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.
Or must I roll my own?
I want to access data in a linkage stack entry a few back (supervisor state
routine).

Should you use the mailblocks package and expect a response from me,
Binyamin,
I think there is not any DSECT to map these entries, but you can access
some fields through the instructions EREG and ESTA.

Sadly here is no way to use those instructions to get to other than the last
state entry.

The POPs has it.
A c-code mapping isn't much help.

There is no IBM-supplied DSECT for the linkage stack, but the stack
format is described in detail in PoPs. While a unit of work is
dispatched, CR15 has the virtual address of the last

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).
