menu_change_entry_case_c

	status.i4.v = menu_change_entry_case_c(menu_id.i4.v, item.i4.v,
					       type.i4.v, color.i4.v)

	This routine will change the text case and/or color of a menu item
	in a menu created by an earlier call to menu_create(_c).

	menu_id		menu ID (returned by a prior call to menu_create(_c))
			(a value of MENU_TOP will result in deleting the
			 most recently created menu)
	item		item number to change (starts at 1)
	type		type of case conversion
			(STR_UP_CASE_STRING -> make all lower case characters
					       upper case,
			 STR_DOWN_CASE_STRING -> make all upper case
						 characters lower case)
	color		text color (If a value of CLIB_DEFAULT_ARG is
			passed for this argument, the text color will
			remain unchanged.)
			(constants are in 'cnsparam')

	This function returns ACNET status values as follows:

	OK			success
	CBS_INVARG		invalid case conversion or item requested
	CBS_NO_SUCH		menu does not exist
	CBS_NOTENB		requested item is a separator

	This function requires the following include files:

	cnsparam_h, cbslib_h, acnet_errors_h
