note brusimm Thank you Andrew. <p>The simpleness of your explanation does make it a more graspable concept to ponder. I think a node should be created for those of us who are new to Perl and semi new to programming and need things spelled out more verbosely. <p>Everyone here is great, but they come from a very knowledgeable perspective that doesn't understand, not understanding.. <p>I wonder who we should ask? But again, thank you for your perspective. 589388 589388
