Since Rajiv wants to suppress data by person, the following should be used:

bysort Person: drop if Time > Event_Time

..Frank

I need to suppress these data as follows:  since the event occured for
person 1 at time 2 I want to drop all data pertaining to him for period 3
and keep data only for period 1 and 2.  Similarly for person 2, since the
event occured at time 1, I want to drop all data after this point and keep
data only for period 1.


* Does this do what you want?

drop if Time > Event_Time
