Clip-4-Win is designed to help you get to grips with working
  with Microsoft's Windows, which provides a rather different
  environment to the DOS environment.  The differences are many
  and varied, not just as far as the user is concerned, but
  especially for the developer.
  
  The Windows Environment is covered in the section of that
  name, which includes sub-sections about Windows Terminology
  and about the event-driven nature of Windows.
  
  Be sure to read the section "Changes to Clipper Features", and
  the section "Clipper Add-on Libraries".
  
  Apart from the Function Reference section (and the Norton
  Guides), you will need to refer to the section "Compiling and
  Linking".
