I'm doing some work and needed to do an ATTACHX with an ECB.
So for test purposes I'm attaching IDCAMS. It runs and gives CC=0.
Ok, in the main task, I've done the ATTACHX with the ECB and then
went and did a few instructions and then did a WAIT for the ECB.
CPU trace shows I don't get dispatch again until the POST is
effected for the ECB.
I've looked at the ECB and my understanding of the doc for
ATTACHX is that it gets posted with the CC from the sub task, or
ABEND if it is that the program ABENDed.
My ECB has, what appears to be, an RB address.
Now I did have it giving me back the zero (hey, ATTACH IEFBR14,
it works).
But now with IDCAMS or an internal program (written to give S0C3
to test what happens), I'm getting other than what is documented.
I've taken various dumps, I've been tracing using SVC 50
(originally documented as NOP now reserved, but it still works as
NOP).
I tried capturing the contents of the ECB before issuing the
DETACH in the case it gets changed by the effect of the DETACH,
but it is the same before and after.
I'm just baffled.
Anyone know of a working example I could take a look at?
Regards,
Steve Thompson
