They don't use ASCII, they use EBCDIC, which has its elegant parts and its horrors (English letters are not contiguous in code-space).

The screen isn't treated as an infinite-scroll dot matrix printer, it's treated as a... as a very old visual text editor, with stencil masks, I guess.

The UI is very unified by alien conventions.

Files are not files, they are record stores.

There's a weird batch language that you use for everything.

If you're not writing a batch program, you'll be writing on top of CICS, which is a framework for, uh, realtime message processing programs and GUIs.

The DBs have their own idiosyncrasies. Etc' etc.

I’ve heard of some of the other stuff before, but I’d be very interested in hearing more about how this works!
