Very funny. I suggest (strongly, rather strongly) "When HARLIE was

typewriter based I/O devices such as the ones that IBM made who also
used magnetic storage since HARLIE had a bad habit of changing his own
memory to suit what he wanted it to be. However by using the printed
output, the two people involved could steer him back.
CP/67 was written in that era, you'll find people who write of getting TTY's for CP/67 (or was it CTSS?) terminals at home.
HARLIE is what Watson will be when he grows up.

Since HARLIE competed with IBM, that's doubtful.?

OTOH, I think our 2019 MINI Cooper S (a year old this month, ) with it's dedicated 4G cell connectivity is one upgrade away from being a charter member of SkyNet ... and it gets unattended OTA updates,? The navigation system display changed a month ago and WE didn't do anything.? (The Year of Darkness is only 10 years away ...)

You find the Release 2.0 one on his home page. My hardcopy of his
original text bears the signature.
I have the original, not autographed.? I saw release 2.0 in bookstores back in 1980's, but didn't buy it.? It seemed like it would be in stuck its (different) era like the original. Robert A. Heinlein considered some of revising some of his early stories after more science became known, but realized it would be endless and he passed on it.
Incidentally what's with the decidedly big house cat sitting next to you?

"What version of OS/2 are you running?"
Certain OS/2 binary system data files were known for getting easily corrupted and causing crashes.? IBM support was telling customers do a clean reinstall of OS/2 so often that it was a bad cliche.? IBM banned telling customers that, and so support had to hint at it. :-)

Thanks but I already read that. I was able use PF and PA keys on x3270 and Vista TN3270 that I purchased for $30.

?

When it displayed “HOLDING” or “MORE…”, I just press PA2 to continue (ctrl-home on Vista TN3270 or Alt-2 on x3270).

?

Also I use PA7 and PA8 to scroll text information up and down.

?

I learned new thing about dirname like ‘A’, ‘S’ and ‘Y’.? Same way like much “C:\”, “S:\”, etc.

?

Example: LIST fn fe fm where fn = filename, fe = file extension, fm = file mode or dirname

?

List * * A to see user directory

List * * D to see games directory

List * * S to see system directory

List * * Y to see installed software

Thanks. I did not know that VM/370 do not have XEDIT.? XEDIT appears in VM/SP Rel 5 or before so that I think.

?

I looked at ESA IO and S370 IO instructions on Hercules sources? Both IO mode can coexist together so that it is possible to rewrite CP (VM hypervisor) easy. ?I have to take a look on CP sources on VM six pack distro. Also can extend DAT management to allow paged memory space in 31-bit mode.

Well, licensed code is not needed.? So can port open-source MSYS into VM/370 for POSIX shell and implement BFS specification like unix filesystem. ?I am looking for BFS specifications. ??POSIX shell and BFS first appears in VM/ESA and later.

Timothy,

?

I am not sure when XEDIT appeared, SP1 I think or REXX . Whilst folks have written a screen mode editor and installed a portable REXX on VM//370 they don’t interact in the same way that XEDIT and REXX do on VM/SP which means many things don’t work.

?

Also note XA mode isn’t virtualizable in the same way that 370 mode is.? VM/370 relies on the fact that the Store PSW is a privileged instructions so that a user mode program can’t tell it’s a use mode program.

Some of the instructions introduced in XA mode expose the machines state back to a user mode program. This means you can’t use the same trick. XA mode also introduced a new instruction called “SIE” which stands for “Start Interpretive Execution”. This means tweaking VM for XA mode isn’t easy…. Much simpler to run LINUX barefoot..

A short VM/SP history summary:
  • VM/SP 1 (I think, I didn't show up until VM/SP 3).
    • IUCV
    • XEDIT
    • EXEC2
  • VM/SP 3
    • REXX
  • VM/SP 4
    • GCS
    • DIAG x'8C' (querying your console display size)?
  • VM/SP 5
    • Full Screen CMS
  • VM/SP 6
    • Shared File System (SFS)

Thus, the LCM+L 4361 running VM/SP 5 has all of the above except SFS.

I think the primary reason for GCS's existence was to support running VTAM natively on VM/SP; previously it had to be in a guest machine such as VS/1.

By VM/SP 4 IBM had a revised version of the RSCS Program Product running under GCS.? It also had TCP/IP (running on CMS). The 4361 doesn't have either installed (they do have the media) because of a lack of the associated hardware.

