Charles has a hash function for type String; see the files:

charles-hash_string.ad[sb]

There's also a hash function for type Integer:

charles-hash_integer.ad[sb]

In your case, you have an integer key, so you can use the Hash_Integer
function already provided by Charles.  

Except for Hash_String and Hash_Integer, there are no "general-purpose"
hash functions, since writing a hash function often requires a modest
amount of tuning over expected inputs.
