I am trying to use dynamic allocation information retrieval to obtain the DSORG for the data set allocated to a DD name. I've run into a couple of unexpected issues.
  1. DD not allocated. DYNALLOC returns w/ RC = 0 and no other indication of a problem.
  2. Data set specified by the DD statement does not exist on the volume. As with the first bullet, DYNALLOC returns w/ RC = 0 and no other indication of a problem.
I actually encountered the second bullet first, and only encountered the first bullet when I forced a bad DD name. In both cases, I wanted to verify my DAIRFAIL code was working.

In the real world, the app won't encounter the first error as it has already verified the DD exists and defines a DASD volume, but the app could get the second error.

Anyone have any thoughts?

I goofed. When the DD is not allocated, DYNALLOC ends w/ RC = 4. The DAIRFAIL message is pretty bad -
