PUBLIC SUB Form_MouseWheel()
  
  
  SELECT CASE Mouse.delta
    
    CASE 1 
        PRINT "mouse wheel up"
    CASE -1 
         PRINT "mouse wheel down"
  
  END SELECT   

END

I don't know about sdl. You could use aumix. i.e

SHELL "aumix -v +5" WAIT

increase the current main volume by 5 points.

SHELL "aumix -v -25" WAIT 

decrease the current main volume by 25 points.

SHELL "aumix -v 100" WAIT 

set the volume to the maximum. Et cetera...

See aumix --help and do some experiments.

P.S. I'm not sure thet aumix is on all GNU/linux systems around ;-)

Ciao.
