Yeah, when types are used all the \ needs to be turned into dots . plus all the separate functions would be best as methods of the Types (objects) now. Also a lot of my code was using buffers and lockbuffer etc. This would need to be converted to PixMap stuff although there is not much point because the 3D card does most of it. However, tons of the functions, such as the string handling, are totally generic and the menus, ini files, profiles etc are all good examples of how to make useful reuseable stuff (I hope).
