Hmm, the same happens for me. Perhaps $HOSTNAME is null until polled, so
it is generated upon request by the command line call?
One possible workaround is to set an env variable right before launching
NETNAME="$HOSTNAME" chuck myfile.ck
and access Std.getenv("NETNAME") in your code.
I wasn't aware of setenv or getenv before. Did getenv("HOSTNAME") work
in the past?
