• The CorbaScript Language: CorbaScript is an interpreted object-oriented scripting language dedicated to CORBA environments. Scripts (i.e. CorbaScript programs) can invoke any operation, get and set any attribute of any Corba object. Moreover, any OMG-IDL interface can be implemented by scripts. CorbaScript provides a dynamic binding to OMG-IDL descriptions: no OMG-IDL stub or skeleton need to be generated.
