Re: Curious about ATTACH and 'SVCR 0'

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

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! :-)

Curious about ATTACH and 'SVCR 0'

2009-09-15 Thread Steve Austin
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 -
