Take a look at the maphash, mapwrite and mapread object (icem-www.folkwang-hochschule.de/~finnendahl/pd.html), if the variables have to be accessed by a symbol name or if you want to store other things than simple floats. Otherwise you could use tables (Arrays).

Although the bindings are local to the specified hashtable/table, the hashtable/table is global to pd and thus globally accessible.

If yes: how can I do it

create an array from the menu (and give it a name) or create a maphash object (giving the name of it as creation argument).

and how can I access them?

write-access with tabwrite <array-name> or mapwrite <hashtablename> read-access with tabread <array-name> or mapread <hashtablename>

Hi, Michael Iber hat gesagt: // Michael Iber wrote:

I defined (in self-creating patches) canvas names according to the dynamic-receive-patch, which was posted on this mailing list by putting $0 as the property-name. Is it possible to trigger, send the resulting canvas-number anywhere?

$0 gets the same unique value everytime it is used in a certain abstraction. So if you create a [float $0] along with your canvas, you should be able to send this value anywhere you need it.

All variables (the read-send somethings) are global by default. You have to take special care, if you want them to be only seen locally (use $0) bye,
