I'm a bit confused by this question. Does anyone know the answer?
My understanding is that a leading edge SLAT causes a SLOT (when deployed) which re-energizes the boundary layer...thus delaying stall. A non-moveable SLOT is a non-moveable aerodynamic design that causes the same effect. A split flap is for old timers...
