BTW, you don't need the quotes. The assignment is parsed before the
values arrive. Eg, this works:
x='a b c'
y=$x
Also, just for other scripts, this:
foo=`command`
is more portable than
foo=$(command)

They keep talking about drafting a Constitution for Iraq. Why don't
we just give them ours? It was written by a lot of really smart guys,
it's worked for over 200 years and we're not using it anymore.
