- -- A string whose length is bounded by Max_Length. The bounded string is
- -- empty at initialization.

- procedure Append (X : in out Bounded_String; S : String);
- -- Append a character or a string to X. If the bounded string is full,
- -- extra characters are simply dropped.
-
- function To_String (X : Bounded_String) return String;
- function "+" (X : Bounded_String) return String renames To_String;
- -- Convert to a normal string
-
- procedure Append_Address (X : in out Bounded_String; A : Address);
- -- Append an address to X
-
- function Is_Full (X : Bounded_String) return Boolean;
- -- Return True iff X is full and any character or string will be dropped
- -- if appended.
