Yes, very good points. In particular, I hadn't thought about there being code that might modify $name. Thank you!
I guess I do focus too much on the details because I'm still at an early stage of learning and I try very hard to understand exactly how everything works, but don't have enough knowledge/imagination to see how the example being demonstrated might be used in real code. Hopefully as I write more real code it'll be easier to understand these things! __________ "Abby-somebody. Abby-normal." Young Frankenstein In reply to Thanks, Re: Using scalar values as conditionals
