In SAS High-Performance Risk 3.8 and later, it is necessary to use the NOSYM option to avoid truncated output arrays from risk functions (call routines) if they have a length longer than the declared length.  Otherwise, these arrays are truncated to the declared length.  The NOSYM option in the array declaration indicates that the array is dynamic, and the array might have a length longer than the declared length. In project runs, if the output array has been truncated, the log includes a warning.  

An example of using the NOSYM option to declare dynamic arrays follows.

proc compile env=envlib outlib=envlib;
   method instave kind=computed;
      array ranked_vals[1] / nosym;
      array indices[1] / nosym;
      call get_ranked_values('VALUE', ., ranked_vals, indices);
      n = dim(ranked_vals);
      sum = 0;
      do i=1 to n;
         sum += ranked_vals[i];
      end;

      xmean = sum/n;
      instave = xmean;
   endmethod;
run;
