Good evening all
is there a way to assign an index to a series of sublists or elements contained in a list? For example: ((0 2 3) (6 11 9 7 ) ( 8 5 ) (1 4) (10))
(0 2 3) = a
(6 11 9 7 ) = b
( 8 5 ) = c
(1 4) = d
(10) = e
Thanks for your help

Dear AB
Yes of course. There is a Lisp mechanism for that:
and here is the patch:
indexed_sub-list.omp (3.2 KB)
I hope that what’s you were looking for.

Hi,
I was going to figure how to do that ! And here it is ! Thank you both !
Still Karim, as you can see on the attached screenshot, there is an error while evaluating… kind a curious.

Yes dear Nadir, this is due to the usage of symbol. It’s always problematic.
But how about this?:

Thanks for your reply Maestro,
I hope this does not scramble Able thread, otherwise I will open another one.
The index is very important because I want to compare items in multiple sublists and then have as a result the indexes of the sublists that include a given approximation of an item, i.e. let’s say I have :
list 1 : ((a1) (f1 f2)) ((b1) (f’1 f’2)) ((c1) (f"1 f"2))…
list 2 : ((a2) (f1 f2)) ((b2) (f’1 f’2)) ((b3) (f"1 f"2))…
…
list n : ((an) (f1 f2)) ((bn) (f’1 f’2)) ((cn) (f"1 f"2))…
Input : fn
If fn is included in list1 or/and list2… or/and listn (even if it is an approximation, I know I have to constraint that approximation)
Outcome : The index of that list
What do you think, any hint please 
Thanks again,
N.
Outcome : The indexes of any list including that Input
Thanks Karim !
Well, I want it the other way around i.e. from the example above :
input = (6 11 9 7) → output = b
And even : input : 6 or 11… → output : b

That would be so practical to have all these lisp-fx documented, I could spare some time to help if ever… At least we can already retrieve them thanks to your tab-completion addon !
Yes something like that ! Thank you Karim.
And thanks to Able for bringing the question.
All the best,
N.
