'* The following code demonstrates the use of the ReadControlValue()
'* function to identify the items that were selected from a ListBox and
'* MultiListBox.  The return values (selected list item number and item
'* contents) are read into variables - an array variable for the multilist
'* box and a string variable for the list box - so that the return values 
'* will be accessible outside of the Dialog Box's OK Handler.
