Arrgh - 0 means "ignore", what is not useful in most cases. A good description is in RBIL: http://www-2.cs.cmu.edu/afs/cs.cmu.edu/user/ralf/pub/WWW/files.html Quote: Values for critical error handler action code: 00h ignore error and continue processing request 01h retry operation 02h terminate program as though INT 21/AH=4Ch called (INT 20h for DOS 1.x) 03h fail system call in progress (DOS 3+) If "fail" is not allowed, the kernel defaults to "abort" (02).
