How could I format the variables under ID in Class 4 to have the number variables be labeled with 'ID' like the ones in Class 1, Class 2, and Class 3 using SAS?
data sample;
length idwant $18;
do id=1 to 5, 99 to 101;
if id<10 then
do;
idwant=cats('ID',put(id,z2.));
end;
else
idwant=cats('ID',put(id,best16.));
output;
end;
stop;
run;
