- use REXX and CLIST as batch scripting languages, giving the mainframe user access to any feature hosted on the box (batch processes, LU6.2 and TCP/IP communications, etc.)
- support transnational networks with a single point of control.
- support 200 to 300 simultaneous users with 10 to 15 large scale batch processes all running concurrently.
- support tetra-byte size databases with response times measured in single seconds.
- etc., etc., etc.,
PC's never took over. PC's added to the mix and skill set that professionals learn and understand.
No, VSE/ESA, which is a direct descendent of DOS/VSA, is still sold and supported by IBM.
Also, the OS/390 does *not* have a Unix Kernel, but it can support a POSIX compliant program program (TCP/IP, Hierarchical directories, etc.) under OS/390. Yes, you can do Unix development on a mainframe, under a mainframe operating system, and recompile that application under Unix.
Actually, many people advocate mainframes as web servers. Check out Schwab's web site. It is served off of a *cluster* of mainframes. Schwab and IBM teamed up to create the networking required to do this. Why, because when Schawb lowered their prices for individuals, they got swamped. In response, they bought a bunch of mainframes, created redundant data centers, and now server their customers.

Yup, mainfames still use JCL. They also,

Okay, so I *do* like the virtual stuff and the 3d fluff. That's why I use olvwm.
Yes, my brother. MVS still is the sweetest.

Thanks. Glad to see I'm not alone.
