Larry Osterman picks up the history ball and describes how those FILE_SHARE_* values came to be.
If you haven't read it yet, check out Chris Pratley's voluminous discourse on various aspects of the history of Word. It packs more history into one entry than I do all year. And that was a sequel! You can read the first half, too. In fact, the good stuff keeps on coming. just read it all.
