No there is not. And oh by the way even after you get all that you need from the Principles of Operation, be aware that there are sections of a linkage stack within which the entries are, and you cannot necessarily navigate from one section to the next using architected-by-hardware structures.

Is there an IBM supplied DSECT that maps the linkage stack entry?

Binyamin, I think there is not any DSECT to map these entries, but you can access some fields through the instructions EREG and ESTA. http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/IEA2A520/2.4? SHELF=EZ2ZO110DT=20020107113902 Regards, Philippe Leite z/OS Systems Programmer BBVA

Or must I roll my own? You may want to check the IPCS libraries. Given that IPCS does a cbf x str(lse) just fine and recognizes header, trailer and actual entry, there may be some sort of mapping/model somewhere (but I didn't check). Best regards, Barbara Nitz -- Highspeed-Freiheit. Bei GMX
