Re^2: Best Practice: How do I pass option parameters to functions? (warnings)

Just the header I've copy/pasted into my scripts ever since I started using perl. I'd thought about changing it, but, quite honestly, I'd completely forgotten about it when posting the question. Thanks for the clarification of the differences, though!	[reply]
