NOLNR _ _ _ _ _ _ _ _ _ _ _ _ switch

When nolnr is on, the linear properties of the integration operator int are suppressed if the integral cannot be found in closed terms.

REDUCE uses the linear properties of integration to attempt to break down an integral into manageable pieces. If an integral cannot be found in closed terms, these pieces are returned. When the nolnr switch is off, as many of the pieces as possible are integrated. When it is on, if any piece fails, the rest of them remain unevaluated.
