For example:

Data A (Where=(X gt 0));
  Do i=1 To 100;
    X=Round(Rannor(1)-0.5,0.1);
	Output; 
  End;
Run;

Wouldn't this just delete those observations instead of just the values for that observation in the column? Why not something like:

if var1 <= 0 then var1 = .;

Can you explain the difference for answering the original post?
