MVS has a filesystem that is integrated into the base operating system; it seems pretty strong to me. It is CP has *no* integrated filesystem. I find nothing inherently evil about a kernel reading user-space files. Granted, I was reared by my parents (or wolves; historians aren't sure on that point) to believe that it is ok. Apparently others were brought up to believe otherwise. I can respect that. "Because that's the way it's always been done" doesn't *have* to be the rule we live by, eh? :-) Alan Altmark Sr. Software Engineer IBM z/VM Development ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
