int input [int]
In left inlet: The number is either added to or deleted from the collection of numbers stored in the bag object, depending on the number in the right inlet.

In right inlet: The number is stored as an indicator of whether to include or delete the next number received in the left inlet. If non-zero, the number received in the left inlet is added to the bag. If 0, the number is deleted from the bag.

No output is triggered by a number received in either inlet.

clear In left inlet: Deletes the entire contents of the bag.
cut In left inlet: Sends out the oldest (earliest received) number stored in the bag object, and deletes it from the bag.
length In left inlet: Reports how many numbers are currently stored in the bag.
send receive-name [list]
In left inlet: The word send, followed by the name of a receive object, sends the result of a bang message to all receive objects with that name, instead of out the bag object's outlet.
