  4.    FAXCOPYE.C  A high-level CAS Toolkit function.
  5.  
  6.    This function allocates an Event Control structure, fills its fields with
  7.    those of the source structure, and returns a pointer to the copy.  All
  8.    the memory used by the copy is separate from that used by the source.
  9.  
  10.    INPUT:  A complete Event Control Structure as source for copy, and possibly
  11.             one for the copy as well.
  12.  
  13.    OUTPUT: A pointer to the copy of the source structure.
