You want to send stdout from ssh remote session directly to #zos dataset? Forget, redirection in #USS (Unix System Services) doesn’t work this way 😡 So you must write code … 😀
Hmm 20 lines C program resolved my problem, really? Oh IBM😱😂
The same in reversed direction - from dataset to stdin for ssh session. Code looks mostly like previous variant replacing write by fread.

Mind blown. You can run IBM #zos on a PC with a personal edition license.

And it has IBM #COBOL inside it. I don't understand why this was so hard for me to find. Looks like I need a new machine (linux host, 1tb drive space and then enough oomph to run a VM)

@Sheep_Overboard I am going to have to object. I work for mainframes, and our host code is 98% COBOL, it's very fast and reliable. A lot faster than Java, C, C++ etc. According to a 2022 study there are 800 billion lines of COBOL in use on a regular basis. I admit, I write z/OS assembler, and am a bit biased, but COBOL is still incredibly popular.

"According to surveys by Micro Focus (2022), around 800 billion lines of COBOL code are used in production every day."

To any #mainframe #zos peeps out there… do you have any PARMLIB monitoring at your shop?

I’m bothered by this one statement from Long Pela’s February 2023 Quarterly:

#IBM haven't produced a single utility to validate z/OS PARMLIB settings.

My possibly ill-informed opinion on the mainframe developer market

#zOS work has so many barriers
- Can't run it locally. Only 1 training program at IBM for terminal access. (wrong! prersonal edition exists)
- The only mainframe code you can run locally is MVS from the early 1980s
- GNUCobol is probably not like modern IBM Cobol
- Microfocus appears to be in financial crisis and you can't even get a trial license compiler, let alone a personal license compiler

@carlwgeorge @vermaden @samurro @tara Well, that confirms you went #ReplyGuy on me in the most disingenious way possible, wasting everyones' time and patience in the process.

• Gues what: Good luck with that sales.pitch, cuz I'd rather give @ubuntu or @opensuse my money cuz that nonchalant attitude is insulting.

If you (or #RedHat / #IBM) don't want to support #OpenSource or anyone using anything they made for #RHEL without paying, then shure you can do that but then don't expect people to like you.

• #grsec already did that and I'm shure it resulted in 0 extra customers.

#CentOS was in fact a "gateway distro" and had Red Hat not axed it I would've convinced my (fmr.) boss to consider paying for an RHCSA, but alas I've invested time and effort migrating from CentOS to #UbuntuLTS and even negotiated commercial support from #Canonical instead, because they were more friendly and welcoming.

• Personally, I think that Red Hat should just be honest and just stop any #Linux contributions, instead try to upsell their customers to #zOS on z/Architecture #Mainframe|s instead cuz that was such a great business...

Even "Source Available" like #Tarsnap is better - espechally in #finance - because having actual #SourceCode available is a matter of #trust.

• And #transparency is the reason people choose #Linux over #Solaris and other #Unix-esque OSes.

But I'm not getting paid to prevent Red Hat from continuing to shoot itself in the foot...

• In fact, I'd love to short it into the ground!

@timb_machine paging @mainframed767 to the #zOS desk.

What's the easiest way to get a z/OS USS shell to play with?

Can you connect output from your COBOL copybooks to @ApacheKafka?

You can now 🤯

"IBM® Open Enterprise SDK for Apache Kafka® is a no-charge SDK that allows COBOL or C/C++ code running on z/OS® to natively communicate with a Kafka broker and to transform between COBOL copybooks and JSON events." #ApacheKafka

See, I told you lots of familiar distributed tech is landing in the #mainframe world!

And that's a wrap.

After 40+ years working in the mainframe arena I just signed off for the last time. I have now entered the retirement phase of my life.

Can't wait to see what happens next!

IBM CONTROL PROGRAM OF OPERATING SYSTEM/360 (Full)

Full film IBM B&W film introducing OS/360. The title is IBM CONTROL PROGRAM OF OPERATING SYSTEM/360. IBM's System/360 mainframe turns 50 (60 in 2024) soon and since YouTube now allows much larger uploads here is the complete introduction to OS/360. Preserved thanks to Michael Stack:

As a muscle memory check from things 33 years ago, I wanted to know how much the #ibm #mainframe under #zOS has changed from /370 back then.

Yes, we are now at #JES3 - and the new things for me were PDSEs and USS - feels weird calling #OMVS and having a #Linux environment #shell on the mainframe. Ah yes, we did not have #FICON either back then to define CHPIDs but the 3380 and 3390 were actually huge boxes connected via #bus and #tag cables.
