[PD] array read -resize according to file ?

If you need [array] or [table] to do operations on them, you could use :
[text define] to load your list of float,
[0( on [text size] to get the number of float in your text file.

Then use this number to resize your [array] and then load your textfile
in this array.

I don't test it, and maybe there is a more elegant way to achieve this.