-ahd-

p.s. Insert my usual disclaimer: I do not work for and not speak for the LCM+L.

And the Internet turned fifty last week

 

Hello!
Read this and react:

"
Depending on how you look at it, the Internet turned 50 years old last
week (
) . On October 29, 1969, the first message was transmitted between two
of the four nodes that made up ARPANET, the Internet's predecessor
network. ARPANET was created after a million dollars earmarked for
ballistic missile defense was diverted from the Advanced Research
Projects Agency budget to research packet-switched networks. It's said
that ARPANET was designed to survive a nuclear war; there's plenty of
debate about whether that was a specific design goal, but if it was,
it certainly didn't look promising out of the gate, since the system
crashed after only two characters of the first message were sent. So
happy birthday, Internet, and congratulations: you're now old enough
to start getting junk mail from the AARP ( ) ."

Help with SMSG and RSCS message: NOT AUTHORIZED

 

Hi All!!

I'm trying to work with the VM/370 sixpack 1.3 Beta 3 and it looks like
a really nice piece of work! Thank's Dave Wade and everybody who put in
the work and made it available for us clueless folk :-)

I was able to set up a RSCS virtual machine. However, after I IPL'ed
RSCS and did a "SET SMSG ON". I disconnected and logged into the MAINT
account. I tried the following and this is what happened:

q n
RSCS???? - DSC, OPERATOR - 009, CMSBATCH - DSC, CPWATCH? - DSC
MAINT??? - 0C0
Ready; T=0.01/0.01 15:46:47
smsg rscs q sys
RSCS???? NOT RECEIVING; NOT AUTHORIZED
Ready(00057); T=0.01/0.01 15:47:12

I tried looking around for clues about why this is happening, but I
guess my Google fu has failed me. Anybody have a clue what I may be
doing wrong? I know more about MVS and am quite the newbie with VM :-)

Hi Bill,

There was some sort of misunderstanding between Dave and I and somehow
the VM/370 sixpack 1.3 Beta 3 download page ended up saying there were
RSCS updates included but they never actually got included.

The RSCS that comes with VM/370 is very limited and is not capable of
responding to SMSG commands. It only accepts commands on the RSCS
console.

I have some rough and ready updates for RSCS that can help with this if
you want to give them a try.

Regards,
Peter Coghlan.

Hi Peter,

I would be glad to give your updates a try. By any chance would this update include your work with TCPNJE? If so that would be awesome. I'm somewhat aware of the great work you have done is this area.

One of my longer term goals is to have vm/370, linux and the tk4- MVS systems all talking to each other. But I wanted to have at least a pair of vm/370 systems talking first.

Any assistance you could give me would be greatly appreciated.

As well as the ability to accept SMSG commands, I also have updates to enable
VM/370 RSCS to host NJE links (just about!). The latter co-operate with
TCPNJE devices which are part of Hercules and between them allow NJE links
to be carried over the internet.

Thanks, I was aware of funetnje. Found it on GitHub. I wanted to make a
few cosmetic changes to it, mostly where things install and where the
spool files and config files live. Unfortunately my laptop with the
changes I made were at least temporally lost as the hard drive failed.

As for MVS, I just hoped that I could at least use RSCS as a RJE
station. But that is for future investigation. I know th4- will do RJE
as I was able to get the rje80 program to connect and send a job and
receive its' printout. I just hope I could get RSCS to do the same.

I think several different people are all independently tweaking funetnje
to update it so there is probably a lot of duplicated effort going on :-(

I believe that setup can be made to work. However, some do not regard it
as not completely satisfactory because MVS is only able to interact with
nodes directly connected to it ie it cannot send files to distant nodes
on an NJE network.

Any assistance you could give me would be greatly appreciated.
I'll send you an email.
I've sent you a zip file of RSCS updates.

Re: Help with SMSG and RSCS message: NOT AUTHORIZED

 

Hi Bill

I am one of those people Peter mentioned ;-)

During the past weeks I created a proof of concept implementation of funetnje targeting at providing an "NJE helper" on the Hercules host that makes an MVS 3.8 system running on that host participate in an NJE network, without needing to make any modifications to JES2. It currently works quite well (RECFM F/FB, LRECL 80 only, by now) on Linux and MacOS hosts (others not yet, simply because I didn't adapt the source). In Peter's inofficial new EARN/Bitnet NJE network my online TK4- system participates as node CZHETH3C using this NJE helper POC. All who are interested can download the POC from? (do so at your own risk, this is a proof of concept, not a production software).
