Re: Antwort: st: detect unique values of onevariable into a new variable

[Robert Budras <budras@wzb.eu>]

I used the term "unique values" because STATA uses it when you type 
"codebook country". I don't remember the english word for 
"Variablen-Ausprägung", so i could not describe it better as in this 
example. Maybe you do?

Thank you for your time.
