Thank you both very much for the explanations. So if I got it right, the loop in itself was behaving as expected, but what was being printed in the console was not reflecting that. Instead print behaved like a list prepend.
That's good to know, I candidly thought that print objects were printing out stuff in real time irrespective of what was going on in the rest of the patch.

Cheers,

Pierre.

You need to trigger the print before the recursion branch.

Because you have the print _after_ the recursion branch, the prints can only get triggered after the complete recursion has stopped.

That's why the output is reversed in order.

Take a look at pd manual: 2.3.2. depth first message passing

Cheers,

Dear list,

I just ran into something very odd while trying to parse a string to
extract a filename from a path with [list fromsymbol].
Please look at the patch attached. I try to loop backward through the
fields of a line in a [text] object to find the first "/" (code 47).

When I do it "manually" (load the list and get the last field, then
decrease the counter with a bang until I reach the last "/", everything
works fine, and the counter starts at 17 and goes down.

But when I try to automate it by checking if the output equals 47 and by
sending a bang to my counter when it's not, I get a very strange result.
The counter actually starts at the last occurrence of "/" (47) in field
8, and then goes up to 17.

I am probably very tired and I must be missing something obvious. But
right now this looks like aliens have hacked into Pd and are playing
with my nerves.

Thanks in advance for your help,
Pierre.

PS : I've been using the new text and array objects and I think they're
very useful, though not always super intuitive.
