Hi,

I'm having some problems counting my data.


It's of the format:

Station Year Month Day observation
A  1901  6  1  2.4
B 1901 6 1 3.5
C 1901 8 2 2.5
.....
A 1910 6 1 2.6
B 1910 6 1 2.8
C 1910 8 1 9.4

Basically I'm looking to count by year, the number of unique stations
and the total number of observations. The key=station year month day is
unique.
 I can get each count seperately by using proc means and combining, but
is it possible to get it in one step?

Thanks,
Reeza
