Dear All:

Apologies, but it's getting late and my brain has shut down for the
evening :)

All I want to do is add a variable that counts the number of records
within each by group. For example I want to include the variable
"count" as follows:

patid drug count
1     A    1
2     S    1
3     B    1
3     F    2
4     O    1
5     W    1
6     A    1
6     C    2

I know it's a simple first. last. coding question, but any help would
be appreciated.

Thanks,

David.
