   The actual PV-WAVE code for this demo can be found in the files :    
                                                                        
      $WAVE_DIR/demo/gallery/bsc_demo*.pro      (UNIX Systems)          
         OR                                                             
      WAVE_DIR:[demo.gallery]bsc_demo*.pro      (VMS Systems)           
         OR                                                             
      %WAVE_DIR%\demo\gallery\bsc_demo*.pro	(Windows NT Systems)

   ("WAVE_DIR" is the directory where PV-WAVE is installed.)            
                                                                        
   To run this demo outside of the Gallery (stand-alone mode),          
   start PV-WAVE and enter the following command :                      
                                                                        
      PV-WAVE> bsc_demo

This demo shows PV-WAVE's basic capabilities and functions 
for reading in and displaying 1-D, 2-D, 3-D, and 4-D data.

When ready, click on "DONE" and then select the data display type
from the menu that will appear.

The PV-WAVE code to display a menu, get a choice from the user,
and run the appropriate procedure is remarkably simple.
The following section of PV-WAVE code from the file "bsc_demo.pro"
will perform these actions until the "QUIT" entry on the menu is
selected :

   ;*************************************************************
   text = Strarr(5)
   text(0) = '     1-D Display (Line Plot)          '
   text(1) = '     2-D Display (Image, Contour)     '
   text(2) = '     3-D Display (Surface)            '
   text(3) = '     4-D Display (Shaded Surface)     '
   text(4) = '     EXIT                             '

   choice = 0
   WHILE (choice LT 4) DO BEGIN
      choice = Wd_Demo_Menu(text, [150, 450], $
               Title='Select Data Display Type :')
      CASE choice OF
         0: BEGIN
               Bsc_Demo1, seconds, test1, test2
            END
         1: BEGIN
               Bsc_Demo2, seconds, test1, test2
            END
         2: BEGIN
               Bsc_Demo3, seconds, test1, test2
            END
         3: BEGIN
               Bsc_Demo4, seconds, test1, test2
            END
         4:
      ELSE:
      ENDCASE

   ENDWHILE
