st: Create a new variable based on some other variables

["Charles Man@CCR" <ccrman@cityu.edu.hk>]

Dear Statalisters,

If I want to create a new variable based on the values of a few other variables, how can I do that?

For instance,

Create B
If A1=1, then B=1
If A2=3, then B=2
If A3=8, then B=3

Can -gen- or -egen- or -recode- do this job?

Thanks,
Charles
