And all the discussion of 800-byte blocks seems to miss the mark.
Shouldn't we be concerned, rather, with multiples of 172?

From existing data, we know that the usual space needed is more than 720 bytes, and no more than 800. The same data with LRECL=172 would occupy 860 byte blocks, taking more DASD space and more processing time and storage.
