Paul, CFSwitch I believe is faster (slightly) , and I think easier to read. Also, the default case does not need to be the last case (as opposed to an ELSE statement). However, the tradeoff is that the case values have to be contstants.
For IF statements, the benefits are the possibility of dynamic comparisons (ie. URL.x EQ URL.y ). Mostly though, it's a matter of personal preference I think. Cfset sets a value into a variable. Cfparam checks to see if a variable already exists. If it does not exist and a default was provided, it sets that value into the variable. If no default exists, it throws an error. I think there are a lot of different opinions on why/when it is appropriate to use CFParam vs setting a variable. I like to CFParam all my FORM variables and custom tag ATTRIBUTES (as an example). I like to know that a value exists, even if it isn't correct, because then I can validate afterwards. However, in Custom tags, I ususally don't have default values for all my attribute params so that CF will throw an error if the user does not provide the attribute. If by variable pools, you mean scopes (ex. APPLICATION, SESSION, REQUEST), they are fantastic! I scope (define within the context of a "variable poo", ex. FORM.first_name) anything that is either submitted to a page or is available in more than one template. So for example, if I use an index variable that is for only one template, I might use intChild, but if I use a variable that is set in one template and used in another, I might use something like REQUEST.ChildIndex... It becomes a naming convention that I love because the structure of the variable helps explain what it is and where it was set/available. There is lots to know about the different scopes and how widely accessible they are. Check out the main ones in the live docs. .......................
