Hi again - just had another look at your question, I notice that you just
refer to "processing arrays". You picked an example that uses looping but
you can wrap any AFL in a function, you don't need to use looping unless you
really need it...Thnk of the function as sort of a container - it will
basically hold any code that you could just as easily put inline, not much
reason to use one I don't think unless you want to call the code from
several places or it is part of some larger organizational scheme...
