Betreff: st: Dropping string observations that have a sequence of characters


Dear Statalisters, 

I have a basic question, but which I still have not been able to solve. How
can you delete observations from a variable that contains strings that have
the letters "ur" for instance.

For example if the variable has the observations: "venus" "mercury" "mars"
"Jupiter" "saturn" "uranus" "Neptune". The how could I delete the
observations that contain the letters "ur", in this case "saturn" and
"uranus" ?

Thank you for your help,
George
