Indeed. A very, very long time ago, back at UofW, we had a machine called PRIV, that had a table of users and commands. You could "SMSG PRIV somecmd" and if you were enabled, it would do it. It was very granular, down to the specific operands: This let us do things like let a professor force his students, without giving him general FORCE privs (I was going to write "force his admin", but that had the wrong connotation!). Anyway, I was doing some maintenance to PRIV. I logged on and was in a CP READ. Since I didn't want to take it down mid-command, I had the brilliant idea of doing an "SMSG * SHUTDOWN" (it was single-threaded, of course). And then I waited. And waited. All of a sudden one of the operators comes running out of the Red Room (the raised floor), yelling "SYSA just shut itself down!" Of course, I immediately realized what I'd done. Hey, they were only students ;-) ...phsiii
