  19. * This is the include file which defines all the structures and constants
  20. * that can be used to build or intepret GOCA orders for the GPI
  21. *
  22. * ==========================================================================
  23. *
  24. * The orders fall into 4 categories :-
  25. *
  26. * 1) 1-byte orders
  27. *
  28. * 2) 2-byte orders    - second byte contains the value
  29. *
  30. * 3) Long orders      - second byte gives the order length, subsequent bytes
  31. *                       contain the values
  32. *
  33. * 4) Very long orders - third and fourth bytes gives the order length,
  34. *                       subsequent bytes contain the values
  35. *
