  21.  
  22.     This module uses the StandardFile interface to get the name of a file
  23.     containing an 'snd ' 128 resource. It then plays the sound asynchronously
  24.     to the handset until the user presses the mouse button or the
  25.     sound is finished playing. If the compile time option SND_RESOURCE is undefined
  26.     then the sound is taken from an AIFF file instead of a sound resource.
