To make clear my problem, i will try to describe my current project:
I have 2 electronic devices which each is controlled by a pic. The first electronic circuit sends transmitts data via rs232 to a radio module. This modul sends the data to a 2nd radio module which receives the incoming data and transmitt it via rs232 to the 2nd electronic circuit. This circuit handles the incoming data and sends it back to the 1st electronic circuit.
I hope everybody is able to understand my description

Now, here is my question:
Is it possible to communicate between the two different source codes without a existing hardware connection?
Is it possible to use or to import/export variables from program x to program y?
If yes, how can i manage this?
