You change your IB_Query parameters (FieldsGridLabel or
FieldsDisplayLabel). IBO is data driven, so there's nothing for you to
change on the TIB_Grid.

I haven't got a clue, never needed them (I think).

The important difference between IB_Cursor and IB_Query is that the cursor
is unidirectional. You normally want to be able to scroll both ways when
using a grid which makes IB_Cursor useless. While I agree that a useful
error message would be an advantage, I don't recall this causing me any
trouble in my early days as an IBO user.
