Just use the normal string functions, then:
***********

Thanks. This would be exactly what i am looking for. But it seems like this
command was introduced in Stata 11 and i am stil working with Stata 10. Can
i download this function somehow, so i can use it in Stata 10? Or is there a
similar function?
