In my case, that would not be an error, my needs are for a rather
custom checking system.

Very nice, thank you for that. This is a good start for me to see
what many of the possible return codes are that I need. My tool never
gets used in production, this is just something developers are going
to use. I installed for them DLZ, and get a lot of "DNS is down"
emails from the developers. In all reality, "database has bad data"
is more accurate. I just need a tool to show them what is going on,
without them having to learn all the replies dig may send back.
Thank you again for your link, most helpful.
