That information is available in Books Online ("Transact-SQL Help" under Help button in Query Analyzer). Lookup "Execution Plan pane" in the index...

"RBAR is pronounced "ree-bar" and is a "Modenism" for "Row-By-Agonizing-Row".

First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column."
