message <- arguments: code_vector|any|function*

Vector of arguments to pass to the send-operation. When @nil, no arguments are passed. It is a code_vector object because it should allow the elements to be function objects. See also message->initialise and message<->argument.

message <- context: any*

The context slot is reserved for cooperation with function-based modularization. For Prolog, it contains the module from which the object was created. If the object is executed, this context argument will be used to resolve the proper function. In Prolog:

?- new(X, foo:message(@prolog, hello)),
   send(X, execute).

will call the predicate hello in the module foo. See also’?message<-_context’and rc<-context.
