window_enable_scroll_status_c

	status.i4.v = window_enable_scroll_status_c(window_id.i2.v
						    [,display_attr.i4.v])

	This routine allows the programmer to enable display of the
	scroll buffer status field.

	window_id	window ID
	[display_attr]	display attributes
			(WMNGR_DISPLAY_ALWAYS -> display all the time
						 (default),
			 WMNGR_DISPLAY_WHEN_NEEDED -> display only if there
						      are lines in the
						      scroll buffer)

	This function returns status values as follows:

	CBS_INVARG		background or invalid window ID or display
				attribute was specified
	CBS_NO_WINDOW		window doesn't exist
	CBS_MEMFAIL		dynamic memory allocation failure
	TRUE			display was previously enabled
	FALSE			display was previously disabled

	This function requires the following include files:

	cnsparam_h, cbslib_h, acnet_errors_h
