- Bomb IDs that may occur because of errors in Modula-2 programs:
- ID= 2 : Address Error (odd address, bad Pointer value)
- ID= 3 : illegal instruction trap
- ID= 4 : zero divide trap
- ID= 5 : check trap error (array bound error etc)
- ID= 6 : overflow trap
- ID= 7 : privilege violation trap
- ID= 9 : Line 1010 trap
- ID=10 : Line 1111 trap
- ID=11 : miscellaneous traps
-
- note: these errors occur most probably because of overwritten programs
