MS SQL 2000 Replace NULL is results

I have a view in MS SQL 2000 which is working and showing results.  There is one issue though, if there is no value for dbo.tblLeavers.fldHeadCount it shows as NULL in the results.  Can I replace this with a 0 in the SELECT statment.

SELECT     TOP 100 PERCENT dbo.tblHeadCount.fldCostCentre, dbo.tblHeadCount.fldDate, dbo.tblHeadCount.fldHeadCount,
                      dbo.tblLeavers.fldHeadCount AS fldLeavers
FROM         dbo.tblHeadCount LEFT OUTER JOIN
                      dbo.tblLeavers ON dbo.tblHeadCount.fldCostCentre = dbo.tblLeavers.fldCostCentre AND dbo.tblHeadCount.fldDate = dbo.tblLeavers.fldDate
WHERE     (LEN(dbo.tblHeadCount.fldCostCentre) > 1)
ORDER BY dbo.tblHeadCount.fldDate DESC

yes, using ISNULL()
SELECT     TOP 100 PERCENT dbo.tblHeadCount.fldCostCentre, dbo.tblHeadCount.fldDate, dbo.tblHeadCount.fldHeadCount, 
                      ISNULL(dbo.tblLeavers.fldHeadCount,0) AS fldLeavers
FROM         dbo.tblHeadCount LEFT OUTER JOIN
                      dbo.tblLeavers ON dbo.tblHeadCount.fldCostCentre = dbo.tblLeavers.fldCostCentre AND dbo.tblHeadCount.fldDate = dbo.tblLeavers.fldDate
WHERE     (LEN(dbo.tblHeadCount.fldCostCentre) > 1)
ORDER BY dbo.tblHeadCount.fldDate DESC

side note: try to use table alias names:
SELECT     TOP 100 PERCENT hc.fldCostCentre, hc.fldDate, hc.fldHeadCount, isnull(l.fldHeadCount,0) AS fldLeavers
FROM         dbo.tblHeadCount hc 
LEFT OUTER JOIN dbo.tblLeavers l
  ON hc.fldCostCentre = l.fldCostCentre 
 AND hc.fldDate = l.fldDate
WHERE     (LEN(hc.fldCostCentre) > 1)
ORDER BY hc.fldDate DESC
