Opens a dialog to define two file names. While originally intended for file parsing applications,
          this dialog function has been made general purpose for any application where the user needs to be
          prompted to select two file names. The dialog has file selection buttons which open a typical
          File Selection Dialog. The first file is the Input file and must exist on disk when the dialog is closed.
          The second file is the Output file and doesn't need to exist when the dialog is closed.

            The first argument defines the two file names and the description combo box text.
        
        
            The second argument configures the displayed text on the dialog including the caption, title,
          group box titles and so on.
        
        
            The third argument configures how the program remembers the input and output file names,
          description text and checkbox state. Each of these strings is a key in the user's configuration file,
          allowing the dialog to be used for many different applications with different memories.
          These remembered values will be displayed in the file and descriptive text combo boxes the next time
          the dialog is opened. The program remembers the last 10 file and description entries.

            Argument 1
        
        
            The argument is a string array of length 3 which defines the input file,
              output file and description text. Additional arguments add GUI elements to the dialog.
              If the 4th element is passed, the dialog is configured with a set of checkboxes inside
              the
            
                Options
            
            group at the bottom of the dialog. Each additional argument up to
              the 7th element represents a checkbox. The
            
                Options
            
            group of checkboxes was added
              to SIMetrix/SIMPLIS Version 8.10c.
