I think Intercomm is bundled in the TK5 distribution of MVS 3.8 now. They got clearance from the owners a while back as I recall. I'm assuming it's the same Intercomm you're talkin…

The s390x Linux install under z/VM boots from a virtual card reader, from cards generated by a virtual card punch from the installation files.

Me too. Status page predictably claiming 'All systems operational'!

A good summary from the UK IT trade publication that broke the story: https://www.computerweekly.com/feature/Post-Office-Horizon-s... Not sure if this requires sign-in/subscription…

Wow, Kilostream. There's a name I never thought I'd hear again :-)

There's a bunch of documentation for MVS 3.8J (or OS/VS2) on Bitsavers. IBM provide free 1-year Z access via the Zxplore program.

Haven't used it for a couple of years, but I think it's still a free login ID with 1-year validity. You can re-apply every year.

Are we to assume you want it to run on actual hardware? I imagine there are a number of OSes that qualify if emulation is acceptable. One I like: http://www.vm370.org/ Full S/370 a…

Seems to be replicating mainframe JCL and in-stream data sets. Processing instructions and input are combined in a single file. Used all the time for compiling, running utilities e…

Yes and Yes. Though there are options to get to the Unix shell via tn3270 too.

This is a reasonable introduction. https://www.ibm.com/z/resources/zxplore There's also a bunch of (sign-in required) free training at learn.ibm.com. And I think there's something …

I've seen it done fairly often in mainframe assembler - embed an 'eyecatcher' string near the top of your program and jump to the real entry point. Used as an aid for debugging whe…

Agreed. I've only limited experience with i, but more with z. After using them, the other OSes you might use start to look and feel pretty similar to each other.

z/PDT and zD&T will run current z/OS under emulation on Linux. The ADCD for use with those products includes almost all the IBM software you'd come across in a mainframe environmen…

zxplore is a free z/OS course (what used to be called 'Master the Mainframe'): https://ibmzxplore.influitive.com/users/sign_in Also a bunch of free courses here: https://learn.ibm.…

Go at least, is available for z/OS: https://www.ibm.com/products/open-enterprise-sdk-go-zos

One possible reason why: customers might want to be able to upgrade their hardware/OS/whatever and retain their 5 9s.

Try this for a bunch of free z courses (with real machine access for labs) https://www.ibm.com/training/ I've done 4 or 5 including z/OS and COBOL. There's also: https://www.ibm.co…

Makes me think of: https://web.archive.org/web/20010406062920/http://crank.com/... Issue #2 and a follow-up in Issue #4.

It mentions using 'cc' here: https://www.ibm.com/support/knowledgecenter/ssw_aix_72/print... An example using ksh: https://www.ibm.com/support/knowledgecenter/ssw_aix_72/files...

The AIX print spooler can be used as a generic queueing system - I remember setting up queues with shells as backends. Jobs sent to those queues would then be executed in sequence,…

Sorry, both the title link and the one I added seem to produce the same permission error now. I've asked the author about it and will update if I hear anything back.

You're absolutely right, sorry. I don't suppose you know how I can edit the URL? Editing the submission only seems to let me change the title. (it's my first attempt at a submissio…

A list of free resources for IBM mainframes. Includes software and user accounts. Some appear to require exising mainframe access.
