What level of UNIX is z/OS

2005-06-10 Thread Don Ault 
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.

No, it was OS/390 V1R2 that first got the UNIX branding. z/OS is the
successor of OS/390 and z/OS V1R2 was GA in 2001

IIRC, MVS/ESA 5.2.2 as well as OS/390 1.1 were at XPG 4. OS/390 1.2 got 
the XPG 4.2 (UNIX95) branding in 1996.

Dear Don Ault，

Thank you very very much for your wonderful reply!!!

I care about the shell and utilities difference between Unix95 and Unix03 
for zOS Unix. I've gone through Unix95 and Unix03 shell and utilities 
standard publication and my question is:* Is there any detailed documents 
about "what's new/difference" about a shell or utility (eg. sed)?* I mean 
the shell and utility description of Unix03/Unix95 standard publication is 
too long (more than 30 pages) and the change history is too short (less than 
10 lines). I just want to know the detailed difference between different 
Unix standards about a shell and utility. Any suggestions are welcome and 
appreciated!
  Thank you!
 Best Regards,
Xie Bo

What level of UNIX is z/OS

2005-06-08 Thread Don Ault 
Here is a much more precise answer to the question.  Thanks to Nick Carbone
in the C group for the response.
z/OS is sitting at the XPG 4.2 branding level achieved back in MVS 5.2.2.
You mention UNIX 95.  I suppose that could be considered equiavalent to XPG
4.2.  Since then, we have implemented some UNIX 98 (XPG Issue 5), some C99
(ISO/IEC 9899:1999), and some UNIX 03 (XPG Issue 6) functions over the
years.  We are designed for full support of C99 in R7.  We are neither UNIX
98 nor UNIX 03 compliant at this time.

The pertinent feature test macros added since XPG 4.2 are:

_XOPEN_SOURCE 500   exposes some UNIX 98 (automatically turns on the
other feature test macros to bring in XPG 4.2 interfaces)
_ISOC99_SOURCE  exposes some C99 (does not automatically turn on
any other feature test macro)
_UNIX03_SOURCE  exposes some UNIX 03 (which includes IEEE POSIX
1003.1:2001) (does not turn on any other feature test macro)

The C/C++ Run-Time Library Reference should indicate the level of standards
implemented.  If information there is unclear, incorrect, or otherwise
insufficient, this person can contact me directly and I will take care of
the issues.
