Summary table based on rows

[SasStatistics]

I have the following data: 

ID	flg1	flg2	flg3
60038807	1	0	0
60038807	0	0	0
60038807	0	1	0

Now I would like to "summarize it" so it looks like this: 

ID	flg1	flg2	flg3
60038807	1	1	0

So one row with a "1" in all columns where it has a 1.

proc summary data=have nway;
    class id;
    var flg1-flg3;
    output out=want max=;
run;

You don't really explain what you mean by "summarize" so I have chosen to compute the maximum of your zeros and ones. If you want something different, you can just change the statistic in the output statement from max= to any other statistic you want.
