Description

The GUI needs to start a separate process for CoCoA-5, and then be able to send inputs to CoCoA-5, and receive outputs from CoCoA-5.

How should this be done (in a portable way)?

I wonder how this was achieved with CoCoA-4.

I do not believe that we implemented any special in CoCoA-4 to enable it; I/O was simply through standard input and standard output.

Yet, I do recall that at least one GUI for CoCoA-4 seemed to know when CoCoA was computing, and when it had finished. How did it know that? Could the old ApCoCoA GUI do this too?
