Cool, thanks. Yes, it seems to work.

BTW, here's another silly example just to demonstrate the subtyping of Oberon:


MODULE blah;
IMPORT O := Out;

TYPE object = RECORD END;
     Tchar   = RECORD (object) c: CHAR END;
     Tstring = RECORD (object) str: ARRAY 255 OF CHAR END;
     Tinteger= RECORD (object) i: LONGINT END;

VAR name: Tstring; number: Tinteger; grade: Tchar;

PROCEDURE write(VAR o: object);
BEGIN
  IF o IS Tchar THEN O.Char(27X); O.Char(o(Tchar).c); O.Char(27X)
  ELSIF o IS Tstring THEN O.Char(22X); O.String(o(Tstring).str); O.Char(22X);
  ELSIF o IS Tinteger THEN O.Int(o(Tinteger).i,1)
  ELSE O.Ln; O.String("dunno")
  END;
  O.Ln
END write;

BEGIN (* blah *)
  grade.c := "B"; number.i := 5150H; COPY("dosuser",name.str);

  write(name); write(number); write(grade);
END blah.
