Re: st: how to create case id number

Stata does very little automatically.  One thing that it does do automatically is create a variable _n that contains the observation number or record number.  However, as soon as you sort or do something with the data set, these _ns will change.  So, to create the variable you seem to want, you'll want to use the generate command (usually abbreviated gen):

gen case_id = _n

I encourage you to play with Stata, including the very good help facilities.  You'll learn a lot quickly by simply diving in!  Good luck.
