[Gambas-user] Send data to the process

[Bruce Steers]

Sorry i missed the bit about feedback.
for that you could make both apps have a pipe file and they can send and
receive data to each other
So App1 sends "multiply 2x2" to /tmp/App2_pipe
Shell "echo 'multiply 2x2' >/tmp/App2_pipe"

Then app2 send the result to app1
Shell "echo 'MultiplyResult=4' >/tmp/App1_pipe"
