Dear Statalist users:

I would like to combine two variables in one:

The first variable represents the state: e.g. CA (California) or AZ (Arizona).
The second variable represents the countiy and includes numbers: 01,...

The combination of both variables finally states from which county the individual is from, e.g. CA 01 is county Alameda, AZ 01 is county Apache, etc. Does anyone know a trick how to combine both variables so that it identifies uniquely the county where the person is from?
Thanks a lot!!
Johannes
