"I totally disagree with this. My view of Ada strings is that they are
 a higher level construct than C style strings. I believe at least some
 Ada implementations on top of Unix simply use many of the standard C
 library's string functions under the hood. I may be wrong but isn't a
 null-terminated string a valid representation of an Ada string?"


Yes, the Ada string could have an Ascii.Nul at the end of it, so long
as it never appeared in the array. However it still would be of no use
to represent C style strings. For example...

   A : String (1..10);
   Last : Integer;

   Get_Line (A, Last);


If Last is 5, then don't expect a \0 at position 6! (there may be one
at position 11 however).
