  6.         Declares DDE functions to simulate the DDEADS functions
  7.         in R12.  These functions are not fully implemented, they
  8.         are only used to show the usage of DDE classes.
  9.  
  10.         A fully implemented C version of DDEADS is provided.
  11.         This file is compiled as DDEADSPP.EXE.
  12.  
  13.     Function:
  14.  
  15.     (xload "ddeadspp")  
  16.     (ddedrawing) Poke current tables and entities to EXCEL.
