To facilitate communication between processes, most operating systems support Inter Process Communication (IPC) resources, such as pipes and sockets. IPC is used not just for communication between processes on the same system, but processes on different systems.

Your requirement of not using a file to store information if the second program is not running would make for a little more challenge. You could identify if the connection is not available and if it is not save the value in a collection until the second program is up, but then you would handle the recognition of when the other program comes up. You would also need to determine when to do this check. Would it only be after each value is entered or would you have the first program looping waiting for the second program to appear. Of course, if the first program is stopped, the second program will not be able to get the values entered into the first program.
