Re: Obtaining the Entry Point and Offset for an abending program in the SD WA

I don't see a field called "Offset" in the SDWA so I suspect that needs to be calculated, but with out an Entry Point Address (EPA) I cant' calculate it. . Can some shed some light on my lack of understanding of this ? . We don't use SDWAEPA 'cause it is zero sometimes (don't know why). We check to be sure bit SDWARPIV is OFF in the SDWAERRD byte, and if it is, we use the rightmost four bytes of the SDWACTL1 field as the address of the next instruction @ time of ABEND. Using that information you can see if the failure was in your ESTAE exit itself or not. If not, then you can use a combination of the address of the next instruction and breadcrumbs passed to your ESTAE exit via SDWAPARM to determine which CSECT was executing at the time of the ABEND. SDWACMPC helps you decide if the ABEND is worth retrying or not.

Re: Diagram of MVS Control Blocks

One of the first handouts our class was given was a spaghetti diagram of MVS control blocks. Unfortunately, I threw mine away in 2016, when I thought my system programming days were over. I took that same two-week class in Chicago in 1980. The diagram in question (as I remember it) was a joke, right? It was impossibly complicated with curved lines and arrows and flowchart symbols all over it. It was made to generate a chuckle, not teach actual logic flow. I too had a copy once, but it's long gone. Mike -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
