Intriguing topic of discussion! :-) I suspect an "IPC specification" of sorts for ooRexx would be necessary in order to allow the ooRexx environment to participate with an external language in two-way dialog. I was off pondering similar things when I was contemplating my ooRexx Application Server Architecture which would be grid-aware. To allow ooRexx to be grid-aware, an IPC of sorts would be necessary between what controls the grid and the core of ooRexx (RxAPI perhaps). Also for my grid-aware ooRexx thoughts, it became apparent that the ooRexx code (RxAPI) would have to become itself grid-aware, deciding which node(s) to spin tasks off to, which node has a particular object in its memory, etc... Since nothing is even remotely prepared for such in ooRexx, I decided against such a design and was contented to having the architecture start disposable instances of the ooRexx interpreter to execute something on the architecture's behalf, and once finished the ooRexx interpreter is destroyed / cleaned up.
