Function pointers

So if I got this right I could use it like this...

Local Integrate(timestep#)

Function IntegrateEuler(timestep#)
 'Do Euler integration
End Function

Function IntegrateRK2(timestep#)
 'Do RK2 integration
End Function

Function IntegrateRK4(timestep#)
 'Do RK4 integration
End Function

Select IntegrateMethod$
 Case "EULER"
  Integrate=IntegrateEuler
 Case "RK2"
  Integrate=IntegrateRK2
 Case "RK4"
  Integrate=IntegrateRK4
End Select


So whenever I call the Integrate function one of the three other functions are called depending on which of those I set the Function pointer to?
