    There's too much speculation and little details with no further replies from the OP.

    I don't know about that, ol' friend.  If you stick only with the basics mentioned in the original post, there's no speculation required.

    I DO agree that the OP appears to have abandoned this post, though.

    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.

    Change is inevitable... Change for the better is not.
