window_row.i4.v = window_row(window_id.i2.r, row.i4.r)

	window_row.i4.v = window_row_c(window_id.i2.v, row.i4.v)

	This routine converts a TV row value into the row value relative
	to the window specified by "window_id".  If the row value lies
	outside of the window, a value of CBS_NOT_IN_WINDOW will be returned.

	window_id	window ID (use WMNGR_BACKGROUND for background window)
	row		row to be converted

	This function returns status values as follows:

	CBS_NO_WINDOW		requested window does not exist
	CBS_NOT_IN_WINDOW	requested row is not in the window
	otherwise		equivalent window row

	This function requires the following include files:

	cbslib_h, acnet_errors_h

	Related functions:

	window_column(_c), screen_row(_c), screen_column(_c), intro_tv_windows

	C/C++ usage:

	short	window_id;
	int	window_row;
	int	row = 1;

	window_row = window_row_c(window_id,row);
