Syntax

BROADCAST: group class code ;

Inputs
None

Outputs
None

Word description
Declares that objects of class will delegate the generic words contained in group to every object in the sequence returned by executing code with the original object as an input. BROADCAST: will overwrite any existing methods on class for the members of group, but new methods can be added after the BROADCAST: to override the delegation. Every generic word in group must return no outputs; otherwise, a broadcast-words-must-have-no-outputs error will be raised.
