   Store a string in allocated memory.   
   sc (string constant: a u)   
   : $!A   DUP ALLOCATE THROW  >R   
       R@ SWAP CMOVE   
       R> ;   
      
   It helps to have SIZE in the memory wordset:   
   sva (string variable stored ALLOCATE d)   
   : $@A   DUP SIZE ;   
      
   The proper mindset is that there are string variables,   
   (string areas where a string could be stored and changed)   
   and string constants, sc n where you are no supposed   
   to change the content of the string.
