Well yes, they have to be loaded into VS to be processed. In the case of block read/writes they precede the data records in the buffer. But whatever was being discussed at the time I wrote that had to do with record read/writes, in which case the BDW and RDW would not be accessible from the buffer: so perhaps I should have said 'not accessible' instead of 'not loaded'.
And you keep digging a bigger hole. While I have written production programs in many languages, most of my career was spent on assembler, on multiple platforms. If you had bothered to look at BSAM and QSAM, you would not be making these absurd statements. While QSAM has a DATA mode, normal use of variable format always includes the RDWs. In the original context, other than references to IEBGENER, there was no mention of the program's language, so you're on shaky ground; and IEBGENER definitely uses QSAM, or BSAM, as appropriate, with full access to the control data.
If I dealt only with MVS, I would have the time to refresh my memory: but I don't; I work with subsystems. By CCW EXCPs I am simply emphasising the fact that the channel programs (CPs) are issuing CCWs (which have direct access to DASD devices).
And more of the same. EXCP is a specific reference to an MVS service, and the macro used to invoke it. EXCP uses CCWs, CCWs don't use EXCP. And channel program do not issue CCWs, they are CCWs.
True. I translate my thoughts into words and for this I use whatever suitable word - not necessarily the most appropriate one - first comes to mind.
This group is about sharing information about mainframes, and providing help to people who are stuck. That entails effective communication, which is not achieved by using well-understood concepts in inappropriate ways, or creating your own arbitrary definitions for common words. I get the impression that you misunderstood something in the original thread, made an inappropriate post, something all of us have had happen at some stage of our careers, and rather than own up to the misapprehension, you are trying to argue your way out of it. That not only wastes everyone's time, but has already made you appear incredibly foolish.
