Good article, Ian. Ignore those ignorant enough to criticise without giving a reason. And to those who carp about bugs in the code, I say this: Debug it yourself! You'll learn by doing this. Incorrect syntax? Use Books Online to find out what the correct syntax is. Divide by zero error? Put in your own CASE statement to stop this. Carriage returns lost when copying and pasting? Put them back in. Honestly, whenever I post code I'm half tempted to put deliberate errors in it so that people don't just copy it and use it without thinking about it.
