I know I have read about this, but I have forgotten.

I have an abstraction with an array (array1),
but I want to use multiple instances of that abstraction in my main patch,
and that gives me a warning about array1: mutiply defined

How do I do automatic naming or how to I hide array1 from the instances, so that it does not get confused?

Just prefix anything unique in a abstraction with $0.

Yeah, I found out.
Thanks..

But now a different problem occurs.
Since, I read that messages don't understand $0 directly, and I have to put it in an object first.

But I also have different data coming to the message, like i.e.

I have an array called $0-array

[expr 1*2]
| [$0]
| \
[pack f f ]
|
[;
$2-array resize $1(

But that does not work.
I get 0-array no surch object.

Think I figured it out now.
And I would attach my patches, if I knew how to.
