OK. I did a little tracing and found both suggestions from Mr. Williamson and Mr. Orr very similar.
The differences, Mr. Williamson's example is more simple. Mr. Orr's example sets the entire _debug function under another if/then statement. The benefit I found with Mr. Orr's example, if the _debug function is a really large function with multiple statements, the additional if/then would prevent reading the large function each time, further wasting system resources. This being the primary goal as well. Other then this, if the _debug function contains only a simple command, Mr. Williamson's example should be faster because it omits Mr. Orr's additional 'else' command.
