Thanks Eric, that works fine. Bart's quoting by itself did not work. I
despair of every really understanding -- parsing in my own head -- how
those syntaxes work. I got as close as " ..."${(f) ... " but managed to
drop the ball. Thanks for that link, I had no idea for loops and while
loops were really any different internally, is that widely known?
BTW, is there some way to get typeset to print out just the variables,
not the values? As I read the doc the '-m' switch seems not to like the
'-H' or '+' switches, so it seems I can't have the globed variable name
with no values printed. It seems an unlikely limitation.
