Right. Which neatly brings the question back around to "why can't $0 be
used in message boxes?" I've said this before (to no avail): it is well
understood that $0 has no meaning in *messages* -- however, this is not
a good reason why $0 can't be used in *message boxes.*
Since "1024-foo" (where "1024" represents the canvas-identifier), *does*
have meaning in messages, why must we jump through (admittedly minor,
but still quite annoying) hoops just to get that canvas-identifier into
a message?
It probably belongs in the "some things will never change in Pd"
category; therefore we must resign ourselves to this discussion
re-appearing on a regular basis.
