Please do not forget about the z/VM (CMS minidisk, SFS). So, we will
use this sentence as
Typically a "dataset" is MVS - z/OS, while a "file" is UNIX or z/VM.

Anyway, the dataset is a self-organized data on ECKD device with
different Count-Key's, meanwhile the file can be allocated on a
pre-formatted media. Exactly. And it one reason why z/OS does not work
with 9336 devices -- it can't drive by length of every FBA-block,
which  has fixed 512 bytes length. Yes, it is possible, in theory, but
too many z/OS programs require CKD/ECKD arch. Nobody will patch them.
