That doesn't really change anything.  You could say:

declare
  Test1 : aliased constant String :=3D Result_Of_Function1;
  Test2 : aliased constant String :=3D Result_Of_Function2;
=2E..
begin



> =A0 =A0 =A0MyTreatment1(buffer.all, buffer.all'Size);

What are you trying to do here?  Why can't you simply declare
MyTreatment1 like this:

  procedure MyTreatment1 (S : String) is ...;

and then call it like this:

  MyTreatment1 (buffer.all);

No, Bob showed you what to do:

  ... new String'("this is my string");
