I am not sure if it translate but in my film camera's the Auto mode does not allow alot of changes. But in Program you can adjust the apature up and down and the shutter will correspond. Example if the camera starts at f5.6 and s60 you can change that to f3.5 and s125. This is called flexible program where in auto if the camera say f5.6 and s60 thats what you get. In DSLR's I think Program also lets you change the ISO and not in Auto. But I am not 100% since I have not jumped onto the digital train. Hope this helps.
