   Messages between apps?
  Hi there i am trying to work out how i can successfully pass vars between two different applications.One app is programmed by me using LUA and the other app has full access to lua but i cannot find a way to pass data to one another?How can i do this or what is there "correct" way.I tried having a single lua file with the vars in there, one app repeatily daved it whilst the other loaded it but it doesnt always sync right and somtimes crashes which i put down to the file only being half saved when it being tried to be loaded by the other app.Any ideas?ThanksAndy   
  There are many ways to do it.  Search Google for "Inter-process Communication" and "IPC".Normal ways of doing it include OS messages, OS semaphores and signals, shared files and pipes, shared memory, (network) sockets, and dedicated communications APIs.Some of the obscure (but still successful) ways of doing it include signaling data through measured CPU load, system temperature, resource availability, and more.  You probably don't want to go through any of these routes, but they are certainly available.
