Thanks so much for that detailed explanation and example code.  There were a
number of things I wasn't quite understanding about PET file I/O handling
and, more specifically, how one monitors status from BASIC.  As a result
I've been able to put my finger on why SuperPET OS-9 refuses to work when
the REL 'container' file (OS-9 volume) resides on my SSE Hardbox hard drive. 
Among other issues that I've already found and fixed, it turns out that the
Hardbox firmware is not flagging EOI when delivering the last byte of the
record!  As a result the OS-9 bootstrap loader never stops reading when it
accesses the initial record, eventually crashing the application.  This
tells me exactly where to start looking in the code.  Much appreciated.
