Hello Wise Monks,

I am trying to sort a hash ref by the date field old_file in the ref. Below is a Data::Dumper of one of the fields in the ref. I have done some reading and googling on sorting hash refs and it is all very confusing to me. Still not even sure if it is possible to sort by date. I'm still pretty new to perl. Any code snippets or directions to some good reading material would be very much appreciatated.

** Edit ** Found the answer between not accessing the hash ref correctly and not being able to sort hashes without proper modules. The answer lied (layed?) in doing the sort with my print. Code to follow. 
foreach my $key (sort { $patients->{$a}->{old_file} cmp $patients->{$b
+}->{old_file} }
   (keys %{$patients})) {
      # print ...
}

Big thank you to all the monks that replied. Never ceases to amaze me the level of help I get here.
