Thank you all so much, and ++ to everyone who has responded; I actually managed to remember the hashref constructor (and wrap the 'map' statement in it) while I was waiting for the answers. That's a hour or so that I wasted because my brain refused to give that bit of info up at the right time... I swear, I'd even talked to the bear before posting here, and even that didn't shake it loose. Five minutes of having the question up here in SoPW, and down it came. :)

Again, my delighted thanks to everyone - and I'm truly grateful for _all_ the wonderful help you folks provide. An educated sounding board can be the absolutely most helpful thing possible, in the right circumstances!
