Would this new system be compatable with all existing
programs that now still run on z/OS? I think you have to
have that. That's what makes z/OS such a great
platform. The program wrote 25 years ago still runs
today. Unless you maintain full compatability, you have
nothing. If you can't keep running all your old software,
you may as well go to windows or unix.
An even bigger problem for compatibility would be the
data files. If the native coding of U/OS is to be UTF-16,
I'd expect that all of the files would also have to be
UTF-16. None of the existing programs could read them.
Assembler programs would be much more difficult to
write without some major additions of instructions. Think
for instance, about MVC, ED, and TRT. Or, do you mean to
make a byte 16 bits? That would break *everything*.
Also, while storage is very cheap in comparison to
what it used to be, files would nearly double in size (as
would memory requirements). What would it cost do double
your DASD farm and your memory?
While I can admire the idea of UTF-16 as a native
encoding, I'm not sure you can get there from here. I
agree with Eric that if you can't run your old programs,
you wouldn't migrate to it; you'd run something else that
has a track record.
