   @item @code{str_len()} returns the length of a string.
   @item @code{str_chr()} scans a string @var{str} from the @var{start}-th
   character and returns the position of the first occurrence
   of the first character of a string @var{c}. Note that the top of a string
   is the 0-th charater. It returns -1 if the character does not appear.
   @item @code{sub_str()} generates a substring of @var{str} containing
   characters from the @var{start}-th one to the @var{end}-th one.
