If you forget the override keyword after a function declaration, you may get abstract
errors. You can't call an abstract function directly. I'm not sure if this has
anything to do with it, but maybe Java's class ancestor/inheritance system is a bit
different causing you issues since you come from that background and have memorized
how to code classes that way.

Would need to see some sample code that is giving you the abstract error, though. I
just finished dealing with an "abstract error" and all I did was forget to place the
override keyword after the function declaration in the *derivative* class.

Just to add to the confusion: Tstrings is abstract.. so calling something like
TStrings.create isn't right but TStringList.create is okay.
