There are some problems for which recursion is the more
elegant apppoach (e.g. code readability)
but "Out of stack space" can be a problem if the stack

Can someone explain to me what recursive subs do. Mu
understanding is
that it is a sub that in effect calls itself. Why would
you ever need
this? What woudl be an example of this?
