Do I need to free these objects?

I'm using Delphi 1 16-bit to learn Pascal (don't laugh, it works fine, plus I can't afford a more recent version). I'm using a TList to hold object references for a simple address book. Each object is added to the TList like so:

DataList.Add(TAddrBookData.Create('Bob', '1 Mill St'));

Do I need to free the TAddrBookData objects myself? Or are they freed when TList.Free is run?

You need to free them yourself. Later versions come with a TObjectList, which is like a TList except it will only accept objects and it has the option to take ownership and free them for you automatically when the list is freed. But I don't believe TObjectList existed in Delphi 1, so you'll have to take care of it manually.

You will need to free (or FreeAndNil) those as well.

If you want to learn Object Pascal (Delphi) with a newer (and free) IDE try Lazarus as the free Turbo Delphi 2006 has been discontinued (what a bad move).
