Dear Statalist Experts

I need to create a dummy variable from the following variable "A" with top and bottom 20%.
Dummy = 1 if the variable A is in the top or bottom 20%. 0 otherwise.

That'll be great if I can create a separate variable with actual values with the same parameters.

Thank you so much.
