Not beeing able to use the OO syntax is really a pain! (Even inside the LinkedList unit itself.) But it is all what we miss, I guess. One point for me precisely was to write it from scratch, without any higher-level OO structure (object, class). Explore the techniques and issues of writing OO-like code in a language that would not come equipped with such a framework. A side-question is also to avoid overloading code with a prebuilt OO layer, for efficiency (*). I take the opportunity to ask about the speed cost of using FreePascal's class-system vs plain Pascal. And the same about using objects vs plain records. I have no idea about this. Are there some data about this? Denis (*) Even more because in a while I intend to write a custom OO system (prototype-based). Building it on top FreePascal's class system makes a double OO layer, from client code(s point of view. PS: I have slightly changed the online code: * Replaced methods in correct order (for me), thank to one of you pointing me to "forward" :-) * List_new now accepts directly an optional array of startup elements, not a pointer to it (I discovered arrays can have a 'nil' default.) ________________________________ vit esse estrany ☣ spir.wikidot.com _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
