(* Modula-2 Halt Indices :
-11 : uninitialized interrupt vector
-10 : interrupt format error
-9 : Line 1111 emulator interrupt
-8 : Line 1010 emulator interrupt
-7 : Privilege Violation Trap
-6 : Arithmetic overflow (TRAPV Trap)
-5 : Index out of range (CHK Trap)
-4 : Zero Divide (ZerDivTrap)
-3 : Illegal Instruction Trap
-2 : Address Error Trap (Odd Address)
-1 : Bus Error Trap (Timeout)
0 : HALT called
1 : No RETURN from function
2 : CASE Index out of range
3 : Stack overflow
4 : Index or value out of range
5 : Arithmetic overflow (REAL)
6 : Improper workspace to NEWPROCESS
7 : Coroutine terminates
8 : Call to unimplemented SYSTEMX routine
*)
(*
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
