one more question.. I want to make an HoH from an array but don't know why when I use print Dumper it does not look like a HoH it looks more like HoA i would say... attached is what I got...

i want something like this:
my %data  =  {'15'=>{'MATH'=>'412'},'16'=>{'Thermo'=> '235'},'17'=>{'statics'=>'211'}, '18'=>{'design'=>'250'}}; I currently have this:
my %data  =  {'15'=>['MATH'=>'412'],'16'=>['Thermo'=> '235'],'17'=>['statics'=>'211'], '18'=>['design'=>'250']};


my $counter = $#newper+1;
   
   foreach my $check (sort @table){
      
      push(@{$data{$counter}},%$check);
   
   $counter++;
   
   }
 
my @table = ({'MATH'=>'412'},{'Thermo'=> '235'},{'statics'=>'211'}, {'design'=>'250'});

['MATH'=>'412']
is the same as
['MATH','412']

=> is like , except that it automatically treats the left side as a bareword so you don;t get a warning fot
[math=>'412']

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

since @table contains references, sort @table will sort by the stringified references, which would come out in order of its address in memory, which is not very meaningful, ad probably not what you wanted.

@{$data{$counter}} will autovivify $data{$counter} as an array
did you mean
$data{$counter}={%$check}
instead of
push(@{$data{$counter}},%$check)

What is the purpose of having a hash with sequential numeric keys instead of an array?
