Hi Matz,

Yeah, I've seen that defined? gives me results I'm not really looking
for...kinda like the isset() versus empty() functions in php...I've since
changed that script to use a simple 'if table' test which works beautifully.
I have to say, ruby really does stick to the POLS well...its been a joy to
program in so far, and its been about 2 days :-)
Thanks for your 'rubies' of wisdom (ok, its 3:20am, i'm excused from that
one...)

Jack

Don't use defined? for local variables like this.  Determination is
done in compile time, so that result may be different from your
expectation.
