hi list, hi thomas musil, with the iemlib i can take $0-variables as send/receive-arguments. (if i go to the properties and type $0-receive). later, if i open this patch with an editor it appears as /$0-receive. BUT: how can i do this the other way round. iŽd like to edit the name to $0-something in the editor and have it set as $0- in the properties. in this case pd replaces the $0 with a number and i cannot save the patch correctly... in the editor both appear as exactly the same, only when i open the patch, the first stays $0- the other is replaced. or can i create $0 as a symbol(...?) in a pd-patch? marius.
