Hi, 

I'm beginning to play with Ada, and run into this

with Ada.Text_IO; use Ada.Text_IO;
procedure Learn is
   subtype Alphabet is Character range 'A' .. 'Z';
begin
   Put_Line ("Learning Ada from " & Alphabet'First & " to " & Alphabet'Last);
end Learn;

Now I want to play a bit with the code ... and this fails and I don't get why and how to solve. 

Put_Line ("Learning Ada from " & Alphabet'First & " to " & Alphabet'Last-1);
or 
Put_Line ("Learning Ada from " & Alphabet'First & " to " & (Alphabet'Last-1));

Anyone more expirienced can explain this to my, please?
