Subject: A Count question

I have a following dataset with two variables: subject (Charecter)
parts
(numeric):

subject   parts
-------   -----
1001       1
1001       1
1001       2
2003       3
2003       4
2003       10

I need to count how many different values for the variable "part" by
subject is available.
the output should be as below:


subject   parts
-------   -----
1002       2
2003       3

Thanks a lot.
