I seem to remember seeing some source code for an auto folder program that installed a custom trap #2 which required that a custom trap #13 was installed. It looked for BIOS #5 (set exception vector) to see if it was setting the GEM critical error vector found at system variable $404. If the trap #2 was not the custom trap #2, then it reinstalled the custom trap #2. -- David P.
