Well, it seems I can *save* a tokenized .BA from VirutalT "File" menu,
it's just the load doesn't work. But I can then load it from TS-DOS.
I can see in the VirtualT "TPDD Server Log" monitor window that TS-DOS
is in fact sending a CLOSE file opcode, and the C printf statement I
added in VirtualT says it is closing the file.
Now I would need a large .BA file for the NEC to be able to test with.

Yeah, I just tried it. There must be some issue with the
addresses of the system pointers or something.
I'm looking into this now, along with why NADSBox doesn't close
the file.

Correct. Here's the results of both scenarios, using NEC
emulation mode in VirtualT:
* When you attempt to load an ASCII BASIC program that is
"improperly" named as a ".BA" file, the NEC emulation mode just
hangs, and upon a Reset, you get a cold start. But this all
makes sense; due to lack of an NEC tokenizer, who knows what
VirtualT is trying to do.
* When you attempt to load a tokenized BASIC program that is
properly named as a .BA file, you get "Ill formed BASIC file".
This hasn't ever made sense to me as it could be treated as a
binary file.

Umm. Good point. I'm not sure why you couldn't actually.
Have you tried it and it doesn't work?

By the way, I actually have always been puzzled by why I
can't directly load a tokenized .BA file. It makes sense
that a lack of an NEC tokenizer would prevent the loading of
an ASCII version of a BASIC file which erroneously has the
".BA" extension, but I would have thought that loading a
tokenized .BA file wouldn't be much different than loading a
.CO file -- just a direct copy into memory.
Please enlighten me! :-)

I can use the intrinsic Load & Save functions in the
menu for .DO and .CO files, but I can't use the Load
option for .BA files due to the dreaded "Ill formed
BASIC file". (Lack of an NEC tokenizer, methinks.)
The Save to HD option does work for .BA files, but since
I have to jump into TS-DOS in order to load a .BA
properly, I'm just accustomed to using one interface
(TS-DOS) for file operations just as a matter of practice.

Of course I need to ask the question that hasn't
been asked yet:
Why go to all the trouble of trying to save off a
file from VirtualT to the host using TS-DOS and the
virtual NADSBox emulation? Why not just use the
"File -> Save to HD" menu option?

I cant test this. It is entirely internal.
From what I read you have
Virtual T NEC, with TSDOS
Chatting with
Virtual Nadsbox
Using internal connection.
If you could show that real NEC has this issue then
I am all set to snoop it.
You could use laddieAlpha as a client for example.

Happy to set up and capture traces

Yeah, that's interesting. Suppose we could
"sniff" what TS-DOS is doing, as this is
100% repeatable. In my case, every test
I've done results in the file handle not
being closed, so it must never be sending
the opcode. That just seems very weird to
me, though.

Which would be a bug in TSDOS. Which
either would have to be fixed there or
we close the file after a timeout or
some other TPDD command can be used as
an indication the file is no longer
being written. Like if the directory
starts being enumerated.
