  This is in the actual program - I have a filter set to allow them to 
identify
  records in their catalog that have a blank comment and edit those 
comments.  If
  they add a comment, it would disappear from the list, so I save a 
list of pointers
  to a reasonable extent so that the edited records will remain in the 
list.

  I still get the error message with either statement.

  Accept := ((Trim(CatalogTable.FieldByName('Comment').AsString) = '') 
or in_pointerarray(CatalogTable.FieldByName('Tag').AsInteger));
*)
  Accept := (Trim(CatalogTable.FieldByName('Comment').AsString) = '');
end;
