[Gambas-user] Send data to the process

[Bruce Steers]

Dear oh dear i should have read your first message properly to begin with
lol.

I see you have communication going one way just fine,
so all you need is for app2 to have a pipe file to watch then after app2
sends the message to app1 the app1 can then echo the result to the pipe
that app2 is watching.

Hope that makes sense
