It's not allowed in Delphi in case of a var/out parameter. It's allowed in both FPC and Delphi in case of a value/const parameter. > The other issue I have is passing a property value via a var or const > parameter.

No, it is not allowed by Delphi (at least not passing a property to a var-parameter; passing it to a const parameter is allowed by both FPC and Delphi).
