***********
di in r subinstr("not a good varname", " ", "_",.)

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?
