There's only one event loop in VFP and it's the READ EVENT. VFP stays in the READ EVENT until it encounter a CLEAR EVENT.

So, in your main PRG, you call your menu and issue a READ EVENT. The user can then select options that bring up forms and switch between them freely. Assuming that you have an option in the menu called "Exit", you place a CLEAR EVENT in this menu command to get out of the application.
