I don;t understand the question.
Are you talking about the >>> prompt? 
That is the only place I can think of where expression values 
are displayed without an explicit print statement. In a normal 
script unassigned expressions are evaluated but the result 
is discarded (except for the magic _ variable which is not 
displayed)

But if you refer to a loop when would you ever be evaluating 
expressions inside a loop without assigning them?

Can you give an example of the problem and what your like 
to see? I don;t understand what you are trying to do, or 
where the problem lies.
