Use of the @-symbol in zone files.

Hi,
I've been doing some experiments with a zone file and wanted to check if
what I've done is O.K.
The scenario is as follows:
Up to now, when I've wanted to make both www.domain.dom and domain.dom,
point to the same place, I've made two entries in my zone files that
look like this:
www IN A 111.111.111.111 (IP number just an example IP)
IN A 111.111.111.111
This has always worked fine, so I have no problems with this in
principal.
However, we're working on a DNS admin system and I'm a bit concerned
that the 'blank' record may cause some problems.
For that reason I've replaced the 'blank' record with an @, as in the
example below:
www IN A 111.111.111.111 (IP number just an example IP)
@ IN A 111.111.111.111
As far as my testing shows, this does what I want it to do, but I just
wanted to check if this is O.K., or if it may cause problems.
Does anybody know of any reason not to use the @-symbol in this way?
Regards,
