   All buffers generated by CREATE has a DOES> pointer that can be changed.   
   That makes CREATE not the fundamental building block it is suggested to be.   
   ciforth has DATA   
   that is in effect the familiar VARIABLE but without the allocation.   
   : BUFFER   DATA    CELLS ALLOCATE ;   
   : VARIABLE DATA     1 CELLS ALLOCATE ;   
      
   DATA is creating a header with DOVAR as its action   
      
   A proper building block would be   
   HEADER  ( name label -- dea)   
   Where the name is the created name and the label points to low level action.   
   dea is the "xt/nt" resulting. dea is a dictionary entry so that   
   other fields (data content, immediate flags etc.) can be filled in later.   
      
   DATA becomes   
       parse a name and pass a label dovar to HEADER leaving dea   
       fill in HERE as the low level data field in the dea   
       (Not to be confused by >BODY that makes only sense in the   
       context of CREATE DOES> )   
      
   Remember CDFLN (code data flags link name)
