Yes

>IAC, as the code stands, the TRY/CATCH block in retParm() is redundant since you're not handling the exception in any meaningful way.
That is the point. I want to handle the error in the completewhere() method. My interpretation of the docs says that throw will throw the error to the calling method's error handler????
