 Aside from dialogue, the script cites Michael Myers by name only  twice. In the opening scene, he is called a POV until he is revealed  at age 6. From the rest of the script on out he is referred to as a  "shape" until Laurie rips his mask off in the final scene (which he  never reapplies in the script). "The Shape", as credited in the  film, refers to when his face is masked or obscured.
