I don't (yet) handle multi-row queries so this was rejected:

    Query

      Vend_Reb | Rebate | Curr      | FxRate           |
               | _r     | "USD"     | CHANGETO ~FxRate |
               | _r     | NOT "USD" | CHANGETO 1       |

     Endquery

Easy. Just (for now) split the query.

But whats that _r link intending?
I tried with and without and the results seem to be the same.
