clockscope_directory

	selected_entry.sp.v = clockscope_directory(top_row.i4.v,
						   left_column.i4.v)

	This routine displays a directory of saved clockscope data.

	top_row		top row of window (use WMNGR_CENTER for centering
			or WINDOW_xxx_COORD macros in macro for special
			positioning)
	left_column	left column of window (use WMNGR_CENTER for centering
			or WINDOW_xxx_COORD macros in macro for special
			positioning)

	This function returns status values as follows:

	NULL			no entry selected
	otherwise		pointer to selected directory entry
				(structure of type cs_entry_t)

	This function requires the following include files:

	cnsparam_h, ul_cbsaux_h:clockscope_h, cbslib_h, macro_h

	clocklog_directory, clocklog_dates, clocklog_save, clocklog_recall

	C/C++ usage:

	int	top_row = WMNGR_CENTER;
	int	left_column = WMNGR_CENTER;
	cs_entry_t	*selected_entry;

	selected_entry = clockscope_directory(top_row,left_column);
