I just did a little test. If the passed parameter count is less than the received count (in the UDFs parm list), then the trailing parameters are false. If more parameter are passed than declared in the receiving UDF an error message is pushed.

If there is nothing between the commas the receiving UDF will read the "empty" parameter as a false.

We were talking about this regarding multiple return parameters a while back. You could put the parameters in an object and then verify the state by evaluating what the object has in the store.

This approach would be like creating a long buffer of parameters in order to respond to an unlimited number of parameters being passed. Is that the only way or there is a VB.NET like mechanism?
