Arcview 10.0 Cannot create Polygon with hole in Python. Impossible????

Kim Ollivier a couple of years ago gave example Python code to create a polygon with a hole in it. This involved a null point between the outer and inner rings of data.

His particular example works, but when I try to input my realworld xy coords using the exact same methodology, I get the null point interpreted as a valid point at the x,y origin (0,0), which in UTM zone 31 is on the Equator, not correct.

Cannot use Erase(analysis), you need ArcInfo for that.

Anyone with any constructive advice to get round this particular brick wall, greatly appreciated.
