Your problem is a little hazy to me, and it would be good if you could provide a little example. I have often found -ssc d descsave- useful for extraction purposes...

> Betreff: st: Creating new variables from variable values
> Hi,
>
> I have a data set (European Social Survey) with several variables
> indicating the respondents' and parents' country of birth. The values for these
> string variables (which I know that I can convert) are mostly letters (some
> are numbers and I am not sure what they mean but I can set them to missing).
> There is no value label.
>
> The ESS uses a common letter system for countries (ISO 3166-1) and I have
> copied them into a Stata file by country. What I want to do is to edit
> that file and assign values by groups of countries (e.g., Nordic countries,
> English speaking countries, etc.) to get groups that fit a theoretical
> pattern (don't worry about this). The next step would be to sort by these
> numerical value labels (or values for a new variable to create new variables
> such as born in Nordic countries, born in English speaking countries, born in
> transition countries, etc.
>
> Now I know that I can do this by hand (e.g., gen bornsoutherneurope if
> cntbrtha == ES | cntbrtha == GR etc). But this would be a rather long and
> tedious process. Is there any way to take the country codes (now in a file
> with country name--which can be deleted and with a region code that I could
> add) and create new variables from it?

> Thanks,
