I'm running a residency in the Autumn on 2.1 code (and you'll see an announcement as this one is expected to welcome customer etc nominations shortly). I mention this because Symbol Substitution via PARMDD is quite likely to feature. What I'll want to figure out then is whether the "only in instream" restriction is going to be significant.
We're likely to parameterise things that look like clone jobstream number as well as some character strings related thereto. But for now thanks Peter for pointing out this restriction. It might affect what we do.

(was: PARMDD?) Sent by: IBM Mainframe Discussion List <IBM-MAIN@listserv.ua.edu> >Think "Black Team". Sorry, but that is not relevant. We try not to waste time and resources implementing things that no one needs (with less than 100% success, I'm sure). It is not a question of exercising the outlying cases of an implementation trying to break something. >Should I infer from this that only symbol substitution by instream data >set processing occurs, and if the PARMDD data set is not instream >no symbol processing is possible? Yes you should. There is no intrinsic support in "GET" to ask for and/or get symbol substitution; it is only in JES instream data set processing (not a great state of affairs, in my opinion) >[S]hortly before the jobstep program >attach" sounds far too late for JES JCL symbol substitution. Perhaps I am missing something. Why would it be "too late"? It is before the program gets control. It is after the JCL symbol values are known.
