Thanks Nick, it works fine!
I tried to understand what is going on in this program you wrote, but I cannot seem to find out where the variable names and labels are created - I guess I do not know enough of writing programs in Stata. What if I want to create the variable names "demograph_married_male" or label "married, male"?
Cheers, Peter
