  3. //      the TUI libraries of the ObjectEase package. To compile and run this
  4. //      program create a project file including the files TUI30.LIB
  5. //      (use TUI40.LIB if you are using Borland C++ version 4.0) and
  6. //      TUIDEMO.CPP. Make sure that the files in the project are located where
  7. //      the project says they are. You may also need to modify the path to
  8. //      TUI.H in the #includes portion of this file.
