I want one, what's the power bill run on that thing?

Hi Moshix, is there any way to obtain the two ready made mvs with jes3 binaries any more? Both ready-made mvs3.8j links from your blog are broken. I realize that IBM sold JES3, but it looks interesting enough to play with!

Dad worked for IBM. In the late 80s he had a dial in and I used VM a lot. I also wrote a REXX script to solve a problem for him and it ran in MVS. Having used both, 15 year old me certainly preferred VM to MVS :)

I don't think the current CPUs are "PowerPC"... I think they are "Power", of which PowerPC is an adaptation/subset...

Really cool, especially being able to ge it for free. Also good to be prepared, just in case NASA ever decides to re-deploy the space shuttle fleet, Then he can be a mission control backup site for the Johnson Space Center.

Wow. I learned how to writer Pascal programs on VAX/VMS systems at my university as my computer science major. Later I switched to C/C++ programming after my graduation.

I started-out learning programming in PL/C in the mid-1970's in a mainframe environment. I really liked the mainframe environment because everything worked well and was well-documented. PL/C is a wonderful language to learn and work with. I do not mind typing. I have always placed many comments in my programs. I learned to type with ten fingers in high school.

I recently discovered your channel. I am glued to it.

I'm just begining my first steps in COBOL, I have MVS/CE and TK5 running, but due to my limited time to learn, which one is more similar to z/OS? (since I can't practice on a real mainframe and I need to be ready soon to apply to a job) I know they are both based on the same version, but JCLs are slightly different, the location of libraries,etc. Thank you!

Yes saw it. Thanks !

Just check and YES its still on Internet! the site is www.spflite.com/ I'm a happy user of the editor, but can't get language specific high lighting to work for Cobol (would be nice)

I have a running copy. It went open source a few years back when developer stopped maintenance. I'll see if I can package it up for anybody who wants it. I'm on Win 10. :-)

Love ISPF! Wish I had it on my PC again. Last version I had was SPF/PC 386. Is there a current version for purchase and where?

PL/1 was a favorite of mine, too. I haven't used it in about 50 years, however. My other favorites have been IBM assembler, APL, and now Python. With PL/1 I saw many problems caused by a mismatch in converting the contents of variables of different types. Seems like my idea of what I was asking never matched what the compiler assumed. I adapted by making it a rule for myself to always specify the conversion I wanted explicitly. Why does the cataloged procedure end in CPLG? I expected simply CLG. Thanks for posting this.

I have downloaded and extracted TK5 and installed the hercules emulator and c3270 but when I run the MVS shell script I get: hercules: symbol lookup error: hercules: undefined symbol: panel_display_r - what do I need to do next?

Hey Moshix, great series. Quick unrelated question: what song did you use in the introduction? I love it. Thanks!

Hey Moshix, when will we see a TK5 loading InterCom. I think its all there just needs to be started and programs to execute. I can not find anything of it getting loaded to MVS. Thanks again for your great videos.

That's why the Unix dd command (I used it on Linux to write disk images to bootable USBs) uses unusual syntax if=xxx of=xxx bs=1M instead of standard Unix command syntax - it's taken from the JCL :D

This was great! I found all the PDF's for these books thank for mentioning them. I am finally understanding CICS and almost to writing my own cobol program using KICKS! Great fun.

UFS on MVS 3.8, incredible !

Sorry for nitpicking but at 26:09: Browser-based games using HTML canvas typically aren't limited by the CPU speed, as they typically use requestAnimationFrame to wait until the next frame needs to be rendered. requestAnimationFrame is a rate limiter that limits the frame generation typically to 60 fps. So, having a computer that runs JS faster shouldn't result in the game running faster :D

I begin to wonder whether it would be possible to create dedicated hardware for MVS 3.8j? I realize it won't be nearly as performant as a current Z system, but it could spark inspiration and a new community of tinkerers expanding on this concept. Would do you think?

How do they find all those film references?

There’s a curious bug in the ISPF ship with Turnkey 5 update 3, corrupting sequence numbers in my COBOL program under option 3.4(e) and then also when inserting a line, the line numbers change to 3350 in red? It’s really really bizarre. Doesn’t happen in RPF.

It's very nice to see what you've done here Moshix. Looking forward to your Rexx contributions for HTTPD. --Mike

Trying to use html using tk5 but I am using localhost because TSO does not have an IP. I noticed you were using an IP. How do you assign your system with and ip address. When I use localhost:8038 it brings up a web hercules html page system log and localhost:8080 does not connect. Thanks

GENIUS! Thank you.

Amazing!

So it's possible to run Lua on TK5?

What is your Terminal emulator called? (not the 3270 emulator)

Will you be doing a MVS-TK5 install. Would like to see it. Thanks

Hello sir I am interested to learn programming in COBOL Where I can download compiler

What is the phisical block size and how many blocks can store in a track?

Hey moshix I just found your channel a couple weeks ago, and am having a blast with TK5. However, Can I Ask A Favor ? When you are showing us how to do things, sometimes you enter a 1 byte command/option and you hit ENTER so quickly it's difficult to see what you typed. Please Please if you could Pause for a moment before you hit ENTER. This would give us a chance to pause the video to see what you typed. Thank You Thank You Thank You. Can I buy you a coffee ?

Hello moshix, this sounds great, but I am worried if this installation can erase the new implementation of KICKS I recently added. Is it secure to install it over KICKS and not losing it?

I've been struggling my head trying to install KICKS until I found this video talking about the unattended mode. I used to launch "mvs" in Linux and, after that, "start_herc", but this instance of hercules was not binded to the first one under mvs and I was getting crazy.

Thank you for this video. It is the most comprehensive review I have ever seen. I was glad to see you included DOS/360 as when I told people I worked on DOS they assume I meant MS/DOS. They never heard of DOS/360. It was the right operating system for many users.

recognized the intro tune right away (satelite.s3m) downloaded it from the mod archive back in 1998 if memory serves. Either that or it came pre-bundled with a sound card I bought. don't remember which. listened to it dozens of times over the decades

Another great video, Thanks! I'm an old programmer, loved COBOL in college and at my first job running on a PR1ME Minicomputer. But lately have been interested in learning the "Mainframe" environment and this video helped a lot!! :) BTW, whatever happened to "Mini"Computers? It looks like they've become extinct except maybe for hobbyist reliving their earlier careers?

I remember working for a large company. They ran an IBM 4341. We've come a long way.

The Domain OS was mostly written in Pascal. I know the guy who ran the PASCAL users group.

Where PDF?

At my times @ EMC we 've had a feature called "SRDF" for disaster recovery. We copied disk unit data from one site to antoher in real time. Typically done via fibre or what you call it "ESCON". Failover scrips were provided by EMC in coop with the customer. Even Sysplex was covered.

In early 70s we had access to VM/370 in high school. I liked virtualization. Someone told me that someone managed to boot VM/370 inside itself 9 levels deep! Then when X86 hardware virtualization came out, I had to make it boot inside itself 10 levels and run Linux inside that (s.l.o.w.l.y) :D It was fun knitting pagetables.

Shame on you for replacing the actuel sound of a starting mainframe with the sound of a Boeing 747 !! Just kidding... I'm a mainframe engineer :D What about the electricity bill for that month ? how much million euros did you pay ?
