As I was reading the FS2002 Panel and Gauge SDK, I saw in the Flight Map sample that they are using a named variable called "FS2002 GPS DATA" to exchange data with GPS.
Where is this variable defined?
Is there any other named variable usable to retrieve other information?
Is it possible to get traffic info through a named variable?

If someone can answer one of these question, it would help...
Thanks in advance !!
