Many thanks to RobDog888 for the answer to my earlier question.

Moving along the same lines, the project I'm working on was built with VS 2003 and Office 2003 installed locally. Most of the machines using this program will be Office 2003 based, however there are a few machines that are Office XP (2002) and Office 2000 based. I would like to add backward compatibility into my program to use the Word (Mail Merge) functions so that it is more or less version independent.

I've read some of the info on the Office XP PIA's on microsoft's site, but it's all written from the standpoint of upgrading, that is building an application for that version assuming you are using an older version.

I don't suppose someone could point me in the right direction?

Thanks in advance.
