one line of results

I am trying to do a select statement where the results show up in one line like a,b,c,d,e...

I think I'm on the right track with the following code, but I have no idea what direction to go in. (I think my notes are not totally correct, but heck they're my notes. :-))

@.UM is getting wiped out after each into @.UM, how do I make it add to @.UM

declare @.UM varchar(3000) --declares variable
DECLARE abc CURSOR FOR --declares object for recordset
SELECT CONDCD FROM IBACOSTOCK GROUP BY CONDCD ORDER BY CONDCD
OPEN abc --stores results in recordset variable
FETCH NEXT FROM abc --grabs one line from recordset
INTO @.UM --stores line into variable
SELECT CONDCD FROM IBACOSTOCK GROUP BY CONDCD ORDER BY CONDCD
WHILE (@.@.FETCH_STATUS = 0) --as long as there are records in the recordset
begin
FETCH NEXT FROM abc --grabs next line from recordset
INTO @.UM --stores new line into variable
end
SELECT @.um
CLOSE abc --go back to while statement
DEALLOCATE abc --erase recordset
GOHow about...

DECLARE @.UM

SET @.UM = ''

SELECT @.UM = @.UM + CONDCD
FROM IBACOSTOCK
GROUP BY CONDCD ORDER BY CONDCD|||Yeah. I'm slow. I looked at my code afterwards and summed it up, and that's what I got. Thanks!
