Using a while loop to keep a menu open

Hi I am making a script that allows to to choose from different buttons on a menu to get different pictures to pop up. I have a quick question:

Is there a way to keep the menu open so long as I do not click a certain button on it? I want to be able to open multiple things, but right now it closes me out after the first selection. I have an "Exit" button as "case 15." To do this I want to use a while loop. So I want the menu to stay open so while loop =/= case 15 stay open.

It's not evident how you're implementing the menu. If it's a GUIDE gui, it shouldn't have to be forced to stay open. It should remain there until the user explicitly closes it.
