Thinking about it, it probably makes more sense to initialize to 0 because
that is a valid value for either a string or a number.
I guess I use "" because it is the closest that you can get to a null in CF
(short of something like chr(0), but that doesn't feel too good either) and
it's how CF brings back NULLs from a database.
This is heading off rapidly into the world of curiosities and probably
doesn't have much bearing on the readability or maintainability of anyone's
code, but I always like to know 'how other people are doing it' for a sanity
check of my own approach if nothing else.

Yep...
Incidentally, does anyone know if CFFTP is a full scope or a normal
variable?
CFHTTP is a normal variable, so you can make it thread safe, but CFFILE
isn't.
I have never checked any of the others like CFPOP, CFDIRECTORY, CFSEARCH
etc. Has anyone else?
