Dear h390-vm followers, Till Winkler is currently conducting a survey on the usage of REXX. If you are using REXX, please participate and forward this link: https://rexxcommunity.limesurvey.net/418844?lang=en The results will be presented on the REXX symposium in Vienna in May. Thank you & best regards Mike

Did this by accident, and pulled up an old URL for https://publibz.boulder.ibm.com/epubs/pdf/ifc5g101.pdf and it actually pulled the manual into my web browser. So if you have URLs in your history, you still might be able to retrieve the manual. Too bad I don't have a complete dump of URLs to the documents. ... Mark S.

Hi All, I guess this question probably comes up a lot, but here we go again. :) I wondered if anyone had a good source for VM/ESA era manuals they could point me to? I've looked on Bitsavers but there doesn't seem to be much. I'm mostly interested in ESA because it seems both relatively easy to run on Hercules and likely to have manuals in original electronic format. The latter is particularly helpful for me as a totally blind user. OCR is not ideal. I know a lot of things used to be available from IBM, but they seem to move around a lot or vanishh without much fanfare. I'm particularly looking for electronic copies of any tutorial material, the general information manuals, concepts, and so on. I'm very new to mainframes as a hobby, though have a slight acquaintance with MVS and its ilk. Thanks much :) Best, Zack. P.S. I did find a thread earlier which linked to a giant Internet Archive directory, but that interface is absurd and I have no idea how to find anything in particular using the big table. -- Zachary Kline zkline@...

This may be a dumb question, but I couldn't find anything helpful after searching here in groups and generally on the web. I'm wanting to rebuild my first serious shop in my home: VM hosting DOS/VS. I see that there are Hercules Aethra and SDL Hercules versions. Is there any reason to prefer one over the other for running VMCE? From my reading a while back, MacOS security is a pain in the butt for Hercules and some other software. While I'm a Mac guy these days, I have old but Windows 11 capable Intel boxes and a few of the various Pi boards, including a 4, available. Are Pis sufficient for VM and possibly DOSVS? Thanks.

Hi folks! If you don't know what it stands for, you are only an acronym behind me: Interactive Problem Control System. Did anyone ever use IPCS? Does anyone still use IPCS? Do we need IPCS? ... Mark S.

It's taken me a while to get this done, but I have created two EXECs. One for the access order for RSCS, RSCS1, or RSCSTST userids, and a second one to assemble the code, with or without Peter's modifications, and build the RSCS module to IPL. I have also included templates for the four COPY files which users use for control of their RSCS system: AXSLINKS COPY, AXSROUTE COPY, LAXLINES COPY, and TAGQUEUE COPY. Anyone having gone through this process, I would appreciate suggestions to improve this, as I would like to add it to the VM/370 CE distribution. Anyone wanting to try installing, I would appreciate knowing what isn't clear, could be better or easier to use. As a side note: The first EXEC can be called from VMSETUP EXEC, if you add 'EXEC RSCSACC RSCS"" under the -RSCS label. You may wish to comment out the ACCESS commands listed there. ... Mark S.

Hi I am new to this group. Let me please provide a bit of background why I am making this post. At my first IT job in 1999 there was an IBM 9221 running VM/ESA and on top of that VSE/ESA. My involvement with that machine was (unfortunately) very sporadic, I had to look after other tech. I got very basic training on the machine, enabling me to do some simple things ('v net, act' and stuff like that). Unfortunately I forgot most of what I knew back then over the last 25 years due to not being involved with mainframes professionally. While I do play with mainframe tech in my spare time a bit, I cannot claim any in-depth knowledge. One thing that was explained to me back then was very impressive to me and stuck in my mind. > You can install VM on top of VM My knee-jerk question to my instructor back then was: > How deep can you go? He didn't know. Ever since, I have an idea in my head that comes back occasionally. Can you install VM 'recursively'? What I mean by that is the following: Can you prepare an IPL-able VM tape that does the following: * IPL (obviously) * without user interaction: * Some arithmetic to assess suitable values for the next step like available memory (storage) and available DASD space * create the necessary infrastructure to run a VM guest (user account, minidisk, etc.) with the pre-computed values from the last step * IPL the same tape that was used originally for the 'bare-metal' installation inside the just created VM * Configure the guest system so that it can be reached from the outside via a 3270 session or some such This process is supposed to run as unattended as possible, continuing until some inherent nesting limitation of VM is reached or a required resource like storage or DASD space is exhausted. I am lacking the experience with VM to assess whether this is possible at all or if perhaps it is possible in principle but only with later versions of VM than VM/370 or something like that. Anyways, I would be interested in the opinion of people on this mailing list regarding this topic. Perhaps you'll tell me this is a stupid idea, but hey ho. -Alex

