Hi! I have a question concerning the use of units. Consider this example: (*****************) (** Queue.pas **) (*****************) unit Queue; interface function isEmpty : boolean; {..} implementation {..} begin {..} end. { Queue } (**************) (* Test.pas *) (**************) uses Queue; begin {..} if Queue.empty then writeln('Queue is empty!'); {..} end. { Test } I expected to be able to use a "Queue." qualifier in front of the empty call in the test routine. But the compiler complains about an undeclared symbol Queue. Is this a bug or a feature? If the latter, how am I supposed to differentiate between the empty function of an Queue and a Stack, if not by using Queue.empty / Stack.empty? Regards, Marc
