Hi Todd,

*>* huge number with 100% tolerance. Is there a better way to do this other
*>* than with the numerical response code here?
*
Currently that is probably the best way for now. (Id' go with an
answer of zero and a large absolute tolerance, but ...)
There is a half finished response type <dataresponse> which might have
been more approriate, but the numerical response seems to work good
enough.
