	!-------
	! Generic ON/OFF indicators. GR__OFF is used to indicate OFF status for 
	! terminal, plotter and graphics decoding. GR__ON is used to indicate ON status
	! for graphics decoding.

	integer		GR__OFF, GR__ON
	parameter	(GR__OFF	= 0)
	parameter	(GR__ON		= 1)

	!-------
	! GR__NONE is used to indicate 'no plotter selected' and
	! 'no terminal selected'. MUST be equal to GR__OFF.

	integer		GR__NONE
	parameter	(GR__NONE	= GR__OFF)

	!-------
	! Types of displays (terminals):
	! use consecutive values with GR__GRAPHON the lowest and GR__X the highest
	! (GR__GRAPHON and GR__X are used to declare arrays in InitCoordSystem)

	integer		GR__GRAPHON, GR__AMIGA, GR__TEK, GR__X
	parameter	(GR__GRAPHON	= 1)
	parameter	(GR__AMIGA	= 2)
	parameter	(GR__TEK	= 3)
	parameter	(GR__X		= 4)

	!-------
	! Types of plotters (printers):
	! GR__CAPTURE can be set to any value. The remaining plotters should be set
	! to consecutive values with GR__HP the lowest and GR__LNO the highest
	! (GR__HP and GR__LNO are used to declare arrays in InitCoordSystem)

	integer		GR__HP, GR__PS, GR__LNO, GR__CAPTURE
	parameter	(GR__HP		= 1)
	parameter	(GR__PS		= 2)
	parameter	(GR__LNO	= 3)
	parameter	(GR__CAPTURE	= 4)

	!-------
	! Types of coordinate systems:
	! use consecutive values with GR__DEVI the lowest and GR__WARP the highest 

	integer		GR__DEVI, GR__USER, GR__NORM, GR__WARP
	parameter	(GR__DEVI	= 1)
	parameter	(GR__USER	= 2)
	parameter	(GR__NORM	= 3)
	parameter	(GR__WARP	= 4)

	parameter	(MAX_COLORS	=16)
