1. XEDIT is a big difference -- having a full screen editor is great

2. REXX nucleus extensions -- I dont THINK VM/370 could load extensions for REXX

3. Fullscreen utilities, e.g. FLIST.? I don't think fullscreen CMS *ever* caught on though.

4. Shared File System.? Hard to say how useful this is for a single-user system.? Probably not very.

I'm sure there are some other big changes that I'm glossing over.? The big enabling change was the DIAG X'58' support for fullscreen commands in CP, which I think happened in VM/SP not VM/370, and that change happened in the early 80s, I think.

Modern CMS has more utilities to interoperate in an internet environment, but I'd be hard pressed to say "why CMS" if you tried to figure out today what OS you wanted to use.? I think the most compelling case for VM today is to run hundreds of Linux VMs, but even then I'm not at all convinced of the value proposition.? I certainly can't think of anything that CMS *does best* relative to what you're used to with Windows, Linux, or MacOS.
