*
*
*	AN string		;	string = Airspace Name
*	AH string		;	string = Airspace Ceiling
*	AL string		;	string = Airspace Floor
*	AT coordinate	;	coordinate = Coordinate of where to place a name label on the map (optional)
*					;	NOTE: there can be multiple AT records for a single airspace segment
*	
*	
*	TERRAIN-related record types (NYI):
*	==============================
*
*	TO	{string}				; Declares Terrain Open Polygon; string = name (optional)
*	TC	{string}				; Declares Terrain Closed Polygon; string = name  (optional)
*	TX							; Specifies the center of the label where terrain name should be placed (optional record)
*	SP style, width, color		; Selects Pen to be used in drawing
*	SB color					; Selects Brush to be used in drawing
*
* 
*	Record types common to both TERRAIN and AIRSPACE
*	=================================================
*
*	V x=n			;	Variable assignment.
*					;	Currently the following variables are supported:
*					;	D={+|-}	sets direction for: DA and DB records
*					;					'-' means counterclockwise direction; '+' is the default
*					;					automatically reset to '+' at the begining of new airspace segment	
*					;	X=coordinate	: sets the center for the following records: DA, DB, and DC	
*					;	W=number		: sets the width of an airway in nm (NYI)
*
*
*	DP coordinate					; add polygon pointC
*	DA radius, angleStart angleEnd	; add an arc, angles in degrees, radius in nm
*	DB coordinate1, coordinate2		; add an arc, from coordinate1 to coordinate2
*	DC radius						; draw a circle (center taken from the previous V X record, radius in nm
*	DY coordinate					; add a segment of an airway (NYI)
