MS Office Macros?

I’m looking for a good resource on writing macros (specifically for word) for office 07.

Technical articles don’t bother me, but everything I’ve found on my own is anything but technical.

I am specifically looking for material on both syntax and functions to be called. More specifically, I want to write a macro that will automate the process of saving a file in the old/new formats at the same time.

If anyone knows of a good place to start this little venture, I’ll thank you for your help.
