Alter to specify a fillfactor?

For SQL2000 - I would like to be able to alter indexes on a table to specify
a fillfactor where previously a fillfactor was not defined.
I first tried this on one table in Enterprise Manager where I specified a
fillfactor of 80 for the clustered index. I ran profiler to see how it was
done. It looks like it dropped the Clustered Index and then rebuilt it.
I was hoping that there was an ALTER statement that I could run that would
effectively update the fillfactor definition so that the next time I ran
DBREINDEX it would take effect. Is this possible.
Thanks in advance!Fillfactor is not maintained during regular DML operation; it only matters
when an index is built. Therefore, there is little or no need to introduce
ALTER INDEX statement to specify a fillfactor that will not be used. When
you are ready to build/re-build index, you can specify fillfactor in DBCC
DBREINDEX/CREATE INDEX statement; after the index is built, the fillfactor
number is stored in system table for future index build to use.
