Why do you expect a warning? There's nothing wrong with the code. The first
piece is assembled for a fixed start address of $400, the second one for a
fixed start address of $412. There's nothing that tells the assembler that the
first piece of code should not exceed 18 bytes. It would be completely legal
to have 20 pieces of code all located at $400 (think about overlays for
example), so the assembler cannot know.

As far as the linker is concerned, there are no "blocks" in your code, so you
cannot expect the space between the non existing blocks to be filled with
something.

I would suggest reading the FAQ, because this is where these things are
explained:

The IP address of your mail server doesn't have a valid reverse DNS:

    uz@trixie:~$ host 217.9.112.74
    Host 74.112.9.217.in-addr.arpa not found: 3(NXDOMAIN)
    uz@trixie:~$

Ask your admin to add a reverse DNS mapping (a PTR record in the in-addr.arpa
zone) for the mail server. This is considered to be good style. BTW: None of
the hosts in your IP range has a valid reverse DNS. There may be a problem
with your admin.

I'm sorry about the inconvenience, but without such filtering, I would get
more than 400 Spam mails daily!

        Uz
