 Read in r with type tc using v.  The packing of the data in
   the file is defined by v.from, the packing of the data in memory
   in v.to.  shape is the dimmensions of the reference, if it is
   an Open Array.  Otherwise, it is ignored.  Proper conversions are
   applied.  It is assumed that r has been properly allocated to
   handle the incoming data.  


PROCEDURE Write (v: ConvertPacking.WriteVisitor; r: REFANY; tc: TypeCode;
                from: RTPacking.T;  READONLY shape: ARRAY OF INTEGER; n: INTEGER)
    RAISES { Error, Wr.Failure, Thread.Alerted };

 Write r using v.  The data is writen in the local data format.
