I wonder if they were looking for (**) instead of (^).

Haskellers, I have an external dll which in some particular cases crashes.
Basically first I need to send to my dll with MethodA some parameters and
then call MethodB to do some calculations on those parameters. If I didn't
give enough parameters then MethodB will crash the whole dll. Is there a
way to handle this? Unfortunately there are no exceptions thrown from the
dll.
In ghci I'm getting following message: ERROR in
InitNumericalSystem::initializeSystem. JuncLabel.
cheers,
m.
