If you need to know the number of unique values in the list here's a handy function:

Get_unique_values = Function( {in_list},

{Default Local},

tmp = [=> 0];

Insert Into( tmp, in_list );

tmp << get keys;

);

To use it, first compile the function, and then call it like this:

my_list = {"aa", "bb", "bb", "cc", "cc"};

print(get_unique_values(my_list);

{"aa", "bb", "cc"}
