Funny, I can use 70% of Unix commands on the mainframe I work on. We are running IBM's webserver on the Unix System Services (USS) part of OS/390 - believe that its just Apache with a few add-ons. The network team are logging in and using the netstat command. Some Oracle people are developing stuff for 9i - they complain about the tight security. USS security is not all done within the USS segment but by the OS/390 security software. I also didn't think that USS was added to OS/390 until quite recently. 

I'm happy - it's where I'm trying my newbie perl programming skills (see other thread).
