Not a bad thing, but not what I'm needing for what I'm trying to do :).

Actually, this was just a test script to figure out how to get the "while
read" to work. The actual script did something else entirely. Sorry for not
making that clear.

I've fixed it by just taking a line at a time and pulling out the items I
need. I could probably do it better with awk, but what I have is functional.
However, it still doesn't explain why read causes while loops to end up with
local instances of the variables that lose scope upon exiting the while
loop.

That's really what I'm trying to learn.

danke,
