Omer,
_ should also match ^, so this is not it, or if it is, it's a bug :-)
[See the same page you referred to, _1300_ does account for
^1300(space).]
Also, be careful with ^200.*, you would match "2001 100 5 " which is not
what is asked for, and you would loose points, or permit transit,
depending on
the task at hand :-)
Regards,
