Hallo, Georg Werner hat gesagt: // Georg Werner wrote:

can somebody explain why there is a "3rd rule of $-expansion: 'there is no $0 in message-boxes'". i stumble every now and then about it and it is IMHO not self-explanatory. it is not hard to implement and wouldn't make problems with existing patches - because $0 is never used in messages. and would make things easier not only for beginners.

Actually this topic is discussed about once or twice a year on pd-list and pd-dev, so for deeper info check the archive.

Anyway: $0 is a property of the surrounding abstraction or canvas, as are $1,... in object arguments. The $1,... in message boxes however are properties of the messages sent around and reaching a message box. While the value of dollar variable in message boxes changes all the time, the value of the canvas-dollars never change.

Messages don't have anything comparable to the canvas' $0.

A possible alternative use for $0 in messages would be the selector ("list", "symbol", ...) as that is the thing before $1, but implementing that could be even more confusing to beginners.

Ciao
