When creating a flight plan VIA the F-10 map, what is the proper abbreviation for the landing WPT?

Hello all, 

The title says it all. When creating a flight plan VIA the F-10 map, what is the proper abbreviation for the terminating waypoint or landing airfield? I'm asking because, without a termination point, the last WPT points back to WPT1. I know this is pretty nit-picky, apologies ahead of time.

just whatever your last WPT is, that's where you should land. It will load all the airports by order of distance from the last WPT.

Thank you.
