Subject:      Numbering Sub groups

Dear All:

Here is my data set:

ID   VarA
1     A
1     A
1     B
1     A
1     A
2     A
2     B
2     A
and so on.

I want to create and number the subgroups of VarA by the ID number.
So my data set should look like this:
ID   VarA   Group_N
1     A       1
1     A       2
1     B       1
1     A       3
1     A       4
2     A       1
2     B       1
2     A       2

Please help.
              Randy
