load =1al4
x = {altloc!=""}.altloc.all.pivot

Now we have an associative array with key:value pairs:

$ print x
{
  "A"  :  238
  "B"  :  244
  "C"  :  34
  "D"  :  12
 }
$ print x.type
hash

I can retrieve the value for key C:

$ print x..C
34

How do I retrieve a value for the nth element of the array without knowing the key?

$ print x.keys[3]
C

$ print x..x.keys[3]
(prints blank)

Thanks, Eric
