Abstract:

Doc-To-Help 2000 has a new 'fault tolerance' feature that forgives novice authors their Microsoft Word mistakes, including direct formatting and stretched bookmarks. These problems often cause corrupted cross-references as well as document-to-Help-system conversion problems. Doc-To-Help's automatic diagnostic and repair utilities now find these common errors and correct them automatically.
