what is happening here? (access types & discriminants...)

[dale@cs.rmit.edu.au (Dale Stanbrough)]

I've got the equivalent of the following code...




with ada.strings.unbounded; use ada.strings.unbounded;

package ua is
   type Unbounded_Array     is array  (Positive range <>) of Unbounded_String;
   type Unbounded_Array_Ptr is access Unbounded_Array;


  i_dont_understand : unbounded_Array_ptr (1..100);
end ua;


Not quite sure what the definition of i_dont_understand is doing...


Thanks,

Dale
