      WAIT &H3DA,8 happens to work like this:
      Wait for screen to flicker off (WAIT &H3DA,8 )
      Draw graphics to screen

      Meaning that you don't see the graphics being drawn, hence reducing flicker.

      Now, the WAIT &H3DA,8 and WAIT &H3DA,8,8 used together work like this:
      Wait for screen to flicker off (WAIT &H3DA,8 )
      Draw graphics to screen
      Wait for screen to flicker on (WAIT &H3DA,8,8 )
      So before the program proceeds, it waits for the graphics to be displayed.
