  3. * CXDemo    - Commodity Demo Program                                       *
  4. *                                                                              *
  5. * Written 1993 by Daniel Weber                                                 *
  6. *                                                                              *
  7. * This small demo program shows you how to use the commodity.r routines.       *
  8. * Don't look at this code (it's a mess), but use it as a reference.            *
  9. * Use the C= Exchange program to test it, and try to start it again while      *
  10. * one demo is already running...                                               *
  11. * Have fun! Daniel.                                                            *
