But you can generate array lookalike stuf like this:

	for i in $(seq 0 9); do
		eval foo_$i=$i
	done

	for i in $(seq 0 9); do
		eval bar=\$foo_$i
		echo foo_$i=$bar
	done

But you can do simple:

	cd /foo
	cd -

But a 'while' loop is often a good replacement.

Yes.  But there are ways to get around that too.
