That is the error you get when using /bin/sh (aka /bin/dash due to the
symlink).

Nope, you are wrong in this case. I tested that array code on three
physically different Ubuntu Systems (8.04, 9.04, and 9.10
beta) as well as my 64Studio 3Beta system. *All* systems passed (ie.
they worked the same and as expected all of the machines handled the
array properly). I have not installed nor built a custom version of
bash, I used whatever version the distro came with.
Please execute those lines one at a time, do *NOT* put them in a script.
This is what I mean about testing. Keep it simple and break it down.
Then if you get no errors, you can put them in a script. Make the
script(s) executable with chmod u+x <scriptname> then ./scriptname to
run the script. Do *NOT* preface the script with sh, this will force
your OS to use /bin/sh regardless of the shebang line at the top of your
script. /bin/sh is a symlink to /bin/dash which does not support arrays.
