It is so for the Borland dialects, but not for others. There _are_ Pascal dialects that _do_ make use of the tag and even change the interpretation of the type accordingly, or that use separate storage areas for the tagged variants. The problem with this construct is that it was never clearly specified by the originators (incl. Prof. Wirth himself) how it was meant to be used and thus how it should be implemented. BTW, fpc does indeed store the tag value, if an identifier was specified along with the tag type for the record declaration. This might be useful at times to keep track of the data stored in the variant area. -- -- (Weitergabe von Adressdaten, Telefonnummern u.ä. ohne Zustimmung nicht gestattet, ebenso Zusendung von Werbung oder ähnlichem) ----------------------------------------------------------- Mit freundlichen Grüßen, S.
