Empty set

pins forget the empty set

not generally. can you post an example?

pins forget NIL you mean?!?

When i saved the patch, the value of the iobox was NIL, when
i open it the value is 0.

NIL.v4p (1.5 kB)

yeah, and i’m glad that it behaves this way.

if you want to force a NIL you can use the NIL (Spreads).v4p module which is distributed meanwhile.
there is more usage for the AvoidNIL-module btw…
