how can I store multiple result once a time?

[Haitao Yao]

Hi , all 
        How can I store multiple result using one store function? 
        for example: store Result1, Result 2 into '/tmp/result' using 
PigStorage(',');

        the default store function does not accept multiple parameter as input .

        thanks
