Thanks Mark, Unfortunately, I'm not familiar with the term OCO.
Using a portion of your IPLINFO exec as an example: CVTIXAVL = C2d(Storage(D2x(CVT+124),4)) /* point to IOCM */ IOCIOVTP = C2d(Storage(D2x(CVTIXAVL+208),4)) /* pt to IOS Vect Tbl */ CDA = C2d(Storage(D2x(IOCIOVTP+24),4)) /* point to CDA */ IODF = Storage(D2X(CDA+32),44) /* point to IODF name */ How/where did you find that CDA was at offset +24 of IOCIOVTP? And subsequently, that the IODF DSN was at offset +32 of CDA? Surely I'm missing some address maps? Specific to the latest dead-end I'm encountering, one of the SMS guys I work with asked if there were a way to list esoterics *without* having access to HCD, or relying on a vendor product that could produce such a list. I was thinking with a bit of investigation, I could find it somewhere in storage using Rexx code similar to above. Like I mentioned, IOVT/IOCIOVTP isn't the first address I've encountered that once I got there, I didn't know exactly what I was looking at! I do think the Data Area manuals are extremely helpful by noting the size and the different information contained, but I seem to hit a dead end. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
