Example 9-7. Calling a process from a process, and reporting the results

defmodule MphDrop do def mph_drop do drop_pid = spawn(Drop, :drop, []) convert(drop_pid) end def convert(drop_pid) do receive do {planemo, distance} -> send(drop_pid, {self(), planemo, distance}) convert(drop_pid) {planemo, distance, velocity} -> mph_velocity = 2.23693629 * velocity IO.write("On #{planemo}, a fall of #{distance} meters ") IO.puts("yields a velocity of #{mph_velocity} mph.") convert(drop_pid) end end end

The mph_drop/1 function spawns a Drop.drop/0 process when it is first set up, using the same module you saw in Example 9-6, and stores the pid in drop_pid. Then it calls convert/1, which will listen for messages recursively.
