Oops! I actually knew that but neglected it in my example

AHA! An array worked perfectly for me. Thanks!

I decided to go "all in" on zsh for my scripting, so I'm not worried
about "portability" (not that it's not a bad goal, just one that I've
chosen not to worry about given finite resources of time and attention
and memory, since these are for personal use.)

That said 'zparseopts' has gone into my list of "ZSH Things To Learn"
but for now, arrays for everyone!

Thanks!

ps - sorry for the reply-delay. I've only now had a chance to go in
and try this. Where did July go? How is the summer almost over
already!?
