Hi there !
I'm using the message [read resize $1 Audio] just after an Openpanel object to read a sound in an array named Audio with the object tabread4~ Audio.
It's working great and I want to use my patch as an abstraction but I've issue with the use of $0.
I 've named my array $0-Audio, I've writen tabread4~ $0-Audio and [read -resize $1 $0-Audio]. Pd send me "0-Audio : no such table".
I don't understand what I have to write in the message [read -resize] to solve the problem.
If someone could help me for this, it will be nice.

I'm new here, I've created a account just to ask this because I've not found a real response about this in particular.

Message boxes don't interpret $0. Instead, you have to pass $0 to them as an argument.

[o]
|
[f $0]
|
[read $1-array(

Without knowing for sure, you might be able to use the object [makefilename ]

I've used this object before in situations where there's trouble passing a symbol with $0

edit: oops, just see above

[makefilename] will work fine, but in this case there is really no need for it, as you can just put the symbol inside the message box like this:

[200(
|
[pack f $0]
|
[read resize $2-audio $1(

Thx LiamG and LarsXI.
It's working great, just notice that it need to write [pack symbol $0] and [read -resize $1 $2-audio( .
In the same time, I found a great tutoriel for this kind of issue on reddit , it's perfect to really understand how to use abstractions and $0. https://www.reddit.com/r/puredata/comments/7w3yc4/advice_in_building_a_patch_with_different_sampler/
