Hi,
I wish to associate a list of coordinates with a list of zones. The zones take the following form - 
B1, B2, B3, BR4, I22, IJ1, IJ17....etc.
The coorinates take the form - 1:23,7:59. I was thinking of storing the coorinates as a four dim array - [a1,a2,b1,b2] = [1,23,7,59]. Each zone has a abritary number of coordinates associated with it, such as B1 = [11,21,3,59],[1,23,7,51],[9,2,11,9].

How would I declare a hash to store this type of data? I'd like to add the coordinates on the fly, something like - 

for($a1=0;$a1<60;$a1++){
  for($a2=0;$a2<60;$a2++){
    for($b1=0;$b1<60;$b1++){
      for($b2=0;$b2<60;$b2++){
         $zone = Get_zone_for_this_coordinate($a1,$a2,$b1,$b2)};
         Add_this_coordinate_to_the_hash_for_hash_member_$zone;
      }
    }
  }
}

How might I do this?
Thanks.
