OK, so I found information on the net that says SQL Maint uses the standard DBCC REINDEX statement. So, I lookup DBCC REINDEX in BOL (which it DOES list) but it has information instead on DBCC DBREINDEX.
At this point, I'll assume that SQL Maint runs DBCC DBREINDEX and that BOL has an entry for "REINDEX" to preemptively catch misspellings.
If anyone knows something different, please let me know. RH
