Hi Andres:

As you've discovered, the ToE ads have been removed in HTCondor 24.
There is, an easier way to get the exit status (including whether it
exited because of a signal) in the dag post script: When you declare the
post script for the node, if the command line arguments to the post
script include the string $RETURN, dagman expands that to the return
value of the job, e.g.

SCRIPT POST A post.sh job_status $RETURN

when the dag node "A" completes, the script named "post.sh" will run
with the arguments of job_status 0, if the job exited 0, or job status
-9, if it was killed by signal 9.

Let us know if this solves the problem, it should be easier than parsing
a classad file.

We do have the European HTCondor workshop coming up this fall in Prague
-- I do know that researchers from EUMETSTAT have attended in the past,
perhaps you'd be able to attend this year, and we can talk more in person?
