If you just need a quick answer I would do this:


* read the first file:
use nfhs92
*create a dummy indicator variable:
gen x = 1
* add the data from second round:
append using nfhs98

* show list of variables:
describe

All variables comming after x were only in the second round in the list.
To see variables only in the first round just reverse :

* read the first file:
use nfhs98
*create a dummy indicator variable:
gen x = 1
* add the data from second round:
append using nfhs92

* show list of variables:
d
