   Sprintf0 - returns a String containing, fmt, after it has had its
              escape sequences translated.
*)

(*
   Sprintf1 - returns a String containing, fmt, together with
              encapsulated entity, w. It only formats the
              first %s or %d with n.
*)

PROCEDURE Sprintf1 (fmt: String; w: ARRAY OF BYTE) : String ;


(*
   Sprintf2 - returns a string, fmt, which has been formatted.
*)

(*
   Sprintf3 - returns a string, fmt, which has been formatted.
*)

   HandleEscape - translates \a, \b, \e, \f, \n, \r, \x[hex] \[octal]

                  \[any] into a single [any] character.
