Lindy,
You might try the following procedure:
01) Add a WTOR just prior to scheduling the SRB code. The WTOR text
should indicate the address of the SRB routine and its length. You
should be able to issue SVCs there and handle WAITs.
02) Start GTF to capture SLIP trap GTF trace records.
03) Run your program. When the WTOR is displayed on the console use the
address/length of the SRB routine in a slip trap as follows:
SL
SET,IF,EN,ID=xxxx,ACTION=TRACE,TRDATA=(STD,REGS),RANGE=(starting_address,ending_address),J=target_address_space_job_name,END
04) Respond to the WTOR so your code will continue to execute (i.e. -
schedule the SRB).
05) You should see a "slip trap matched" message when your trap hits.
06) Delete the slip trap and stop GTF.
07) Run the GTR trace output through IPCS.
This will give you an instruction by instruction trace. There is a good
bit of data that is displayed by this trace. You should be able to
verify that your program is executing as you expect.
Notes:
01) Replace the WTOR with PUTGET if your target address space is a TSO
session as the WTOR will not work quite like you would like.......

ABEND is allowed but it didn't do anything. It didn't put anything in
LOGR.
But I did a LA R6,X'666' and then a DC X'0000' and in the LOGR I could
see my register set. So perhaps it works.
I mean, so it appears to work! Whoo Hoo! Thanks to everyone's help and
patience with my questions. Only took me 6 months to get this far. (-:

So running "to completion" is like "working as coded." All code ever
written works as coded.
One way to know if it works, after you fix all the problems you discover
with LOGREC et al., is to put a WTO at the very end. Of course, you
have to
code the WTO so that it does not use an SVC (LINKAGE not = SVC; some
macros
allow LINKAGE=SYSTEM, others allow LINKAGE=BRANCH; check the WTO doc).
And
remember that the WTO system service will alter some registers. Check
the WTO doc
to see which ones.
