Only if called as a function. If called as a procedure they return nothing.

So. If you need a RETURN use the call in function style. Then a perfect designed function should do nothing more. To change parameters is normaly o.k.

If the subroutine should do more then to produce a return value (the side effect is important) it should be called in the procedure style.

But this is all should bubble - I never use DO except in rare cases where I need DO .. IN ..
