Thank you liverpole. I will indeed take this approach. Regarding strict and warnings, I do use the latter. I've tried the former but don't understand it very well. As a result, I end up using it very badly.

I'm having a tough time getting my mind around what 'use strict' does (though I'm busily poring through various FAQs I can find to sort it out). Any good/understandable-for-the-newbie links you happen to know on the subject will be most appreciated!

As a "for instance" regarding my lack of 'strict', whenever I use an array where I've specified 'strict', I have to refer to it during the rest of the script as main::@whatever. I'm sure that's not the right way to approach this, but I haven't found a better way to do this.
