Point Distance Workaround?

Hi all,

I have a set of postcode centroids and I'm looking to create a table or matrix of distances to all other points in the dataset. I only have an ArcStandard licence, otherwise I'd have used the Point Distance tool and had my answers an hour ago. I've found some VBA scripts on ArcScripts but I'm using 10.1 now which makes VBA integration difficult, or so I've found.

I'm also fairly new to Python so please spell out any code if applicable.

Thanks,
DK
