HandleEvents uses RunApplicationEventLoop() which IS Carbon Events. “FB Events” ( i.e. via ON DIALOG etc. ) are essentially synthesized from what Carbon Events provides. Without getting too technical here on the list, if you compile a program with FB5 it is using Carbon Events. Other comments by Deep regarding QuickDraw, pascal strings are accurate although pascal strings themselves aren’t deprecated many of the supporting functions are. Moving to CG and CF are clearly the right path for future goals ( such as app store inclusion etc. ). Brian S
