It makes the Pascal distinction between value and variable parameters useless, as effectively, _every_ object parameter becomes a variable parameter, even when passed by value. Now, how can you pass an object that's meant to be kept unaffected by anything happening in the procedure or function? Well, yes, you simply can't. > > And, you _cannot_ use this notation yourself for your self-declared > > pointer variables.

These '"life" functions' are just references to a table of predefined ones that are called indirectly if needed. Just as with objects - and thus a really unneccessary extension of an already well defined concept. -- -- (Weitergabe von Adressdaten, Telefonnummern u.ä. ohne Zustimmung nicht gestattet, ebenso Zusendung von Werbung oder ähnlichem) ----------------------------------------------------------- Mit freundlichen Grüßen, S.
