in reply to Recursion Confusion

G'day live4tech,

You don't say where you got these subroutines from but the originals (except for an errant factorial line in the first) come from Mark Jason Dominus' book "Higher-Order Perl" (see his home node for links to various versions). A description of recursion starts at the beginning of Chapter 1; section 1.3 describes the Tower of Hanoi puzzle.
