Trying to do it right - My script uses symbolic references. I'd like to know how change it so that I'm using hard references and can use 'use strict' without errors.

The program receives a hash of hashes and then attempts to update the hash after the record has read.


my %hash=('1'=>{one=>""}, '2'=>{two=>"",zwei=>"",dos=>""}, '3'=>{three
+=>"",tres=>""},'4'=>{four=>""},'5'=>{five=>""},6=>{six=>"",seis=>""},
+7=>{seven=>""});
my %subs;
my $href;
my $valCount=0;
my $recCount=0;

#get number of items
foreach my $item (keys %hash)
{
    print "count is " . (keys %{$hash{$item}}) .  "\n";
    $valCount+= (keys %{$hash{$item}});
}    
while($valCount > 0)
{    
    foreach my $id (sort keys %hash)
    {
        if(! exists $subs{$id})
        {
            $href=$hash{$id};
            foreach my $word (sort keys %$href)
            {
                next if(exists $$href{$word}{written});
                $valCount--;
                print "$id $word\n";
                $subs{$id}="";
                $href->{$word}={written=>1};
                last if((keys %{$hash{$id}}) > 1);
            }    
            $recCount++;
            if($recCount == 4)
            {
                $recCount=0;
                %subs=();
            }    
        }    
    }
}
