A request is either of the form Getq, indicating a character should be read, or of the form Putq c, indicating that character c should be written.
echoD.d :: Dialogue echoD p = Getq: case p of Getp c : p' [right arrow] if (c == `\n') then [] else Putq c: case p' of Putp : p" [right arrow] echoD p" The program first issues the request Getq on its request stream, indicating a character should be read, causing the response Getp c to appear on its response stream, indicating character c was read.
echoD (bottom) = Getq :bottom echoD (Getp `A':bottom) = Getq :Putq `A':bottom echoD (Getp `A':Putp :bottom) = Getq :Putq `A':Getq :bottom echoD (Getp `A':Putp :Getp `B':bottom) = Getq :Putq `A':Getq :Putq `B':bottom) echoD (Getp `A':Putp :Getp `B':Putp : Getp `\n':bottom) = Getq :Putq `A':Getq :Putq `B':Getq :[] echoD (Getp `A':Putp :Getp `B':Putp : Getp `\n':[]) = Getq :Putq `A':Getq :Putq `B': Getq :[] This view restores the causality: first there are no responses and the request Getq is issued; next the response Getp `A' appears and the request Putq `A' is issued, and so on.
