Given your address, that's probably overdue.

I hope not the latter. You might have situations justifying direct use
of STARTIO, but I can't conceive of a situation justifying bypassing
IOS and doing your own SSCH, nor would I expect sympathy from IBM when
(not if) things go tits up.

When you allocate a new dataset, you have access to the residual data
on the tracks that it contains. You're probably configured to
automatically write an EOF on the first track, but regardless there's
an exposure for everything else.
