no default TTL error

[Randy Rokosz]

The following question in the FAQ referred to a problem I was having:
------
I'm getting an error: No default TTL set using SOA minimum instead.
Since BIND 8.2, you need a $TTL directive to set the default TTL for the
zone.
Add a '$TTL XXXXXX' directive prior to the SOA record for the zone. (XXXXXX
denotes the default TTL in seconds.)
-------

I added the string '$TTL 38400' before the SOA record and it
didn't work... can someone provide a sample syntax/file for this?

Thanks!
