   Also possible to add lines:   
      
   $ open/write f zz.txt   
   $ write f "X"   
   $ write f "X"   
   $ copy z.txt f   
   $ close f   
      
   or if one want VAR not VFC:   
      
   $ create zz.txt   
   $   
   $ open/append f zz.txt   
   $ write f "X"   
   $ write f "X"   
   $ copy z.txt f   
   $ close f
