Re: A86: Input (yes another input question)
Recursive? Are you sure are using the right term? Recursive code is code
that calls it self. It is used for such things as traversing linked lists,
binary trees, reversing data, etc. Did you mean a loop? Also, it is
possible to unroll a loop that is not run for a predetermined number of
times. Anyone heard of Duff's Device (a C thing)?
