The following commands were left out of the library reference:

wcopymap
------------------------------------------------------------------------------
Function:	Makes a scrolling window share a map with another window.     

Declaration:	void wcopymap (int sourcewindow, int destwindow)

Remarks:	This command allows you to have two scrolling windows on the
		screen at once which use the same map.  This is perfect for two 
		player games.  Any changes made to the map with wputworldblock
		update both windows at the same time.  Note that you can have
		as many windows sharing a map as you want.  This is also useful
		for creating a reduced view map which scrolls along with a
		larger one.

Parameters:	sourcewindow - Window containing loaded map.

		destwindow   - Window to assign duplicate map.
		
Return Value:	None

Examples:	59


wscreen_coordx
------------------------------------------------------------------------------
Function:	Returns the absolute X screen coordinate of a world 
		coordinate. 

Declaration:	int wscreen_coordx (int currentwindow, int xcoord)

Remarks:	This command is used to find out if a sprite is on the screen
		and where it appears.  It can be used for sound effects  
		panning or to find out the scrolling speed of a window.

		If returned coordinate is between 0 and the window width,
		it is within the window.

Parameters:	currentwindow - Window to base coordinate system.

		xcoord        - World coordinate on map.
		
Return Value:	Screen coordinate of the object.

wscreen_coordy
------------------------------------------------------------------------------
Function:	Returns the absolute Y screen coordinate of a world 
		coordinate. 

Declaration:	int wscreen_coordy (int currentwindow, int ycoord)

Remarks:	This command is used to find out if a sprite is on the screen
		and where it appears.  It can be used for sound effects  
		panning or to find out the scrolling speed of a window.

		If returned coordinate is between 0 and the window height,
		it is within the window.

Parameters:	currentwindow - Window to base coordinate system.

		ycoord        - World coordinate on map.
		
Return Value:	Screen coordinate of the object.
