run;
proc contents data=a out=out(keep=name); run;
proc sql noprint;
select name into: name separated by ' ' from out;
run;
proc transpose data=a out=b;
run;
data c; set b;
missnum=nmiss(of col1-col4);
run;
data d(where=(missnum=0))
e(where=(missnum>0));
set c;
run; |

make a small data set to record all the missing value variable name
de-duplicate the small data set
outer left join
transpose back
how is this
