Referencing hyperblocks
If you reference the index cell of a hyperblock in a formula, the
                           		  unique name is returned, whatever output format is selected in the 
                           		  Output Properties or 
                           		  Format Cells dialogs. To return the caption, use
                           		  the Text function, for example, 
                           		  =Text(B5,"~"), where B5 is the reference of the index
                           		  cell.
