The use of "( ... )" to comment-out large blocks of code is fairly
dubious anyway, since most code has interspersed comments, and most
implementations of "(" do not nest.

On the other hand, "( .. )" could be entirely enclosed inside
"IF( .. )THEN" with no ill effects, e.g.

        IF(
           OVER +   ( n1 n2 )
        )THEN
