I am doing research work. I want to classify my context. I made a hash, the keys are ids and the values are descriptions. For the values part, the same case they use a couple of ways to descrip. like: if the value match 'ABC' and 'EDF' or match 'CDE' or match 'EDJ' and 'KIJ', then they will all belong to Case A group, I will put all those keys in one group. I made my hash: 
...;
@id=...;
foreach(@id){
   my @junkdesc=...;

   foreach(@junkdesc){
   my @data=split('..', $_);
   $desc = $data[2];
   }
   $myhash{$_}=$desc;
}

How to do that? Please help!!! and Thanks in advance!!!
