[AccessD] Function vs Sub (was: Classes and Events - EVENTS NOT REQUIRED)

Hi Stuart

That's a nice old story. However, it fails because it defines sound as being dependant on both a transmitter and a receiver. A sound transmitter (speaker, siren etc.) will continue to produce sound even if a receiver is not there; in that case the sound energy is absorbed by the air surrounding it or ultimately by the surroundings and turns into heat. That tells further, that no _air_, no sound. So no transmitting media, no sound. Thus everything in outer space is silent, which is why all the roaring and noise from the spaceships in Starwars is nonsense. But who cares. One Silent Movie is enough!

Now we are getting philosophical :-)

"If a tree falls in a forest and no one is around to hear it, does it make a sound?" 

Answer??
"Sound is vibration, transmitted to our senses through the mechanism of the ear, and 
recognized as sound only at our nerve centers. The falling of the tree or any other 
disturbance will produce vibration of the air. If there be no ears to hear, there will be no 
sound."  

x= myFunction() demonstrably returns an Empty Variant

does "Call myFunction()"  *return* anything? If so, where to?

Cheers,
Stuart (aka Bishop Berkely)
