Data tbl;

1 5
2 .
2 .
2 3
2 .
2 .
3 .
3 .
3 .
3 .
3 .
;
run;
/*Required data set*/
/*1 .  3,5*/
/*1 .  3,5*/
/*1 3  3,5*/
/*1 .  3,5*/
/*1 5  3,5*/
/*2 .  3*/
/*2 .  3 */
/*2 3  3*/

data want;
    do until (last.id);
        set tbl;
        length con $ 200;
        by id;
        if not missing(Loc) then con=catx(',', con, Loc);
    end;
    do until (last.id);
        set tbl;
        by id;
        output;
    end;
run;

Result:

ID   Loc   con
1          3,5
1          3,5
1    3     3,5
1          3,5
1    5     3,5
2    3
2    3
2    3     3
