Hi,

Thanks for the advice... I restructured the code base on your observations... A question would be what happens to an array that is being used as a temporary container within a subroutine...

sub foo{
 
 my @this_array;
 my %this_hash;

 foreach....{

    push(@this_array, $something);
    $this_hash{$key} = \@this_array;
    
    #reset this_array for some other operation    
    @this_array=();

    $key = $next_key;
    $something = $some_other_thing;
 }

return(\%this_hash);
}

I was wondering if the hash that is returned by this subroutine will map all keys but the last one to NULL objects. This is because each time the array reference is stored in the hash, it is null-ed thereafter, and therefore the stored array references are now pointing to a NULL objects.. What would be the proper way to use an array as a temporary container ??
