Sorry Florian, but I need to correct you here:

=== source begin ===

program stringtest;

{$mode objfpc}

procedure TestShort(var aStr: ShortString);
begin

end;

procedure TestAnsi(var aStr: AnsiString);
begin

end;

var
   s: String;
begin
   s := 'Hello World';
   TestAnsi(s);
end.

=== source end ===

=== console begin ===
