Mladen:

Interrupt is a generic word and it can be used anywhere in a relative context. CPU hardware devices may have something called interrupt and I am least bothered about that while speaking in RAC related context. In simple terms SAST/BAST are system traps sent to the owning processes and it is like an interrupt to that process. If you think that INTERRUPT should only be used to CPU/hardware decice context, you may want to go ahead and use that only for that purposes..

What ever information I have provided is 100% correct in RAC related context. If some one else is relating that with VMS or punched cards then I can not help :)
