st: Something wrong with the -count- option in the -egen-?

[gjhxmu@sina.com]

I typed the following in the stata and found -count- option didn't work well.

Anything wrong?

clear
input x
1
2
3
5
.
end
egen y=count(x)
egen yy=count(x>2)
egen yyy=count(x==2)
l,noobs

    +------------------+
  | x   y   yy   yyy |
  |------------------|
  | 1   4    5     5 |
  | 2   4    5     5 |
  | 3   4    5     5 |
  | 5   4    5     5 |
  | .   4    5     5 |
  +------------------+


Thank you for any help!
