Your comments above puzzle me. I have no need to post the URL because
you just did. When I click on the url you posted I go to the routine I
wrote and published myself. It does not mention, point to, and is not
derived from, anything by Ben.

While always a theoretical possibility, it is nigh-impossible in
practice that this will bump into a limit, the default recursion depth
allowing for over 700 directories deep, as Dar has mentioned.

Further, it is a real recursive handler, pre-order, depth-first. The
fact it is a function is normal for a recursive routine which returns
data.




The repeat loops within it simply list the files within the directory at which you have just arrived (pre-order process) and steps through the immediate sub-folders for depth-first recursive searching. What here is "not real"?

Finally, it works without "correction". I know because (a) I just
copied and pasted the code into a test stack and ran it successfully
and (b) it is the code I already use in other stacks anyway; with zero
problems of course.

I appreciate your interest in the topic but not the mis-statements
about recursion or my code.

First let me appologize because you seem to be a bit offended by my statements.
Please forgive me as English is not my native language.
But the part :


< which points to Ben Rubinstein's directory walking function.
Which is not a real recursive handler, but a repeat loop buried in a function.
Only this script as it is, will not work and has to be corrected. >


does not point to you or your code. As a matter of fact your code works perfectly
up to the recursionLimit (I am already sorry for saying this).
It points to the handler of Ben Rubinstein. And I am not accusing him either
(please give me some slack). The problem with his handler is the following line:


if char 1 of x <> "." then
put ("/" & subPath) & return after folders2do #### problem line
end if


If you step trhough the code you will see why.

Then there is the problem of the use of the term "recursion".
A repeat loop is recursive and a handler can be recursive if it calls itself.
But here are 2 different mechanisms at work. And that's why there is a huge difference
between the 2.
So I know the function is using recursion inside the repeat loop but is not recursing by calling itself.
That's why I did call it a non recursive "handler/function". No offense meant.

David
