You need to specify which variables you want to keep in data sets a and b. Add keep statements to the data step:
>data a (keep=i x y) b (keep=i x z);
> set k;
> if i in (2, 4, 6) then do;
> y=x;
> output a;
> end;
> else if i in (9, 10) then do;
> z=x;
> output b;
> end;
>proc print data=a;
>proc print data=b;
>run;
