The superconducting and normal transport in a semiconductor-coupled Josephson junction with a submicron split gate electrode has been studied. The maximum supercurrent I~ and the conductance show step-wise changes as a function of gate voltage Vg. This is evidence that I¢ is quantized in the superco
