Both should probably be using the RRR versions (*SYEVR) if I'm reading the advice in the LUG correctly. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco |
