what no COMPARE AND SWAP? hardly a canonical listing of useful instructions :)


I mentioned the discussion of the IBM 360 and the lack of CAS to my friend the oldtimer (who cut his teeth on 360), he immediately replied that it was thankfully added, as R-ten-K stated, to the 370 ISA and it enabled a good implementation of optimistic concurrency in the RDBMS which we still develop today :)


I didn't say it was missing, I said without CAS it's hardly a useful set instructions.

That is right. You did not, R-ten-K did. You did instigate the discussion however.

I have some System 360 books... The more interesting is one is about the design decisions they made.. its about 2 or 3 inches thick... I love it when university libraries dump stuff into a sports hall and sells it for like $2. Just because no one has borrowed the book for a couple of decades.

Do you know the name of that book? I'd love to take a look at it.

It seems like it would cover in a lot more detail the things mentioned in "The Mythical Man Month" book.