Hi there! Does anyone have experience with 1-2-3? -- VM/370 CE V1R1.2, Hercules on macOS

rexxtry REXX interpreter running (CMS bREXX 1.0.1 Jul 5 2022) Enter any valid REXX instruction... type EXIT to quit.

https://www.softwarepreservation.org/projects/BCPL/index.html#IBM says "... [Martin Richards] was on a sabbatical at IBM Research in the early '70s, and I succeeded him in being the 'keeper of the keys' for his port of BCPL to VM/CMS. He had left everything in perfect order for me to take over. I continued to use this BCPL until I left IBM in 1993 (20 years, pretty good record for durability). I built a theorem prover (for Effigy [symbolic execution] headed by Jim King) in a personally modified BCPL. ..." [Jerry Archibald, squeak-dev list, June 2000] -- VM/370 CE V1R1.2, Hercules on macOS

Here I am again to ask one last thing (I hope). From what I understand, when you want to move a program to minidisk MNT19E 19E Y/S to make it available to all other users, you have to (re)save the CMS system. So: 1) acc 19E z, to make it available for writing 2) copyfile my program a = = z 3) read the MAINT MEMO B and 3.1) vmsetup cms 3.2) cp define stor 16m 3.3) ipl 190 clear 3.4) savesys cms 4) shutdown and reipl 5) with any user after logon I get: DMSFRE161T INVALID DMSFRET CALL FROM F87AE8, ERROR NUMBER 5. DMSFRE164T LOW-CORE NUCLEUS STORAGE POINTERS DESTROYED (INTERNAL ERROR CODE 5) RE-IPL CMS. DMSFRE165T CHAIN HEADER AT 0036F0: 0001EC20 0000000B 000011B8 10F00200. CP ENTERED; DISABLED WAIT PSW '00020000 00F812B6' quite nasty and unfriendly... I also tried the same things with a copy of VM/370 CE v1r1.2 just downloaded and therefore not "screwed" by me previously. The result was the same. Any advice is welcome, thanks! Marco

Was the following mod installed into VM/370 CE? M0071V00RESLIB-- CMS Nucleus Resident Library. RESLIB is a CMS transient area program that allows a user to define commands which will be treated as nucleus resident by CMS. These commands may be new or replacements for CMS supplied user and transient area commands. RESLIB also allows the allocation of storage resident work areas which are not released between executions of commands. The location of work areas and commands can be determined by calling RESLIB with an associated area identifier. Common problems eliminated by RESLIB are: 1) CMS transient area contention, 2) lack of concurrent execution capability, and 3) lack of permanent global communication areas. RESLIB is compatible with all releases of CMS.--Andy Hanushevsky, Cornell University, Ithaca, New York, March 6, 1980. NUMBER OF BLOCKS REQUIRED: 0000044 ... Mark S.

Hello, could you please explain to a person who knows very little about VM/CMS (that's me, the person!) what in VM/370 CE allows to bypass the change TOD request and the start type warm|ckpt|... ? If it's too long to write here could you direct me to the right documentation? Thanks Marco

bREXX Release 1.1.0 for CMS on VM/370 is now available at https://github.com/RossPatterson/CMS-370-BREXX/releases/tag/v1.1.0. There are no new known bugs and no changes to code since the last beta. There were some changes to HELP files and documentation. As noted before, there have been a lot of hands in making bREXX what it is today, mine are merely the most recent. The installation instructions are in the README.md file, and should come as no surprise to folks who've installed bREXX before, or who've suffered through my thousand-line beta emails :-) Ross

Is there a reason the REPEAT command in the legacy editor (EDIT) was deleted by HRC342DS?? Does anyone have a good work around to accomplish the REPEAT/OVERLAY combo?? It does not appear that EE has any OVERLAY command cheers, William
