Data::Struct::Wp::n_1_1($objREF_wp);

sub wpData{
    my $buffer = shift;
    my $binString = unpack('b*', substr($buffer, 0));

    my @data;
    my %objREF;

    my $count = 0;

    open(F, "Waypoints.txt") or die $!;
    my @funct = <F>;
    close(F);

    foreach my $line (@funct) {
 
            $line=~s/\r|\n//g;
            my @element = split(/,/, $line);

            my $value = substr($binString, $element[1], $element[2]);

        #### NO BYTES SWAPPING FOR THIS STRUCT

            $data[$count] = $value;
            $objREF{$element[0]} = \$data[$count];
            $objREF{array} = \@data;
            $count++;
        
    }
    
    $objREF{static} = "yes";
    $objREF{instream} = "$binString";
    $objREF{size} = "81";
    $objREF{end} = substr($binString, (((81 * 8) - (length(join('', @d
+ata)))) - 1));

    return \%objREF;
}

    if (@_){
        my $value = shift;
        my $bitstream = ${$objREF->{n_way}};
        
        substr($bitstream,0,1) = $value;    
        ${$objREF->{n_way}} = $bitstream;

        my $value = substr($bitstream, 0, 1);
        return $value;
    }
