window_write_xchar_line_c

	status.i4.v = window_write_xchar_line_c(window_id.i2.v, text.sa.r,
						num_chars.i4.v
						[,num_lines.i4.v])

	This routine writes one or more XCHAR strings to the indicated window
	in a sequential fashion.  Successive calls to this routine for a
	given window will cause the scrolling region of the window to be
	filled from top to bottom.  When the window is full, the next and
	subsequent calls will create entries in the window's scroll buffer.
	If multiple lines of varying lengths are to be displayed, "num_chars"
	should be set to zero, and each successive line's text should be
	separated by a single null character.  If the window is erased or for
	any reason it is desired to start writing at the top of the scrolling
	region again, a call to window_init_sequential_write_c is required.

	window_id	window ID (use WMNGR_BACKGROUND for background window)
	text		text string to be displayed (array of XCHAR structures)
	num_chars	number of characters in string (If this has a
			value of 0, characters will be displayed until
			a null character is encountered.)
	[num_lines]	number of lines of text (default is 1)

	This function returns ACNET status values as follows:

	OK			success
	CBS_INVARG		invalid number of characters (<0)
	CBS_NO_WINDOW		requested window does not exist
	CBS_MEMFAIL		failed in allocating dynamic memory
	CBS_TOO_MANY		scroll buffer is full

	This function requires the following include files:

	cnsparam_h, cbslib_h, acnet_errors_h
