Question

How to use arrays to recode all the numeric variables?

Answer 1

Use _numeric_ and dim functions in array.

data readin;

set outdata;   

array Q(*) _numeric_;

do i=1 to dim(Q);

if Q(i)=6 then Q(i)=.;

end;

run;

Note : DIM returns a total count of the number of elements in array dimension Q.
