   That's the penalty for speaking Delphi in a Pascal group.  For anything   
   involving strings, Delphi optimisation will be quite different from   
   Pascal optimisation, except (?) if you use type shortstring in a Delphi   
   early enough to handle them directly rather than through conversion to   
   some other type.

   Move will be slower (for short items) because of parameter-handling; and   
   3 bytes is not a convenient size, 4-byte aligned units being better.   
      
   You might do better to express your codons as 4-character strings such   
   as ' UUU' or as array [0..3] of char - or you might do worse.
