> How does Ada do memory map files? Can you give me a few small, but easy to read, programs showing the various aspects of using memory map files in Ada?

If I understood you well, you are referring to those Linux memory areas mapped into files under the OS. If so, you can treat them as usual files, eg

   with Text_IO;
   with Ada.Exceptions;
   ...
   declare
      Full_Name : constant String := "/etc/somefile";
      Curr_File : Text_IO.File_Type;
      Cmd : constant String := "5";
   begin
      Text_IO.Open (Curr_File, Text_IO.Out_File, Full_Name);
      Text_IO.Put_Line (Curr_File, Cmd);
      Text_IO.Close (Curr_File);
   exception
      when The_Error : others =>
         Text_IO.Put_Line("!!! "&Ada.Exceptions.Exception_Information (The_Error));
   end;
