Oh cool, didn't think of IPCS. Of course. Duh. Anyway, whoohoo, I found what I was looking for (sort of) the thing which started me on this thread. It's hung off of the TIOT which I looked at up and down for ages. But it's not an address. It's a 3 byte field called an SWA and points to the JFCB. You see, I wanted to know where the datasets allocated to the DD's in my TSO/ISPF session were located.
I know that often people write Rexx or CLIST's that Outtrap LISTA ST and parse that to reallocate SYSPROC. I wondered if I could get it from the TIOT or similar control block. And it appears now, with a little diligence and some good advice, that I've found a way to do it. The answer for me in this case was the advice to simply go through the SHOWZOS source. Sure enough there it was staring me right in the face (at around line 20,800). I just need that exec from Gilbert to decode the SWA and voilá. I could have asked outright, but I'll never learn that way, and besides there's really nothing much better to do here in Helsinki on a weekend. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Edward Jaffe Sent: 6. tammikuuta 2008 21:24 To: [email protected] Subject: Re: z/OS and VM Control Blocks Lindy Mayfield wrote: > I like to use ISRDDN to make sure I'm getting the right information and > offsets before I try to code anything.

But, it's primarily intended for "lowly" programmers without IPCS access. In the absence of other tools, I think most "heavy weight" developers tend toward IPCS with SOURCE(ACTIVE). All of the CBF models and most of the formatting commands and verb exits are available in that mode. -- ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
