int operator >=(
   const CXlOper& xlo
) const;
An initialised CXlOper, or a reference to CXlOper.
Returns TRUE if the value in this object is greater than or equal to that in xlo;
            returns FALSE otherwise.
Note that CXlOpers are sorted by type first and then value. 
            Thus a string containing "123" will not necessarily sort later than 
            an integer containing 122. 
            For CXlOpers of the same type, sort order is always by value.
