I'm not sure I would call what you are describing FP, because I'm old enough to remember when it was procedural programming, and it was a very common pattern among people that didn't quite get the whole OO thing yet when the moved from C or Pascal to Java. The main difference, really, would be whether you just poke at globals, or thread them through.
