I tested this on a real FreeDos based notebook and it survived ;) But seriously, on more modern systems it doesnt do anything harmful anymore, while i have read that on older systems, you could provoke a system crash this way. Which then would create the interesting task of designing the CA in a way that it "avoids" the hazardous values. For now it seems that "anything goes", at least on all my semi-old and newer systems. DosBox Emulators literally dont care ;)
