> I wonder where CA-1 picks up the extra data from. Further to my earlier answer about the DCBE .... It is possible that CA-1 picks the value up from the Tape Exits Parameters, Main parameter list. The TEPM, mapped by IFGTEP, created by O/C/EOV and passed to tape installation exits. If CA-1 does not use the installation exits interface it will have to crawl through the DCB to DCBE for cases where the LBI is used.
