I took courses in uni for COBOL and you’re right, the language itself isn’t difficult, it’s honestly a lot like writing plain Englisch but making sure your JCL was correct, checking I think it was the spool in order to make sure your jobs were working correctly, reading memory dumps, it was a ride. I love mainframe but it feels like all jobs mainframe ask for 5+ years experience

I didn’t know about registers, thank you for this!

If it makes you feel even better, I’m a software engineer and I had lots of trouble learning to use GitHub and git, it’s embarrassing to admit it but I’m super glad I learned!

I’ve been jumping between Jerboa, liftoff and now sync. Sync just has a smoothness that the other two apps don’t have, at least in my experience on my pixel 6 pro, scrolling and everything is butter smooth on sync, the others have some odd stutters sometimes
