The lack of quotations were a typo.

What I am trying to accomplish is that all my virtual domains map back 
to my actual
domain of www.qcislands.net, and I want to be able to change "one file" 
for all the various
domains' IP numbers.

So not only did I try the above, I also tried:
lifeboatscanada.com.   IN A   $INCLUDE ip_fyl_name
... which failed because I presume the $INCLUDE must be at the beginning 
of a line
... the re-load complained that $INCLUDE was an invalid numeric value

so I tried
lifeboatscanada.com.   IN A
$INCLUDE ip_fyl_name
... which failed for a reason (I think) "line not terminated" (or 
something like that)

is there any way to have the 100 or so virtual domains which I have, 
fetch their IP
from one common file, so that if my server changes IPs, I can change 
only the one file
rather than all 100 of my virtual setup's ?

Thanks!
