  History: see Word97 Hx.txt
  Version 2.2

  NB Event sinking will not work "as advertised" in Word 2000. I think this is because
   MS have finally implemented Word application events properly and my code goes out of its way
   to get round the bugs in version 97. If someone want to test the Word 2000 events (eg using
   the Delphi components) and tell me exactly what causes them to fire, I may be able to change
   the event code to work in Word 2000. I don't have Word 2000 so it's rather hard to test...

  NB If you wish to use Word 2000, make a compiler define for USE_WORD2K
   Either put the following in the interface of appropriate units or better still,
   use Project.Options.Conditional Defines to set this compiler define globally
    {$DEFINE USE_WORD2K}

  NB As far as I am aware, a program compiled "use"ing any of the type libraries
   should be able to talk to Word 97 and Word 2000.
   This is because Word 2000 continues to support the Word 97 interfaces.
   However, I would suggest you compile your program with the new Word2000.pas
   provided in the Delphi 5 update.
   If you define USE_WORD2K then my code will call the old version of some of the Word
   methods (eg AddOld rather than Add). This compiler directive simply tells my code which
   type library you are using - it will not use any new features found in Word 2000.
   If you wish to use the new features in Word 2000 (eg macro parameters),
   you can do so and cover yourself with an $IFDEF to make sure your code works
   for Word 97 users too (if you need to).

  If you make references to the following type libraries in other units, copy the series of $IFDEF's
