Airport List in TTools

right, 
quick question here. If im adding an airport to the airport list in TTools, what does the last number mean
eg:
KLAX,N33* 56.53',W118* 24.46',125
What does the Number underlined mean.
At first i thought it was the heading but looking at some it seems the have larger numbers than 360.
thanks
