Early return

Control automatically returns from a function after its last sequenced expression is evaluated. However, you can also return explicitly using the return keyword:

-- Tells the user something on the hour

on notify user: for date

if (minutes of date) ≠ 0 then return false

alert "New hour!" message "It's now " & ((hours of date) as string) & ":00."

true

end

repeat while not (notify user for current date)

delay 60

end
