I distinctly remember using a product called SPM (Source Program Maintenance?) when I worked in a DOS/VS Rel 34 shop between 1977 and 1979. It was a full-screen 3270 editor, similar to SPF. I don't think I've ever seen it mentioned here. Does anyone have any info or fills? I sort of doubt that it's available but it never hurts to ask. Shawn Goodin

Does anyone have the DOS/VS R34 source files or know where to get them?

Hello everybody I know that my questions may be stupid but .. 1. How to remove (delete) BSAM dataset from DASD? In MVS I just use DISP=DELETE and IEFBR14, but how to remove sequenced dataset, previously allocated with DLBL and EXTENTs in JCL? 2. If I define DLBL and EXTENTs in JCL, but phase exuting in HOB STEP not touch (open, write) the file - will any extend will be allocated and enty in VTOC created? 3. If I have 2 extents defined, and program write data only for one extend (small record) will second extent will be allocated? I have strange observation and could not find the answers in available documentation Thanks Piotr P.S Sorry for my unfinished previous message, I've incidentally press the enter.

I worked on DOS/VS systems back in the mid- to late 1970's. While DOS/VS has some extent protections as mentioned, actual management of space on volumes is manually performed. This was usually managed by the system programmer's. The sysprog (usually only one) had to know what was where. Areas for each partition were reserved for work files. These were usually the same area on separate volumes of the same DASD type and attached to the different partitions by means of the same LU number. That would allow a programmer to have his batch programs jobs run in any of partitions with the same JCL. And while a VTOC entry can be removed, its data on the volume remains until physically overwritten, eventually. Of course, with Hercules it is extremely easy to add physical volumes to the configuration. But not quite so easy to add them to the DOS/VS Supervisor. That requires a new assembly. Like others, I am sure I forgot a lot of details since then. But the amount of human work to manage the DOS/VS system was significant. With just a single user, that is not as complicated as it sounds. I would encourage you to understand exactly how the system is set up. If you already do understand that, wonderful. If not do so. The acts of learning this information will itself educate you. DOS/VS is dumb. You are the smart one. Those who have worked with DOS/VS system you have certainly were smart. So some of what I refer to may already be inherent in the system. Still you need to understand it. WATCH THE OPERATOR CONSOLE. It will save you! Or KILL you. I worked in a shop where the operators did not understand the console or the messages. Shop was new to DOS/VS. When an operator's message came up they would just hit enter. That was hell! ENTER is in many cases NOT the right response. Harold Grovesteeen On 1/23/24 14:34, Piotr Kolasiński wrote:

I am trying to find complete source distribution for POWER II. Sadly the AWS file that we have seems to be missing at least A.POWERPRT, A.POWERPUN, A.POWERRDR, and A.POWERCOM which is the meat of POWER II. This would be for use under DOS/360. Any leads appreciated!

Hello everyone, I have been trying to run this very simple Hello World assembler program on George Shedlock 5-pack and the execution fails: PRINT ON,GEN,DATA HELLO START 0 BALR 12,0 USING *,12 OPEN PRINTER PUT PRINTER,$HELLO CLOSE PRINTER EOJ PRINTER DTFPR X BLKSIZE=81, X CTLCHR=ASA, X DEVADDR=SYSLST, X IOAREA1=PRTIO1, X IOAREA2=PRTIO2, X WORKA=YES LTORG * PRTIO1 DS CL81 PRTIO2 DS CL81 $HELLO DS 0CL81 DC C'1' DC CL15'Hello, World!

Where is the missing module? Or is the problem somewhere else? Rene FERLAND, Montreal

Looking at Professor Ferland's supervisor build from the Moshix M92 video, I see that there are additional unit record devices defined. I have a sockdev reader defined in my hercules config at x'02c', running the $$a$sup1 supervisor in the Shedlock 5 pack. Submitting a job to that reader does not seem to do anything, until I did a PSTART RDR,02C. If I IPL the Beaulieu system (using the $$a$supt supervisor), I can submit jobs to the reader at x'02c' just fine without manually issuing a PSTART. Looking at GC33-5403-1 DOS/VS Power/VS Installation and Operations (Sept 74), there are probably a PSTART for the reader at 02C in the autostart deck on the Beaulieu system. How does a novice change the AUTOSTART deck?

So far, I've discovered the FFORTRAN and PL/I Compilers on the Shedlock system. Haven't tried COBOL yet. I'll probably end up just making a new supervisor with everything set up for 2314 work files. In Professor Ferland's videos, I thought I heard that RPG could be installed, as well as higher level compilers for the other languages. Can anyone point this novice in the correct direction for getting those installed?

