Communicating Programs
In order to communicate with one another, two programs need a third one interconnecting them.
As a rule, the communication is partial. Neither program is aware of every activity of the other. Parts of program A interact with parts of program B, thus establishing a connection. In this way a new program C is formed. With its own space.
The program-spaces penetrate one another, their superposition is a space of its own. Although there is no sharp distinction. Localization in one space does not exclude localization in any other. But of course there are many things occuring only in one of those interpenetrating spaces. Each space is in its way unique.
