how to identify the fixpack level?

hi,
for sql server 2000, how can we find the fixpack(service pack) level installed on this sql server?
is there any command, or any gui tool to identify the level?
tnksSET NOCOUNT ON
SELECT CONVERT(CHAR(25),@.@.SERVERNAME) AS 'SQL SERVER',
SUBSTRING(@.@.VERSION,23,4) AS 'PRODUCT VERSION',
SUBSTRING(@.@.VERSION,35,3) AS 'BUILD NUMBER',
CASE SUBSTRING(@.@.VERSION,35, 3)
WHEN '194' THEN 'NO SP'
WHEN '384' THEN 'SP1'
WHEN '534' THEN 'SP2'
WHEN '760' THEN 'SP3'

ELSE 'Unknown - may be a Hot-Fix version or script out of date'
END AS 'SERVICE PACK'
set nocount off|||thanks philio,
how about service pack 3a, is there an id also to distinguish it from sp3??|||SP3 and SP3a have identical build numbers (760).

Also, you can use this:

SELECT
cast(@.@.microsoftversion / power(2, 24) as varchar(2)) + '.00.' + cast(@.@.microsoftversion & 0xffff as varchar(4)) as VERSION

To derive version info...
