host <->
call_back: boolWhen @on, a
message sent to the host
object (@prolog)
will immediately be executed. Otherwise it will be stored in the chain host<-messages
for later retrieval by the host language.
Using call_back is the default. Synchronous interfacing (no
call_back) harms the functionality as PCE code and host-language
code will not be intercallable. Sometimes necessary when PCE is
connected to a host language that is not capable of handling callback.
Defaults: @on
(use call_back based interface).
