When the <em>failhard</em> switch is on, the integration operator
<A HREF=r37_0154.html>int</A>
terminates with an error message if the integral cannot be done in closed
terms.
Default is off.

<P>
Use the <em>failhard</em> switch when you are dealing with complicated integrals
and want to know immediately if REDUCE was unable to handle them. The
integration operator sometimes returns a formal integration form that is
more complicated than the original expression, when it is unable to
complete the integration.
