If you look on amazon.com there are other more contemporary books, but I've
never read them so I can't recomend them.
I have, however, read Word 97 Macro & VBA Handbook ISBN: 0-7821-1962-X, and
I highly recomend it, if you have no programming experience. The first 140
pages teach you how to use all the built in functions of Word that most
people don't use. Then, the remaining 700 pages teach you VBA from the
ground up.
I suspect a few objects and properties have changed over the years, but the
principals are the same. I use Word 2000 and haven't found any discrepencies
between the book and Word 2000, so you should probably be able to get a good
understanding of how everything works.
