st: Smallest observation

I am trying to create an index for each individual in an 
unbalanced panel. The index should take the value 0 for the 
first time series observation for the individual and 1 for 
all other values.

My problem is that I can't find the right syntax to replace 
the index with 0 if this is the first time series 
observation. How do I refer to the smallest observation in a 
conditional statement?

gen s = 1
bysort indiv: rep s = 0 if year == smallest(year)?
