I may be missing some deeper nested (no pun intended :) point, but how is your factorial_iterative() interative? Inside you simply make a call to fi_helper() which is a recursive subroutine.
An interative routine would be the one which didn't make a call to itself and instead used loops to complete the task (as some of other commenters already did). (ps: the subject of this thread is great and I enjoyed reading both your and other monks' posts :) update: mvaline, ahh that makes sense now ;-) Thanks for your reply. _____________________ "We've all heard that a million monkeys banging on a million typewriters will eventually reproduce the entire works of Shakespeare.
