You're right, Steve, this does work, and the whole script now works 
according to plan.
I know you are busy with the Library Display, so only reply (if you feel 
like it) when you have a moment at some time in the future.
You ask if my script is "young".  What does that mean?  It's about three 
days old, and hasn't yet had a birthday - I think I started it on Sunday.
What is sh/perl?  You ask if I like it.  I know that perl is a 
programming language.  I've used several in my time, including C at an 
elementary level, Basic in several forms, and I've written search 
programs in compiler (PSH X, NOP, etc.), so I probably would like it.
Can I suggest a future meeting include some workshop time, run by one or 
two of us who are good at scripting, so non-experts like me can be 
improved and have chance to ask questions.
Another meeting workshop might include vim.  Al's really gd at that.
Woja think?
Thanks for all the help!
