You can't remove characters from a string. This sounds like a 
limitation, but it is simply asking too much from the "String" type.


Ways around this problem are...

   Construct a brand new string. E.g.

      New_String : String := Old_String (1..4) & Old_String (5..Last);

   You can't however do...

      Old_String := Old_String (1..4) & Old_String (5..Last);



   Use a different type,such as...

      Ada.Strings.Unbounded.Unbounded_String
