status.i4.v = window_init_sequential_write_c(window_id.i2.v [,row.i4.v])

	This routine reinitializes the window row pointer for sequential
	writes to the window indicated by "window_id".

	window_id	window ID (use WMNGR_BACKGROUND for background window)
	[row]		next row for sequential I/O
			(default is WMNGR_INITIAL_ROW)

	This function returns ACNET status values as follows:

	OK			success
	CBS_NO_WINDOW		requested window does not exist
	CBS_MEMFAIL		dynamic memory allocation failure

	This function requires the following include files:

	cbslib_h, acnet_errors_h
