  16.  * Comments:
  17.  *    This file contains the definitions for SPX and IPX functions.
  18.  *    You will notice that in some of the definitions a "far" directive
  19.  *    is used.  This is a Microsoft C feature and I am not sure if other
  20.  *    C compilers allow such a declaration.  If you use a language that
  21.  *    does not support such a feature then you will have to use your
  22.  *    imagination to come up with another scheme of assigning addresses.
  23.  *    I do know that Lattice C has a function called "makepv" which may suit
  24.  *    your purposes in this area.
  25.  *
  26.  *    The definitions for the following structures are taken from the 
  27.  *    "Peer-to-Peer Communication Protocols" document.  See Developer's
  28.  *    Update" article for more information in obtaining this document.
