TNotifyEvent

var X, Y : TNotifyEvent;
begin
X := nil; { *1 }
Y := X; { *2 }

if X = nil then ; { *3 }
if X = Y then ; { *4 }
end.

The compiler doesn't accept *3 and *4. It does need a parameter ("Not enough actual parameters") because it tries to compile to run X. How can I do the tests in *3 and *4 ? I tried to convert to pointers but couldn't find it.

Thanks,
Fons.
