sda_usage_menu_c

	status.i4.v = sda_usage_menu_c(title.i1a.r, top_row.i4.v,
				       left_column.i4.v, sda_usage.i4.r,
				       cursor_handling.i4.v)

	This routine displays a menu of Sequenced Data Acquisition (SDA) usages.

	title		title of input window  (Note: A null pointer may be
			passed if no title is desired.)
	top_row		top row of menu (use WMNGR_CENTER for centering
			or WINDOW_xxx_COORD macros in macro for special
			positioning)
	left_column	left column of menu (use WMNGR_CENTER for centering
			or WINDOW_xxx_COORD macros in macro for special
			positioning)
	sda_usage	returned SDA usage
	cursor_handling	cursor positioning after the menu is closed
			(WMNGR_LEAVE_CURSOR -> leave cursor where it is when
					       the menu is closed,
			 WMNGR_RESTORE_CURSOR -> position the cursor where
						 it was located when the
						 menu was created,
			 CLIB_DEFAULT_ARG -> use cursor handling set up by
					     the most recent call to
					     menu_setup_c)

	This function returns ACNET status values as follows:

	OK			success
	CLIB_MEMFAIL		dynamic memory allocation failure
	CBS_WINDOW_TOO_BIG	window won't fit on screen
	CLIB_ABORT		user aborted input

	This function requires the following include files:

	cnsparam_h, cbslib_h, macro_h, acnet_errors_h
