It is what imposed the 3200 byte blocksize for input text. Meanwhile, some time before SDB was the ability to establish a blocksize and use that to get x storage (in the specified blocksize). This was, as I recall, something done to allow one to move between the 2314 and the 3350 disk drives without having to recalculate the space needed. Much of what has been carped about here was handled via various ISV products and finally IBM's DFP group got SMS out so that much of what you are complaining about could be handled by the system. But for all these complaints, I would much rather have the IBM system design than the designs of the BUNCH. And if you aren't old enough to know who they were, you won't understand.
