Yes it is not necessary to use two instances - I had not tried sending the
Prompt (yes - the Dump Request) from the same screen as I was receiving- as
I imagined that MIDI-ox would be in a hung loop waiting to receive a manual
dump once that was initiated and therefore the same instance would not be
able to send the Dump Request.If the Dump Request is being sent from the
same instance - then I am unclear as to how MIDI-ox is then in a state of
"RX manual dump" on the same screen to ready it to pick up the requested
dump - which is why I was using two instances.

I believe you that you don't see the reason. Intuitively it makes
sense to me--midi-ox still needs a roundtrip midi flow for some readon. In
any case, I explained the testing procedures I used and reported the
results.
I remain convinced from my systematic testing that (1) there is no need to
use more than one instance of midi-ox to send sysex data dumps to the CZ and
(2) there is no need to use more than one instance of midi-ox to receive
sysex data dumps from the CZ.
Based on your experience, I assume you can also do it with two instances of
midi-ox. However, I think it should be clear that a person does not need to
use two instances.
If you (or anyone else) decides to try to replicate my procedures, I'd be
interested to know what the results are. There is always the possibility
that no matter how detailed I was, I may have left a step or two out (or
assumed too much background knowledge or experience on the part of others).

PS:
Just in case it isn't clear, what you are calling a PROMPT, is what I call a
sysex command, namely, what Casio calls Send Request 1. (See page 19 of
Casio's original "Guidebook for Midi (Nov. 1985).")
The very same instance of the version of midi-ox I used has a send/receive
command. So it sends what you are calling the PROMPT and also listens for
the reply.
In fact, you (or anyone else) can put 16 PROMPTS in the send area to request
16 CZ patches and the very same instance of midi-ox will receive 16 replies
from the CZ, one for each of the requests.
If it worked for me, I cannot see why it wouldn't work for others.

required to send a PROMPT to send the patch - the patch data is then picked
up by the RX instance.

(I generally like to run tests if I have the time to confirm that I am not
giving erroneous advice. Also, I usually learn stuff that I can use by
running the tests.)
