> . qui bysort id (x): replace x=x[1]
Thanks Tim.  This is indeed better and it hadn't occured to me probably 
because I tend to not remember what order -sort- puts things in and so 
I try not to rely on the specific order (ascending or descending) if I 
can avoid it.  (I know I can just look it up or experiment, and I do 
when needed.)  Nevertheless, I think I will adopt this approach since 
it is one line long and clearer.  Thanks.
