First of all, what is Axe 1.2.5 ?

Next thing, the getKey routine sucks. Using getKey(#) is a lot faster. But I xan see why you need the basic getKey command in your program so don't change it if you don't want

Also, the Copy() command copies from one pointer to another and needs a size argument, so yours should not work, and even with a third argument, it won't work. I guess what you want to do is K→L1(A) but it won't work either, see next point

Finally, the L1 list doesn't exist. L1 is a pointer to some free memory location.
You need to replace all your L1(A) by {L1+A}
This should work then

[edit] I didn't see it two minutes ago but you are using Ans, which is not an Axe variable.
Just replace this
 Repeat Ans
 getKey→K
 End
by this
 getKey^r
 →K
or this
 0
 Repeat
  getKey
 End
 →K

Thanks, really appreciate it

No problem. Omnimaga is really the place to be if you need help with Axe. I got help too when I needed it so I am just giving back ^^

Also, I edited my post like 9 times, not sure if you saw the last version of it.

Moreover, I only think of it now but {A+L1} is more optimised than {L1+A}

Yea, mistake on my part, also thanks , Finally No, I do move quite often between them, about very few months. Also do you think you can tell me what's wrong.

Now I have the lists (L6), and put data in it with K->{B+L6}. However it doesn't seem to actually be put in the list?

Whoa, did not know that. should I use L1 instead then?

Hmm, i'll try to do a custom list then. But when I do say LKEY, it says it doesn't exist?

Oh, okay then, is it possible to create something with Buff that is permanent?

Something not in program memory, something that can be accessed from multiple programs?
