Here is my sample dataset

And I would like to create a 2 dimensional array like this

Hi and welcome to the SAS Communities 🙂

You can do like this

data have;
input row col num;
datalines;
1 1 1
1 2 2
1 3 3
2 1 4
2 2 5
2 3 6
3 1 7
3 2 8
3 3 9
;

data want;
   set have end=lr;
   array MyArray {3, 3} _temporary_;
   MyArray[row, col]=num;

   /* Verify that the values are correctly assigned */
   if lr;
   do i=1 to 3;
      do j=1 to 3;
         put (MyArray[i, j])(=);
      end;
   end;
run;  

This prints

Do you have IML ?

data have;
input row col num;
datalines;
1 1 1
1 2 2
1 3 3
2 1 4
2 2 5
2 3 6
3 1 7
3 2 8
3 3 9
;
proc iml;
use have;
read all var {row col num};
close;
x=num||row||col;
have=full(x);
print have;

quit;
