Yes - except that SETSIZ.COM is run (executing SETSIZ.SAV) as part of the
install process, and modifies the RT utility binaries to include the actual
amount of memory required for them to run under TSX+. (BTW, the utilities
work fine with RT-11 after the "patch").

SL can be removed from TSX as part of the install (TSGEN) process. However, as
you stated, a BA.TSX is not present and therefore "batch" is not even "seen"
The System Manager's Guide says "The following RT-11 device handlers are
unsupported under TSX-Plus: BA (resident batch handler), EL (error logging
pseudohandler), and PD (PDT-11/130/150 handler). The ethernet drivers, NC,
NQ, and NU are not supported. Also the IBSRQ function of the GPIB IEEE IB
handler is unsupported."

That is almost correct ;-)
I've been spending a fair amount of energy studying the internals based on the
TSX-Plus "Programmers Reference Manual", "System Manager's Guide" and the
"User's Reference Manual". I've also been asking a LOT of questions on the OS
from the person who architected TSX and ran the company who developed and
sold the product. I figure that when I release TSX-Plus, I'll essentially be
as close to "tech support" as we can have for a while - along with all the
folks who have been playing with licensed versions of the software for years.
Even though almost all of the source code was lost (I found some scattered
pieces on the development Fujitsu 2312 drive). I did pay do have all of the
TSX-Plus listings (4 boxes worth!) shipped to me here in California. I passed
them on to Al Kossow (bitsavers.org) so he could scan them and make them
available to the world (I have permission from the owner to do so). So at
some point we'll all have all of the "internals" :-)
In the meantime, the TSX-Plus manuals do describe in detail how to modify
DEC's handlers for operation under TSX-Plus - and a fair amount of detail on
TSX-Plus internals. The more I study, the more I'm impressed with this OS!!!

Since detached jobs, spooling and indirect command files are available under
TSX-Plus, my guess is that anything you could do with Batch under RT would be
"doable" under TSX-Plus (with some modification to the batch file).
