Passing of value from one separate application to another

Question

I'm looking for advice and experiences about proper way to create outputs from one separate application to other independent application which must take this value for own implementation conditions. to make it clearer in primitive way for example output application writes some undated value to the text file, and another running application with available path to this file reads it in time loop and if value is found makes some implementation. But I'm trying to find what is more correct way to do the same to pass it from one application directly to another

Message Queing is certainly what you are looking for.

It will let some applications put messages on the queue and some others (or not actually) consume these messages.
