There is another difference between running under an ESTAEX and an IEAARR, and
that is you cannot use IEALSQRY to determine the linkage stack depth if you
need it for retry. You must keep track of it yourself.

There can be many. There really is no way to know precisely at a given instance
because you could scan the TCBs in an address space and check their dispatch
flags, but that could change from under you at any instant.

If these memory objects were obtained by you, you could place the A(Owning TCB)
in the USERTKN when they are obtained.
Then, you can use the REQUEST=LIST to filter on that USERTKN and thus obtain
the information you want.

Sometimes R15 contains the entry point.
If the routine receives control from ATTACHX or LINKX, for instance, and if it
is to run in AMODE(64), then it does not.
A better solution is to use
LARL R12,PROGNAME
USING PROGNAME, R12
which has no dependency on R15.

Programs executing in AMODE(31) can and often do store critical data in the

The best way is to run under z/VM. Set all processors off line except for one,
and you can step through the code. I'm never used z/XDC to debug an SVC. It
would be interesting to hear what Dave Cole has to say.

Ron,
There isn't, because while the SRB is running, there is no control block which
contains its status.
Here's a suggestion: obtain ColeSoft's XDC debugger product: it fully supports
debugging in SRB mode. Full disclosure: I have no connection with this vendor.

Ron,
Now I understand. Here are my suggestions:
Add SRBTIMER to each SRB to prevent uncontrolled loops to begin with. Your
recovery routine can then capture registers and other critical information.
Add PTRACE entries at critical code points, like maybe at start of SRB logic so
you can locate
Issue FEOV when you want to go to the next volume.

The DCB is a control block in memory. There is no DCB in your file.
What I think you are looking for is information in the VTOC entry called DSCBs.

There already is a simple way of handling this: Issue a PR with a return
code in R15 which is passed to the caller.
Each time you invoke a routine using BAKR, when it returns, check the
return code, and if it's non-zero or some special value jump to your
next PR.
