>- see footer for list info -< Arguments are not always private to a function. They are only private for variables that are passed by value, reference types are passed by reference and so are not private.
I am not really trying to get a critique of the code. I didn't write it but I have inherited it and was trying to work out the best solution for allowing me to upgrade to cf9 without making so many changes. A little more investigation reveals that you cannot assign anything to local as it will be ignored, so removing the var does not help either.
