Xie Bo, here is the response from the USS Shell expert. I suggest any further questions about Unix on z/OS be directed toward the MVS-OE forum. I'm surprised this showed up on IBM-MAIN, since we have not implemented, nor announced any committed plans for UNIX03. You can certainly direct them to the mvs-oe mailing list. It's still very active. The other place you can suggest they look is in the Solaris OE10 or AIX 5.3 (I think these are the right releases) doc. IIRC, the Solaris doc has a nice table of differences.
