The entry we are talking about is written when an SVRB terminates (and also
for end of processing for such things as type 1 SVCs) Any record
associated with a terminating PRB has nothing to do with this.
When you're running your program and look at the RB structure, you'll see
that the oldest RB

I am curious, too, how this is addressed in 1.10. (We're not there yet).
Here is what I learned *why* this behaviour exists (narrowly looking at only
tcbs):
When the dispatcher dispatches any tcb, all it does for the system trace entry
is take the WLIC's last two byte (from the RB pointed to

This is occuring on z/OS 1.10. Is there specific maintenance required?
What type of entry will I see when the anomaly is addressed?

You remembered the instruction wrong. 0A0D is the SVC for ABEND, not
EXIT, which is 0A03. ABEND would be the only way to end a task normally
in the Hosed System Architecture which I discussed at SHARE and CMG
sessions in the early 1990s. :-)
Wow, someone's actually *reading* my ramblings! :-)

I believe that this anomaly has been addressed in z/OS 1.10.

Hello,
I have noticed in a number of traces, that for a newly attached TCB
there is a 'SVCR0' without a previous 'SVC 0'.
Is this really a return from an EXCP SVC or something else masquerading
as such?
Thanks
Steve
