Checking arrays for any values

In CF9, Adobe have (finally) added the ArrayFind function, which simplifies that
code.
(Also available in OpenBD v1.3 and above, and in Railo since early days.)

You can do listFind(arrayToList(aYourArray),1) for the bit datatypes. I'm
not sure what the performance of that will be if your array is very large,
though.
For the string array, you can do NOT listFind(arrayToList(aYourArray,""))
I'm not sure if that logic is exactly correct, but it should get you going
down the right path.

It's not clear what you're trying to do.
Can you post examples of each type of value it might contain, and whether that is
considered true/false?
(It's probably still simplest to step through the array and check each value
though.)

If any of the elements of an array have a value of 1 for bit datatypes or don't
have empty strings for string datatypes, then I need to have my program do one
thing, otherwise, if everything is either empty or false, another thing. I could
parse the array and get their values, but I wonder if there is an easier way.
Thanks in advance.
