MVS TK4- is very old compared to z/OS. It's like comparing Berkeley Unix to Linux. Yeah, the system calls are similar but there is so much missing. Not to mention, to understand mainframes, you really need access to the whole SW ecosystem, which includes stuff like DB2, CICS, MQ, IMS.. these are building blocks for applications.
- nix23 4y agoTrue, but you can install KICKS instead of CICS ;) But you are right, if you want that, got to zexplore. If you want a taste of Mainframes then MVS and VM/370 are a excellent starting point. BTW: If you understand "Berkeley Unix...whatever that is" then Linux is a piece of cake...not that ~much has changed.
- naikrovek 4y agoi'm sure you're right, but it's much closer than where I am today. I would like access to a proper z/OS machine so I can write some Go, but right now I'll take what I can get. And thank you for this information, I didn't know this. I don't know anything about this stuff.
