You have now posted this same question on five different threads? Please indicate which thread you us to answer by marking the others as "answered."

And, as I said before, the READ stmt is wrong. I cannot run your code, so please give the result of PROC PRINT on the FCOV data set.

If FCOV has the same number of rows as it has numerica columns, you want to write

use fcov;

var all var _num_ into O;

close fcov;
