Hi all, I now have my code to count frequency of letters in a text but
I do not know how to read the command "enter" after I write my text.
What I have now is CTRL+Q but of course is not an elegant solution and
I know there is something easy but I cannot find it. Here below is my
code if someone could help me in that single question I would be
grateful. many thanks - sibyl

with Text_Io;
use Text_Io;

with Ada.Integer_Text_Io;
use Ada.Integer_Text_Io;

procedure Comptelettretest is

   Char , char2 : Character;
   cod: integer ;
   subtype Lettre is Integer range 20..255;
   type Freq_Lettre is array (Lettre) of Integer;
   Count : Freq_Lettre:= (others => 0);

begin

   Put_Line ("Entrer un text au choix et le terminer par 'CTRL/Q' et
'enter' ");
   loop
      Get(Char);

      --how to escape from this instruction, I want to hit enter and
have the list.
      exit when Char = ASCII.DC1;
      cod := CHARACTER'POS(CHAR);
      if cod in Lettre then
         Count(cod) := Count (cod) +1;
      end if;
   end loop;

New_Line;
   Put_Line("Frequence des lettres");
   New_Line;
   for cod in Lettre loop
      char2 := CHARACTER'VAL(cod);
      Put(char2);
      put(Count(cod));
      New_Line;
  end loop;
   
end Comptelettretest;
