Sorry for my misinfo, but I didn't find anything about class variables in the docs (1.06), and I tried, in vain, to compile programs with class variables. I'm happy to learn that -St allows using class variables. It's a pity, though, that different keywords have to be used for class variables and class methods. By class properties, I mean properties that only access class members (class variables and class methods), and are accessible with the syntax: <classtype>.<propertyname>. When trying class methods, I found that the executable behaves strange: Invoking a class method with <classtype>.<method> works fine. But, invoking the class method with <classvar>.<method> is accepted by the compiler, but results in an exception when <classvar> is nil. Is that OK? thanks, anton tichawa. ---------- "Adas Methode war, wie sich zeigen wird, Tagträume in offenbar korrekte Berechnungen einzuweben."
