Too vague.
You can access variables (read *and* write) from any previous scope,
but you don't get to choose which scope. It's always the most recent
one, unless you use "declare -g" to jump straight to the global scope,
as previously noted.
You have access to all of the file descriptors. There is no scope on
those.
