RoboFan,
You can easily do this by storing the reusable text in a
script file and attaching it to each topic in the help system. For
example, you might create a script file called global.js and add
the following to it:
level1 = "Whatever you want to say for this level.";
level2 = "Some text to write in for this level";
level3 = "This information in this topic is confidential. Do
not share with anyone outside of Company, Inc";
Then you'd link it to your topic files and write in the
required text as shown in the example below.
This is essentially the procedure that Peter describes in the
following page of his Web site:
http://www.grainge.org/pages/authoring/customising/terminology_1.htm
Notice that there are a few hoops you may need to jump
through if using this method in a compiled HTML Help (.chm) file,
as otherwise your users may get error messages when they print
topics to which the script file is attached.
