------------------------------------------------------------------------------
 Structure

     typedef struct
     {
        ITEM itmCobExpr;
        ITEM abFilterText;
        BOOL fFilter;
     } DBFILTERINFO;
     
     typedef DBFILTERINFO far * LPDBFILTERINFO;

 Elements

     itmCobExpr / abFilterText

        Contain a code block and a character string, respectively,
        representing the condition that is evaluated at each cursor location.
        If the result of the evaluation is FALSE, the cursor location
        requested is invalid according to the current filter condition.

     fFilter

        Contains a boolean value that is set to TRUE if the filter is active.

     Warning!  You should perform code block evaluations with great
     caution.  Save any states that are likely to change as a result of
     re-entrance, so you can restore them after the code evaluation.
