..and there is the instance of the DOS 3.3 that was laid out on the
disk, while "HELLO" is the default suggested name - it may be
somehting else.


You can be sure by initializing the disk..

INIT HELLO,D1 or D2.. or just no ,D1 is the last drive used.

INIT  and that is the boot name. So INIT BYTE-ME and it will
boot and look for a  BASIC entry named BYTE-ME

.. or mine, lots of them were 'GOODBYE' just to be a renegade.

ProDOS, of course- as noted is the first entry of XXXX.SYSTEM in the
directory.

This order is the order in which things appear from a CAT or CATALOG
in BASIC. Not necessarily the order a particular utility might show
you. Some of them order by date, alpha, or other way..
