actually, I just checked my answer again, and when the list has two elements, it outputs a list of three elements on subsequent runs, as the 100 was still part of the list...
Is this one more accurate?

ok, well sorry. I just take the assignment as it, where you wrote "a list" and "too short". Thought you were making teh statement general, and lists were here just as example. anyway, that was fun playing.

You're right in that the length of the list in the assignment is an arbitrary choice and ideally a solution would extend to larger lists as well. But any solution would have to be adapted to a certain list length. I guess at least, but maybe someone proves me wrong? ;)

So cool in fact, that it's now part of [list]-abs, where I called it [list-pad]. It's in the SVN but also attached. Thanks a lot.

It occured to me that the crossconnecting in the first attempt was a bit silly, so the version that's in SVN now uses a more tradional approach with a cold right inlet to set padding values and no right outlet.

If I understand you correctly on this, Thomas, if it were "settable", wouldn't each use of that [pack] reset the values that it would use for the defaults? I thought that was the whole point of the problem?

Hey all,
I was trying to do this dynamically with the lowest possible amount of objects and I found a surprising behavior of [list split]:
Connecting a patchcord back from the second outlet of [list split] to its first inlet puts out all elements of a list in reversed order of the first outlet.
I know that's neither effective nor the right way to patch in Pd, but perhaps someone can explain that?
cheers, Martin

it's surely a consequence of "depth first" (see pd help examples)...
the message output from the second outlet retriggers and alters the
state of the "list split" before the message is output from the first
outlet. I guess that quite a number of pd objects are not re-entrant
(including most of mine).

Yeah, that's a real good example for depth first (and also for recursive functions on lists)! If you change the outlets oft the [t a a] also the order of the printed list switches from reversed to not reversed. Good to know!

Marius,
Wasn't quite sure if this would work, so I implemented it, and found that, maybe do to this "ascii" version, that the [pack 0 100] should be connected to the right outlet of the [list split 2]... This appears to be the shortest implementation.
Just mention this so others would recognize this...
I attached that version...

Of course I can't participate in my own exam. ;)
The idea for this task actually comes from real life patching:
I recently had to patch this little idiom myself (or rather the harder one from the new Exam 02) when doing a sample player which accepts lists composed of:
<table-name> <gain> <speed> <start position> <duration>
I wanted to provide defaults for all parameters except the table-name: gain=1, speed=1, start=0, duration=0 (for "play all").

Frank Barknecht
Based on the same patch i send before (ex. 2). I know this not the shortest solution :) ++
