Ahem ... I have now discovered the reason why I could not import my object from a unit (there was no .o file!). Using "--automake" ensures that the .o file is created, and the object imports okay. However, the problem still exists with creating a descendant object. I can now (magically) create one (if the parent object is in a unit), however, if I try to create a new constructor, any call (inside the new constructor) to the ancestor constructor (e.g.., "Inherited Init") causes a GPF ! The parent object is now in a unit, but the descendant object is in the main program. Best regards, The Chief Dr Abimbola A.
