If you look at my original post, I was asking if it was valid. Not stating it as a fact. So far, I've gotten a lot of tuning recommendations and a maybe. None of that has answered my question. We are attempting to size a re-development effort. And, the tuning recommendations, while valid, are not addressing the question. Nor does a maybe, or an asking where the number comes from. Can anybody answer the question: "What does it cost, in instructions (approximately) to do a VSAM I/O?" - -teD O-KAY! BLUE! JAYS! Let's PLAY!
