The flowgraph randomly generates a code, which the player must find and type in to the console. This is done by pressing F on a screen to proceed to the next number. The submit button is then pressed, and the flowgraph verifies whether the code is correct or not. The system was built for the WIP Fickle map, more information can be found in the Crymod forum thread here. crymod.com/thread.php?threadid=26174
