Re:VMS was doing this in the 80's (Score 1)

I agree that VMS has a very high probability of being prior art on the patent. Within VAX/VMS Condition Handling was done using hardware instructions, but it certainly appears that Borland's approach is just a software implementation of this. For a good description of VMS Condition Handling see http://cs.felk.cvut.cz/vms73/v73/5841/5841pro_026. html#cond_handling_chap. Any other old VMS hands have comment?
