Not proven; you cannot assume this. One school of thought about programming is that all functions must have only one return and all programs must have only one exit. Therefore, help() may return or it may not. Until you actually see the help() sub, you don't know if it returns. -- Just my 0.00000002 million dollars worth, Shawn Programming is as much about organization and communication as it is about coding.