I'm wanting to get a DOS360 or DOS/VS (preferably) running. I'm looking for something that I can just do compile and run for PL/I, Cobol, and (hopefully) FORTRAN. I grabbed the dosvs5pack-v1r0m1*.zip files from the yahoo groups archives, and got it running (had to adjust the configuration for case-sensitivity, I host on Linux). Apparently it was put together by Michel Beaulieu. I see references to a 5-pack by Shedlock. Are they the same? If not, which is preferable for my load-and-go scenarios? (and where do I find the latter?).

Hi folks. Of all the languages around in this Mainframe work, Cobol is the only one I played with a little in the past with OpenCobolIDE (although I find Fortran not that hostile :-) ... But here I'm struggling because at the stacked principles that have to be all right in order for a JOB to work. Does someone know about some fundamental/basic examples of DOS/VS COBOL JOBs to start to play with? I've not found even the classic Hello World sample to check whether fcobol wakes up. Thank you very much in advance. Cheers.

Been working on VTAM under DOS/VS. Reading all the notes, emails, etc, I have collected over time I have got VTAM up and running under DOS/VS. Does do anything, as I have no appl that will run under it. A bunch of questions about it,that I have not figured out yet. ex: Do you run VTAM under Power yes/no..... I have tried to run it at a higher priority than power, but not sure about it. Numerous other questions, but one at a time... The code can be found at github.com/tchandler48/DOS5PEXT along with the documentation in the HOWTO pdf..... Any help, comments, etc, will be greatly appreciated.... Thank you Tom c

Hello Everyone! I know this may sound strange, but when you're trying to delve into the history of computer technologies, the earliest version of a program can be much more valuable than the latest one. In 1958, FORTRAN II was released. Is there a version of it available for DOS360? What is the earliest version of FORTRAN that is accessible for Hercules? Best wishes, Andre

Hello everyone! I want to create a large queue of jobs, but I don't know how to do it. Currently, when I submit a job to the card reader, it completes instantly in 0 seconds. This is frustrating because I want to observe the job's progress. I would like to learn how DOS/VS uses FG's to manage numerous jobs in different languages. Once again, I want to wait for each job to complete. My plan is to pause all execution somehow, then create a substantial queue of jobs, and finally resume execution while monitoring the ongoing processes. Could someone help me with this endeavor? Even if you can provide only one JCL file, I would greatly appreciate your help. Or if you can explain how I can create a job queue or monitor its progress, that would be very helpful. Best wishes, Andre

Hello Everyone, My name is Andre, and i am new ibmuser. All my life i thought that Altair 8800 was the "first" computer, but then i have learned about mainframes. :) My interest grew stronger and stronger, and then i found moshix channel at YouTube. That was the beginning of my journey. Well, while other people try to run most recent operating systems, i was really interested in ancient ones.Tried UNIXv7, Multics and even CTSS. But for me they are not so complicated as IBM OS/360. It is like OS from other dimension, from planet Nibiru. Some companies do not release any good documentation, but IBM is not one of them, they release TOO MUCH, and their documentation is really hard to read or understand. Maybe it was done intentionally, so people would be forced to buy support, i don't know. So why DOS/VS? For me it is because this OS is closest to DOS360, and run perfectly on Hercules. What is my goal? To write my own assembler program(not just hello world, but something more advanced) and run it successfully on DOS/VS. Plus points if it also would run on DOS/360. What is my problem? Every time i find a good book about assembler, it seems that i found a book for wrong type of assembler. Nothing works. I am truly fascinated by programmers of that period. Recently i started to read magnificent book by Bill Qualls "Mainframe Assembler Programming". He gives a lot of code examples and recommends to run them on PC/370 by Don Higgins. https://www.billqualls.com/assembler/ But it turns out, that those examples are useless, because they use macros of PC/370 program and those macros not present in IBM OS's. How to import them, i don't know. Also, i have big problem with JCL. It seems that for every type of OS there is different syntax for JCL. And lots of sites cover JCL for latest z/OS, not for DOS/VS. I am looking for help here, only because i feel that i am stuck. Maybe there is someone, who also read Bill Qualls book and was able to run his examples on Hercules. Or maybe someone would recommend other good assembly book, with examples that would work on DOS/VS. Or maybe someone would share with me universal JCL for DOS/VS that should run almost any intermediate assembly program. Any help are welcomed. Best wishes, Andre
