Sorry abut using the word antiquated if it is perceived to be pejorative. I meant to point that both z/OS and Unix are pretty old (yet both are still useful and going strong:) Both have some nifty and some not so nifty ideas. To me, at the real world workplace, whenever I have to create environment variables that store very long directory hierarchy because I do not want to memorize that g-----e, I wish again that the good ideas from the parallel world would make it to my current world.
