Yes, it is bunch of bits recorded on tape. And it seems there is no need
to support "mainframe CCW language", because it is VTS who writes on
(real) tape, not z/OS or any mainframe OS using VTS.
However the above is true now and it was true 5, 10, 15 or 20 years ago.
But VTS always had been us
It is what I understood from announcement, once tape drives will not connect
directly to z/OS channel but to VTS for destage.
VTS emulates 3490/3590 and can destage to any kind of tape, it is just a bunch
of bits to be recorded in tape.
