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").

I was wondering if somone knew the answer to this... is BATCH
supported on RT11 that is running TSX+? I know it's supported on RT11,
but I thought I saw somewhere that once you loaded TSX+ that you
couldn't run BATCH because of some conflict. Anyone know the straight
scoop on this?
Jerome Fine replies:
Under RT-11, BATCH is supported via the BA(X).SYS
device driver, as well as other hooks in the operating
system.
When TSX-PLUS is run, the Resident Monitor (RT11XM)
is completely replaced along with the Keyboard (KMON)
and the User Service Routine (USR). There are also
minor changes to some of the device drivers. Most
of the utility programs run as is without change. Since there is no BA.TSX device driver, you can't
run BATCH under TSX-PLUS. Part of the reason may
be that SL: (the RT-11 Single Line Editor - similar
to some of the stuff done by DOSKEY in DOS) is built
into TSX-PLUS rather than being a separate device
driver as in RT-11 which uses SL(X).SYS to perform
the functions. Since SL: and BA: can't run at the
same time in RT-11 and since SL: seems to be built
into TSX-PLUS, perhaps that is part of the reason
that BATCH is not supported .
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"
by TSX+.
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."
However, I doubt if
anyone knows the internals of both RT-11 and TSX-PLUS
sufficiently to comment.
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!!!
Does this information provide enough of an answer?
The answer Lyle suggested provides an alternative.
A command file can be used to run the job, but
the results might not be quite the same. On the
other hand, once BATCH is running under RT-11,
can you use the background job? Since I don't
use BATCH myself (anything I want done I am not
able to continue with anything else, so a command
file is sufficient), please let me know if KMON
is still available to the user? If only system
jobs can still be run, that is not very useful.
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).
